Discover the essential characteristics of El Niño and La Niña. Understand the fundamental distinctions between these two climatic events.


The dance between El Niño and La Niña, two significant climatic phenomena, is all about the geographic distribution of heat: it shapes the weather patterns around the equatorial Pacific Ocean. El Niño emerges as a warming phase in the Eastern and Equatorial Pacific, while its counterpart, La Niña, brings anomalous heat to the Western and Tropical Pacific.

Together, they partake in a global rhythm that affects the Equatorial Pacific Ocean and extends its reach to the South American coastlines and the broader Pacific. This delicate equilibrium is pivotal to understanding the climatic intricacies that drive atmospheric circulation, forest fires, rainfall patterns, and even fish crop across our planet.

### What are El Niño and La Niña?

El Niño is characterized by the abnormal warming of ocean waters in the central and eastern Pacific, while La Niña is identified by the abnormal cooling of these same waters.

These irregular cycles are not just oceanic events; they resonate globally. Their influences extend far beyond their Pacific origin, dictating weather alterations across continents. The irregular nature of El Niño and La Niña means that they aren’t always in full swing: some years are actually free of anomalies. Nevertheless, recognizing the heating caused by El Niño and the cooling caused by La Niña is essential for predicting and understanding the vast array of meteorological impacts they induce.

### Characteristics of El Niño and La Niña

The defining traits of El Niño and La Niña, two formidable climatic phenomena, hinge on three key characteristics: 

- Duration
- Intensity
- Typical onset dates

El Niño episodes often present with elevated sea surface temperatures that persist for several months, manifesting an intensity that can alter global weather patterns. In contrast, La Niña is noted for a cooling phase that can endure beyond the span of a year, underscoring the formidable magnitude of its impact.

The initiation of these episodes follows a natural, yet unpredictable cadence, with El Niño typically beginning in the central and eastern Pacific Ocean around late spring of the Southern Hemisphere. La Niña, often following El Niño’s lead, tends to emerge during autumn. This rhythm of heating and cooling significantly influences seasonal weather patterns, from intensifying rainfall to prolonging droughts, demonstrating a powerful sway over the Earth’s atmospheric systems.

### Causes of El Niño and La Niña

Both El Niño and La Niña are deeply rooted in the dynamics of the Pacific Ocean and the Earth’s atmosphere, particularly through the interplay of trade winds, thermocline variations, and oceanic upwelling. Trade winds typically blow westward across the Tropical Pacific, piling up warm surface waters in the west and allowing cooler waters to rise near South America, a process known as upwelling. 
During El Niño, these winds weaken or may even reverse, reducing upwelling and causing a shallow thermocline, leading to an extensive warming of the central and eastern Pacific Ocean. This shift in heat distribution disrupts the Walker circulation, a pattern of atmospheric circulation that normally sees air rising in the warm west and falling in the cooler east, thus impacting weather systems on a global scale. West Pacific is particularly impacted, manifesting in less precipitation in countries like Indonesia, Australia, and the Philippines.
On the flip side, La Niña occurs when these trade winds strengthen beyond their normal intensity, enhancing the upwelling of cold, nutrient-rich waters along the equatorial Pacific. This process deepens the thermocline and expands the area of cooler water at the surface. The strengthened Walker circulation cells during La Niña can lead to drought in the Eastern Pacific and increased rainfall in the Western Pacific.

These complex interactions between the ocean and atmosphere during El Niño and La Niña episodes influence the local weather and trigger a cascade of effects that can alter global climate patterns. This includes shifts in jet streams, variations in storm tracks, and the distribution of heat and precipitation around the planet. As such, the study of these phenomena is crucial for forecasting weather and understanding the broader impacts on ecosystems, agriculture, water resources, and human societies.

### Effects and Consequences

El Niño and La Niña exert profound global impacts, yielding a range of consequences that touch every corner of the Earth. Their influence is most noticeable in altered temperatures and precipitation patterns, which go on to dictate not only the health of natural ecosystems but also the viability of human activities such as agriculture and fishing.

During El Niño, the warming of the Pacific Ocean can lead to increased rainfall in some regions while causing drought in others. In agricultural terms, this can result in decreased yields in drought-stricken areas, while potentially boosting growth where the rains are bountiful. However, too much rain can also be bad news for mountainous regions like Peru. The fishing industry also feels the impact, as warmer waters disrupt marine life’s food chains and habitats, often leading to poor catches.

Conversely, La Niña typically promotes cooler atmospheric conditions and increases the intensity and frequency of rainfall in places such as the Western Pacific and the Northeast of South America. This can benefit crops that depend on water, but excessive rainfall can also cause devastating floods that destroy crops and infrastructure. In the fishing industry, the cooler waters associated with La Niña can lead to an abundance of marine life in certain areas as nutrient-rich cold water rises to the surface.

The economic effects of these climatic events are significant. They can lead to fluctuations in commodity prices, influence energy demand, and require businesses to adapt their strategies to cope with the variable supply of raw materials and goods. The uncertainty and risk associated with El Niño and La Niña underscore the need for businesses to have access to accurate climate forecasts.

In light of these challenges, it is crucial for companies to stay informed and prepared. Understanding the potential business implications of these phenomena is key to mitigating risks and capitalizing on opportunities.

### El Niño and La Niña in Brazil

El Niño and La Niña distinctly mark their presence in Brazil, a country with a tapestry of climates and terrains. In Brazil, El Niño is often synonymous with drought in the Northeast and floods in the South. The scarcity of rain in the North hampers agriculture, strains water resources, and challenges daily life. Conversely, the South sees heavy rains, resulting in floods that overflow rivers, damage crops, and displace communities.

La Niña brings a contrasting touch to the Brazilian climate. It typically alleviates the dry conditions in the Northeast, offering some respite to the parched lands, yet it can also mean less rainfall for the South, occasionally leading to water shortages and impacting hydroelectric power generation.

With its economic hub São Paulo, the Southeast experiences irregular patterns during these periods, which can affect the region’s powerhouse status by influencing water supply and energy production. The ebb and flow of these phenomena underscore the need for regional resilience and adaptive strategies to weather the effects of these powerful climatic forces. Understanding these patterns is vital for Brazil's preparedness and response to the environmental and economic challenges posed by El Niño and La Niña.

### Conclusion

In conclusion, El Niño and La Niña serve as pivotal forces in the global climatic narrative, each with distinct characteristics, causes, and far-reaching effects. They orchestrate changes in weather patterns that extend well beyond their Pacific epicenter, influencing temperatures, precipitation, and the livelihoods of communities worldwide. 

As we unravel the complexities of these phenomena, we glean a deeper understanding of Earth’s intricate weather systems, equipping us to anticipate and respond to their profound environmental and socioeconomic impacts. Their study is not merely academic but a necessity for a world that must adapt to an ever-changing climatic stage.

El Niño and La Niña: What They Are, Differences

What causes ball lightning? What is ball lightning? This is our pick of the most mind-boggling facts about ball lightning. Let's unriddle at least some of the riddles.

Ball lightning is described as shining spherical objects floating around or hovering above the ground. Most of the eye-witness accounts describe this enigmatic phenomenon as balls of fire or electricity. Despite plenty of evidence that exists, scientists are not any closer to figuring it out, and we see more and more wild speculations about these mysterious spheres of light. The internet is full of ball lightning photos believed to be real. However, most of them are manipulated images.
What causes ball lightning? What is ball lightning? This is our pick of the most mind-boggling facts about ball lightning. Let's unriddle at least some of the riddles.

## Amazing facts about ball lightning: 

- There is no accepted theory for what causes it or what it is made of (there are over 400 existing hypotheses that describe the nature of ball lightning). One of the theories suggests that these balls of fire consist of electrons and force-activated ions. Some scientists agree that the origin of this phenomenon is sustained by electromagnetic waves generated when the Earth's crust fractures. When the Earth's surface is shaking during an earthquake or minor shocks, these flows of electromagnetic waves soar into the air giving rise to luminescent spheres.
Due to the nature of this rare phenomenon having a lifetime of a few seconds, scientists have not succeeded in making extensive observations of these luminous spheres or in studying their properties.
- Ball lightning is common during thunderstorms. At other times, its causes have no relation to weather conditions.
- All attempts to produce ball lightning in the lab proved to be fruitless: though some motley crews of scientists could bring luminous objects to life, none of them could re-create the original nature of these objects.  The thing is ball lightning looks like plasma bubbles that can't last long in lab conditions.
- A "typical" ball lighting is the size of a cabbage head. There were rare eye-witnesses saying the hovering objects varied from several millimeters to few meters in diameter. Ball lightning can take different forms: it can be round, pear-shaped, circular, ellipsoid, to name just a few.

- According to the research made by Alexander Grigoriev, a scientist from the city of Yaroslavl, Russia, ball lightning lasts for seconds to hours and vanishes following no particular pattern: either silently or with a blast, disappearing when striking the ground or hitting any type of conductor.

- Ball lightning emits light: sometimes dim, sometimes very intense. Ball lighting can travel at speed ranging from a few centimeters per minute to tens of meters per second.

- These floating spheres can range in color from white to yellow to green, or be even translucent.

- Information about the dangers caused by ball lightning varies enormously: while some witnesses struck by the sphere say they have not suffered any burns, others claim they saw ball lightning setting a haystack alight or even killed people.
 
- Most commonly, ball lightning zips around 1.5 meters above the ground. Still further, it can go several kilometers up from the ground.

- In 1963, ball lightning passed through a US passenger aircraft and vanished instantly not hurting anyone aboard or causing damage to the plane.

- Medveditsk ridge (Russia) located at the border of the Saratov and Volgograd regions is considered to be an anomaly site with the biggest number of ball lightning occurrences across the globe.




Ball lightning. What causes ball lightning? The most incredible facts about this phenomenon


The role of natural factors in amplifying or mitigating air pollution.

In environmental issues, industry is often the primary scapegoat. However, nature itself can exacerbate pollution: due to various weather conditions, harmful emissions can either accumulate in one area or spread widely. Details in our post.

### Wind and Atmospheric Pressure
Air is constantly moving, spreading pollutants from one place to another and even across borders. For example, acid rains in Sweden are caused by sulfur and nitrogen oxides carried by winds from UK and German industries. Asia faces its own weather phenomenon - yellow dust. Powerful spring winds pick up dust particles from the Gobi Desert located in China and Mongolia and sweep it over the Korean Peninsula and Japan.

Within industrial hubs, even a low wind speed can pose a threat. At speeds of 1–2 m/s, toxic substances from ventilation systems settle on the ground, and at 4–6 m/s, from large power plants. The direction matters too; wind blowing from factories towards city centers will lead to pollution.

The most dangerous situation is a calm associated with a high-pressure area or anticyclone. Pollutants remain near the ground, trapped in one region. Conversely, in low-pressure areas or cyclones, swirling currents rise and precipitation occurs, scattering or washing away pollutants.

### Air Temperature and Humidity
Temperature affects air movement: warmer, lighter currents rise and cooler, denser ones sink, a phenomenon called convection. Which pollutants travel depends on seasonal weather.

### Cold Weather Impact
In cold seasons, exhaust fumes and smoke are more noticeable. One might wonder whether it’s just more visible or if there's more pollution. The answer is both. Firstly, exhausts are a mix of carbon dioxide, nitrogen, warm steam, and harmful impurities. We see condensed water droplets when steam hits cold temperatures. Moreover, during late autumn and winter, vehicles often idle, burning extra fuel and producing more emissions.

Secondly, even if industrial waste remains constant throughout the year, there's more heating during colder months, releasing carbon monoxide and other toxic hydrocarbons.

Temperature inversions can exacerbate the situation. Typically, warm air rises, carrying pollutants that disperse over large areas. But sometimes, a layer of unusually cold air forms at the ground with warmer air above, preventing the cold air from rising. This traps pollutants below, resulting in smog.

### Heat Impact
During hot periods, ground-level ozone accumulates in cities and rural areas. In the stratosphere, this gas protects against ultraviolet rays, but at ground level, it's harmful. It's advisable to stay indoors during extreme heat, tracking hourly forecasts on our service. Luckily, summer often brings seasonal thunderstorms. Scientists note that high humidity helps break down ozone, so rain reduces it, and clouds inhibit its production.

May the air in your city be pure and your mood cloudless!

During the course of a month, the Moon goes through several phases. The major Moon phases are the new moon, the first quarter, the full moon, and the third quarter. As a matter of fact, the Moon displays eight main phases. We'll dive deeper into these phases to find out why this Earth's most constant companion changes its appearance night after night.

During the course of a month, the Moon goes through several phases. The major Moon phases are the new moon, the first quarter, the full moon, and the third quarter. As a matter of fact, the Moon displays eight main phases. We'll dive deeper into these phases to find out why this Earth's most constant companion changes its appearance night after night.


## Understanding the phases of the Moon

Lunar phases are the shapes of the visible part of the satellite from Earth's perspective. Fun fact: the illuminated edge of the Moon's visible surface is called the limb, while the line that separates the illuminated and the shaded sections is the Moon's terminator (a word derived from the Latin "terminare", which means "to set bounds to").

As the Moon goes around the Earth, the Sun illuminates different parts of the Moon, which changes its appearance and creates lunar phases.

Examples of terminology relating to lunar phases that is commonly used by the scientific community:
* The Moon cycle, which is one full orbit by our Moon around the Earth. It takes 29.5 days.
* A Synodic month, or a Lunation, being the time between two successive new moons.
* The age of the Moon, which is the number of days since the last new moon.

![](https://avatars.mds.yandex.net/get-weather/10931474/aFgVIzcPdWaciFZlGEiB/orig)

## A guide to the phases of the Moon

There are 4 major phases of the Moon — the full moon, the new moon, the first and the last quarters. The 4 minor phases are waxing crescent, waxing gibbous, waning gibbous, and waning crescent. The major phases of the Moon occur about 7.4 days apart.

**New moon**

The Moon is between the Sun and the Earth. Thus, the side of the Moon facing the Earth is in shadow.

**Waxing crescent**

This phase follows the new moon, as the Moon starts to "grow". We only see the edge of the part that is gradually illuminated by the Sun.

**First quarter**

The Moon has completed 1/4 of its orbit around the Earth. Half of the Moon's surface is illuminated by the Sun.

**Waxing gibbous**

More than half of the Moon’s surface visible from Earth is illuminated.

**Full moon**

During this phase, the Earth is positioned between the Moon and the Sun, which illuminates the entire near-side of the satellite. We can enjoy the round appearance of the full moon all night long.

**Waning gibbous**

After the full moon, the illuminated part of the Moon begins to wane. During this phase, the surface of the Moon that we see from the Earth is still mostly illuminated.

**Last quarter**

The Moon looks like it is half illuminated.

**Waning crescent**

The final phase of the Moon before transitioning back into the new moon. Only a small, crescent-shaped sliver of the Moon is visible, which is diminishing in size.

Greenhouse gases (GHGs) are vital components of Earth's atmosphere that regulate the planet's temperature by trapping heat — a phenomenon known as the greenhouse effect.

Greenhouse gases (GHGs) are vital components of Earth's atmosphere that regulate the planet's temperature by trapping heat — a phenomenon known as the greenhouse effect. They function much like a thermal blanket, maintaining the warmth necessary to sustain life on Earth. However, human activities have significantly increased the concentrations of these gases, leading to global warming and climate change

Greenhouse gases (GHGs) are vital components of Earth's atmosphere that regulate the planet's temperature by trapping heat — a phenomenon known as the greenhouse effect. They function much like a thermal blanket, maintaining the warmth necessary to sustain life on Earth. However, human activities have significantly increased the concentrations of these gases, leading to global warming and climate change.

## The main greenhouse gases

Several types of greenhouse gases contribute to the greenhouse effect, each originating from different sources and possessing unique properties.

### Carbon dioxide (CO₂)

Carbon dioxide is the most prevalent greenhouse gas produced by human activities. It is primarily released through the burning of fossil fuels such as coal, oil, and natural gas for energy and transportation. Since the Industrial Revolution, atmospheric CO₂ concentrations [have risen](https://www.carbonbrief.org/met-office-atmospheric-co2-now-hitting-50-higher-than-pre-industrial-levels/) by about 50%, increasing from approximately 280 parts per million (ppm) in pre-industrial times to over 419 ppm as of 2021. This unprecedented rise is a significant driver of current climate change.

### Methane (CH₄)

Methane is a potent greenhouse gas with a [global warming potential](https://www.canada.ca/en/services/environment/weather/climatechange/climate-plan/reducing-methane-emissions/faster-further-strategy.html) more than 25 times that of CO₂ over a 100-year period. It is primarily produced through agricultural activities such as livestock farming and rice cultivation, as well as from the decomposition of organic waste in landfills and emissions from oil and gas extraction. Methane concentrations [have more than doubled](https://www.epa.gov/climate-indicators/climate-change-indicators-atmospheric-concentrations-greenhouse-gases) since pre-industrial times, contributing significantly to climate warming.

### Nitrous oxide (N₂O)

Nitrous oxide is mainly emitted from agricultural practices, especially the use of synthetic and organic fertilizers that enhance nitrogen availability in soils. It is also released during industrial processes and combustion of fossil fuels and biomass. N₂O has a global warming potential [approximately](https://www.caro.ie/knowledge-hub/general-information/science-of-climate-change/greenhouse-gases) 298 times that of CO₂ over a 100-year period, making it a significant contributor despite its lower concentration.

### Water vapor (H₂O)

Water vapor is the most abundant greenhouse gas in the atmosphere, though it is not directly emitted by human activities. Its concentration increases as the atmosphere warms because warmer air can hold more moisture. This creates a positive feedback loop: as temperatures rise due to other greenhouse gases, water vapor levels increase, which in turn amplifies the warming effect.

## How greenhouse gases work

The greenhouse effect involves the absorption and re-emission of infrared radiation by greenhouse gases, leading to the warming of the Earth's surface and lower atmosphere.

### The basic mechanism

Solar radiation from the Sun, primarily in the form of visible light and ultraviolet radiation, passes through the Earth's atmosphere and reaches the surface. The Earth's surface absorbs this energy, warming up in the process, and then re-emits it as longwave infrared radiation. Greenhouse gases in the atmosphere absorb some of this infrared radiation and re-emit it in all directions, including back toward the surface. This process traps heat in the lower atmosphere, raising the planet's average temperature. Without this natural greenhouse effect, Earth's average temperature [would be](https://www.earthobservatory.nasa.gov/features/GlobalWarming/page2.php) about –18°C (0°F) instead of the current average of approximately 15°C (59°F).

<figcaption>
</figcaption>
</figure>


### Specific mechanisms of different greenhouse gases

Each greenhouse gas absorbs infrared radiation at specific wavelengths, contributing differently to the greenhouse effect.

* **Carbon dioxide (CO₂)** [absorbs](https://michiganstopsmartmeters.com/how-does-co2-absorb-infrared/) infrared radiation at wavelengths around 15 micrometers and can remain in the atmosphere for centuries, making it a significant long-term driver of climate change.

* **Methane (CH₄)** absorbs infrared radiation at wavelengths near 7.66 micrometers. Although methane has a shorter atmospheric lifetime — about 12 years — it is [over 80 times](https://climate.nasa.gov/vital-signs/methane/?intent=121) more effective than CO₂ at trapping heat over a 20-year period.

* **Nitrous oxide (N₂O)** absorbs infrared radiation at wavelengths around 7.8 micrometers. With an atmospheric lifetime of about 114 years, it has a [long-term impact](https://www.soest.hawaii.edu/mguidry/Unnamed_Site_2/Chapter%202/Chapter2C3.html#:~:text=Nitrous%20oxide%20enhances%20the%20greenhouse,to%20destruction%20of%20stratospheric%20ozone) on warming.

* **Water vapor (H₂O)** absorbs infrared radiation across a wide range of wavelengths. Its concentration is directly related to temperature, leading to a feedback loop that amplifies warming caused by other greenhouse gases.

### The enhanced greenhouse effect

Human activities have intensified the natural greenhouse effect by increasing greenhouse gas concentrations in the atmosphere.

<figcaption>
</figcaption>
</figure>


**Increased concentrations:** Since the Industrial Revolution, atmospheric concentrations of CO₂, methane, and nitrous oxide have risen sharply due to activities such as fossil fuel combustion, deforestation, and industrial processes. For instance, CO₂ levels [have increased](https://newatlas.com/environment/atmospheric-co2-50-percent-higher-pre-industrial-levels/) from about 280 ppm in the pre-industrial era to over 419 ppm in 2021.

**Positive feedback loops:** Warming temperatures can trigger processes that release additional greenhouse gases, creating positive feedback loops. For example, thawing permafrost in Arctic regions releases methane and CO₂ previously trapped in frozen soils, further enhancing warming.

**Climate sensitivity:** Climate sensitivity refers to the amount of global temperature increase expected from a doubling of CO₂ concentrations compared to pre-industrial levels. [Current estimates](https://www.realclimate.org/index.php/archives/2021/08/notallmodels/) suggest a likely range of 2.5°C to 4°C, with a best estimate of around 3°C. Understanding climate sensitivity is crucial for predicting future climate impacts and informing policy decisions.

## Measuring and monitoring

Scientists use various methods to measure greenhouse gases and assess their impact on the climate. Understanding the mechanisms and impacts of greenhouse gases is essential for developing effective strategies to mitigate climate change.

**Direct atmospheric measurements:** Monitoring stations worldwide, such as the Mauna Loa Observatory in Hawaii, continuously measure atmospheric concentrations of greenhouse gases. These measurements provide critical data on how concentrations change over time.

**Satellite observations:** Satellites equipped with spectrometers measure the Earth's energy balance and the distribution of greenhouse gases in the atmosphere. They can detect changes in outgoing longwave radiation, offering insights into how the greenhouse effect is altering.

**Ice core analysis:** By examining air bubbles trapped in ice cores from Antarctica and Greenland, scientists reconstruct past atmospheric compositions, extending back hundreds of thousands of years. This information helps contextualize current greenhouse gas levels within historical variations.

**Spectroscopy:** Spectroscopic techniques identify specific greenhouse gases by their unique absorption spectra, enabling precise measurements of atmospheric composition and the study of gas interactions with radiation.

## Kazakhstan: a case study in greenhouse gas emissions

Kazakhstan offers a compelling example of the challenges and efforts associated with greenhouse gas emissions in a developing economy.

### Emissions profile

<figure>

![/](https://avatars.mds.yandex.net/get-weather/10879918/QaSszpZNVfZhiLLInNRS/orig)

<figcaption>
</figcaption>
</figure>


[In 2021](https://icapcarbonaction.com/system/files/ets_pdfs/icap-etsmap-factsheet-46.pdf), Kazakhstan's total greenhouse gas emissions were approximately 338 million metric tons of CO₂ equivalent, marking an increase from previous years. The energy sector is the largest contributor, [accounting](https://www.usaid.gov/energy/auctions-kazakhstan) for about 82% of the country's total emissions in 2015. This high percentage reflects Kazakhstan's heavy reliance on fossil fuels, particularly coal, for electricity generation and industrial processes.

Per capita, Kazakhstan's emissions are relatively high, [standing](https://data.jrc.ec.europa.eu/collection/edgar) at around 17.3 metric tons of CO₂ equivalent per person as of 2022. This ranks the country among the top emitters on a per capita basis, highlighting its energy-intensive economy.

Kazakhstan contributes [approximately](https://data.jrc.ec.europa.eu/collection/edgar) 0.6% of global greenhouse gas emissions, making it one of the top 30 emitters worldwide. While this may seem small in global terms, it is significant for a nation with a population of about 19 million.

### Climate change impacts in Kazakhstan

The effects of increased greenhouse gas emissions are already apparent in Kazakhstan.

**Rising temperatures:** Between 1941 and 2020, the average annual temperature in Kazakhstan [increased](https://bnrc.springeropen.com/articles/10.1186/s42269-023-01122-w) by about 2°C, exceeding the global average temperature rise. This warming trend affects agriculture, water resources, and ecosystems, potentially threatening food security and livelihoods.

**Extreme weather events:** Kazakhstan has experienced an increase in extreme weather events, including droughts, floods, and heatwaves. These events have substantial social and economic impacts, damaging infrastructure and affecting public health.

**Glacial retreat and water resources:** The country's glaciers are retreating, which threatens water supplies for agriculture and human consumption in downstream regions. Reduced glacial meltwater can lead to water shortages during dry seasons.

**Desertification:** Increasing temperatures and changing precipitation patterns contribute to desertification, impacting arable land and biodiversity.

### Mitigation efforts

Kazakhstan has implemented several strategies to reduce its greenhouse gas emissions and address climate change.

**Emissions trading system:** In 2021, Kazakhstan [adopted](https://icapcarbonaction.com/en/ets/kazakhstan-emissions-trading-system) a new Environmental Code that includes an emissions trading system. This market-based approach aims to incentivize emission reductions in the industrial sector by setting caps and allowing trading of emission allowances.

**Renewable energy expansion:** The country is increasing its share of renewable energy sources. [By 2021](https://www.undp.org/kazakhstan/news/reducing-temperatures-kazakhstan-takes-action-against-climate-change), Kazakhstan had over 115 renewable energy facilities in operation, including wind, solar, and hydropower plants. The government [aims](https://daryo.uz/en/2024/07/26/central-asia-advances-green-energy-with-initiatives-and-regional-cooperation) to produce 15% of its electricity from renewable sources by 2030 and 50% by 2050.

**Transition to natural gas:** Kazakhstan is transitioning from coal to natural gas for electricity generation and heating. Projects like the "[Saryarka](https://astanatimes.com/2020/01/kazakh-government-commissions-saryarka-gas-pipeline/)" gas pipeline are expanding access to natural gas, particularly in regions previously reliant on coal. This shift reduces carbon intensity and improves air quality.

**International commitments:** Kazakhstan [has pledged](https://astanatimes.com/2020/12/tokayev-announces-kazakhstans-pledge-to-reach-carbon-neutrality-by-2060/) to achieve carbon neutrality by 2060 as part of its commitment to the Paris Agreement. The country submitted its updated Nationally Determined Contribution (NDC) in 2021, aiming to reduce greenhouse gas emissions by 15% by 2030 compared to 1990 levels.

**Energy efficiency initiatives:** Efforts are underway to improve energy efficiency across various sectors, including industry, transportation, and buildings. This includes adopting new technologies, enhancing regulations, and promoting public awareness to reduce energy consumption.

As global efforts to combat climate change intensify, countries like Kazakhstan will play a crucial role. Their ability to transition to cleaner energy sources and implement effective climate policies is vital in the global fight against climate change. Continued international cooperation, technological innovation, and investment in sustainable practices are essential to support these transitions.

Hurricanes have long captivated and terrified coastal communities, but recent research suggests these massive storms are becoming even more formidable in the face of climate change. Understanding and predicting hurricanes is more crucial than ever, as these natural phenomena pose increasing risks to life, property, and economies globally.

## The anatomy of a hurricane

Hurricanes, also known as tropical cyclones in other parts of the world, are complex atmospheric phenomena that develop over warm tropical oceans. These massive storm systems are characterized by their rotating structure, intense winds, and heavy rainfall.

### Formation process

1. **Tropical disturbance**: The genesis of a hurricane [begins](https://oceanservice.noaa.gov/facts/how-hurricanes-form.html) with a tropical disturbance — a cluster of thunderstorms over warm ocean waters. These disturbances often originate from easterly waves, which are elongated areas of low air pressure moving westward across the tropics.

2. **Tropical depression**: As the system organizes and the pressure drops, it [becomes](https://scijinks.gov/hurricane/) a tropical depression with sustained winds up to 38 mph (61 km/h). A closed circulation begins to form, indicating the system is gaining strength.

3. **Tropical storm**: When sustained winds [reach](https://scijinks.gov/hurricane/) 39–73 mph (63–118 km/h), it’s classified as a tropical storm and is given a name. The storm becomes more organized, and spiral rainbands develop around a more defined center.

4. **Hurricane**: At [wind speeds](https://scijinks.gov/hurricane/) of 74 mph (119 km/h) or higher, the system becomes a full-fledged hurricane. A distinct eye forms at the center, surrounded by a violent eyewall where the most severe weather occurs.

## The science behind hurricane intensity

Hurricanes derive their energy from warm ocean waters and moist air. The process [involves](https://nhmu.utah.edu/sites/default/files/attachments/All%20About%20Hurricanes.pdf) a heat engine mechanism where warm, moist air rises from the ocean surface, leading to condensation as it cools at higher altitudes. This condensation releases latent heat, which fuels the storm's updrafts and strengthens the hurricane.

The Earth's rotation causes the [Coriolis effect](https://archive.org/details/NasaSciFiles-HurricaneEnergyAndCoriolisEffect), which imparts a spin to the storm system. This effect is responsible for the counterclockwise rotation in the Northern Hemisphere and clockwise rotation in the Southern Hemisphere. Additionally, the low atmospheric pressure at the hurricane's center draws in surrounding air. The pressure difference between the center and the periphery generates strong winds as air moves toward the center and rises.

## Climate change and hurricane intensity

Recent studies have shown a concerning trend in hurricane behavior linked to climate change. Hurricanes are now more likely to undergo rapid intensification — a significant increase in wind speed within a short period, typically 24 hours. For example, Hurricane Michael in 2018 [intensified](https://en.wikipedia.org/wiki/Hurricane_Michael) from a Category 2 to a Category 5 storm in less than 36 hours before making landfall in Florida.

While the total number of hurricanes may not have increased significantly, there is [evidence](https://www.noaa.gov/news-release/noaa-predicts-above-normal-2024-atlantic-hurricane-season) suggesting an uptick in the frequency of major hurricanes (Category 3 and above). A study published in Proceedings of the National Academy of Sciences in 2020 found that the proportion of Category 4 and 5 hurricanes has increased over the past four decades.

Warmer sea surface temperatures provide more energy for hurricanes, leading to higher maximum sustained wind speeds. According to the National Oceanic and Atmospheric Administration (NOAA), for every 1°C increase in sea surface temperature, the potential wind speed of hurricanes [can increase](https://www.natureworldnews.com/articles/58330/20230909/global-impact-extreme-weather-events-climate-change-intensify-frequent-hurricanes.htm) by up to 5%.

Moreover, warmer air can hold more moisture, leading to higher precipitation levels during hurricanes. Studies have shown that hurricane-associated rainfall rates [are expected](https://www.cbsnews.com/news/climate-change-may-make-extreme-hurricane-rainfall-five-times-more-likely-study-says/) to increase by about 7% per degree Celsius of global warming, as per the Clausius-Clapeyron relation.

Some research [suggests](https://www.npr.org/2018/06/06/616814022/hurricanes-are-moving-more-slowly-which-means-more-damage) that hurricanes are moving more slowly, which can exacerbate flooding by allowing storms to dump more rain over a single area. Hurricane Harvey in 2017 is a notable example, stalling over Texas and causing catastrophic flooding.

## Fascinating hurricane facts

Hurricanes are truly remarkable phenomena. The largest tropical cyclone on record was Typhoon Tip in 1979, which had a [diameter](https://www.scientificamerican.com/article/earths-strongest-most-massive-storm-ever/#:~:text=Besides%20having%20unsurpassed%20intensity%2C%20Super,New%20York%20City%20to%20Dallas.) of approximately 1,380 miles (2,220 kilometers) — nearly half the size of the continental United States. These storms are also energy powerhouses; a mature hurricane [can release](https://www.iii.org/fact-statistic/facts-statistics-hurricanes) heat energy at a rate equivalent to exploding a 10-megaton nuclear bomb every 20 minutes.

The eye of a hurricane, ranging from 5 to 40 miles (8 to 65 kilometers) in diameter, presents a stark contrast to the surrounding chaos. Despite the calm conditions within the eye, it is surrounded by the eyewall, where the most violent winds and intense rainfall occur.

Tropical storms and hurricanes are named according to a predetermined list maintained by the World Meteorological Organization. If a season exhausts the list of 21 names, additional storms are named using a supplemental list — a practice [updated](https://www.foxweather.com/weather-news/no-more-greek-alphabet-heres-what-happens-if-we-run-out-of-hurricane-names-this-year) in 2021 to replace the previous use of the Greek alphabet.

The economic impact of these storms can be staggering. Hurricane Katrina in 2005 [remains](https://www.iii.org/fact-statistic/facts-statistics-hurricanes) one of the costliest hurricanes in U.S. history, causing an estimated $125 billion in damage (adjusted to 2021 dollars). It also resulted in over 1,800 fatalities, highlighting the severe human cost of such disasters.

## Predicting and monitoring hurricanes

Advancements in technology have significantly improved hurricane forecasting. Geostationary satellites like GOES-16 provide continuous monitoring of tropical cyclones, offering high-resolution images that help meteorologists track storm development and movement. Specialized aircraft, known as hurricane hunters, fly directly into hurricanes to collect critical real-time data on wind speeds, pressure, temperature, and humidity.

Sophisticated numerical weather prediction models, such as the Global Forecast System (GFS) and the European Centre for Medium-Range Weather Forecasts (ECMWF), use vast amounts of data to predict hurricane paths and intensities. Ensemble forecasting — running multiple simulations with slightly varying initial conditions — helps estimate the range of possible outcomes.

A network of ocean buoys and Argo floats collects data on sea surface temperatures, salinity, and currents, which are essential inputs for forecasting models. Recent research has also identified a connection between atmospheric Kelvin waves — large-scale waves in the tropical atmosphere — and hurricane formation. Understanding this relationship could improve long-range forecasting of hurricane activity.

## The impact of hurricanes

Beyond the meteorological fascination, it's crucial to recognize the profound human toll of these storms. Studies published in the American Journal of Epidemiology [have shown](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9710380/) an increased incidence of cardiovascular events, such as heart attacks and strokes, among populations affected by hurricanes. The stress and physical exertion associated with evacuation and disaster response contribute to these health risks.

The psychological impact of hurricanes can be long-lasting. Survivors [may experience](https://www.ncei.noaa.gov/news/hurricanes-take-heavy-toll-mental-health-survivors) post-traumatic stress disorder (PTSD), anxiety, depression, and other mental health issues. Access to mental health services is a critical component of disaster recovery efforts.

Hurricanes can cause significant economic disruption, affecting local businesses, agriculture, infrastructure, and even global supply chains. For instance, Hurricane Harvey [disrupted](https://www.forbes.com/sites/ellenrwald/2017/08/28/hurricane-harvey-impacts-crude-oil-and-gasoline-what-you-need-to-know/) oil and gas production in the Gulf of Mexico, leading to fluctuations in global energy markets.

Severe hurricanes can lead to long-term displacement of populations. Following Hurricane Maria in 2017, an [estimated](https://edition.cnn.com/2018/12/19/health/sutter-puerto-rico-census-update/index.html) 130,000 people left Puerto Rico for the mainland United States, impacting demographics and economies in both regions. Vulnerable communities, including low-income populations and marginalized groups, often suffer disproportionately from hurricane impacts due to factors like inadequate housing, limited access to resources, and pre-existing social inequalities.

## Looking to the future

As our climate continues to change, understanding and predicting hurricanes becomes increasingly critical. Efforts to improve resilience against these powerful storms involve multiple strategies. Ongoing research into the links between climate change and hurricane behavior is essential, as enhanced understanding can inform policy decisions and adaptation strategies.

Investing in resilient infrastructure — such as elevated buildings, storm surge barriers, and improved drainage systems — can mitigate the physical damage caused by hurricanes. Strengthening early warning systems ensures that populations receive timely and accurate information, enabling effective evacuation and preparation.

Public education campaigns and community engagement are vital for fostering preparedness. This includes disaster drills, emergency kits, and evacuation plans. Governments and organizations must integrate climate projections into urban planning, building codes, and resource allocation to reduce vulnerability to hurricanes.

The key takeaway is that while hurricanes are natural phenomena, human activities are altering their characteristics in ways that pose new challenges for coastal communities and beyond. As we face this evolving threat, continued investment in climate science, improved infrastructure, and community preparedness will be crucial in mitigating the impacts of these colossal storms.
