This winter may be a triple La Ni a event! For the first time in this century, what does this mean?

The occurrence of La Niña events will seriously affect the occurrence of droughts and floods around the world. It has the potential to increase the likelihood of flooding in Southeast Asia, increase the risk of drought and wildfires in the southwestern United States, and create multiple hurricane, cyclone, and monsoon patterns in the Pacific and Atlantic, as well as trigger climate change in other regions.

La Niña is an important feature of global climate change, and it refers to the ongoing interaction between El Niño and the Earth's surface and ecosystems. In recent years, there have been a number of La Niña events, and the intensity of La Niña has reached the "tipping point" of the year. According to the global climate system, there is a possibility of a "triple La Niña" event this winter.

Why is there a triple La Niña event?

Global climate** suggests that triple La Niña is more likely to occur this winter, reaching its strongest intensity since 2008. In recent years, the global SST has shown a strong seasonal fluctuation pattern, which is closely related to the changes in atmospheric circulation in the middle and high latitudes of the Northern Hemisphere under the background of global warming. According to the current trend, the temperature in the northern hemisphere decreases more in winter than in summer, resulting in an abnormal increase in the southern branch and the North Pacific SST, and then La Niña El Niño.

What is a "triple La Niña"?

From the perspective of the general trend of global warming, in recent years, extreme weather and climate events have many occurrences, high frequency and wide range of impact, which have had a huge impact on human production and life. According to the latest**, there is a possibility of a triple "La Niña" this winter. The occurrence of triple La Niña will cause the sea surface temperature in the eastern equatorial Pacific Ocean to be abnormally cold, and may even form a winter El Niño event.

According to the analysis of experts, the temperature in northern China has been low recently, and the southern part of China still needs to be vigilant against the trend of drought and flood disasters in the coming week. Some see La Niña as a signal of global warming and link it to rising carbon emissions, rising sea levels, acid rain, droughts, and more.

This winter may be a triple La Niña event! For the first time in this century, this means changing temperature and humidity patterns, exacerbating droughts and floods in different parts of the world.

This means that this winter will not be as warm as last year, which is good for the phenomenon of abnormal warming, and if it is generally cooler and colder, global carbon dioxide will also fall.

It means that this winter will be cold, the weather will be abnormal, and people will have to wear more clothes.

Under the synergistic influence of La Niña events and the Arctic Ocean, the cold air activities in China are likely to be strong this winter, so this winter is likely to be a cold winter.

World Meteorological Organization: A "triple" La Niña event is likely this winter!

The World Meteorological Organization (WMO) conducts ** current La Niña events in the polar states are likely to continue for 6 months. Current La Niña events, with the strengthening of trade winds, have strengthened La Niña event conditions in the tropical Pacific, affecting temperature and precipitation patterns, exacerbating droughts and delayed flooding in different parts of the world.

Will this winter be cold or warm?

Meteorological experts said that the temperature in the north and other regions this winter is lower than that of the same period in normal years, and extreme weather is very likely. In recent years, we can deeply feel that the summer is particularly hot, the winter is particularly cold, and the probability of extreme weather is gradually increasing, and the occurrence of La Niña phenomenon will also lead to a certain impact on global warming. Then there is a cold winter, affected by the La Niña phenomenon, this winter in most parts of the country windy weather is frequent.

Due to the high intensity of precipitation, it will cause secondary disasters such as farmland waterlogging, threatening agricultural production and traffic safety. The La Niña phenomenon will lead to anomalies in atmospheric circulation in the middle and low latitudes, and transport warm and moist water vapor to the eastern and southern parts of China, and increase precipitation in the central and eastern parts of China. Temperatures are on the low side, leading to droughts.

In particular, there will be heavy precipitation or periodic drought and frost damage in the arid areas of the north, which will seriously affect agricultural production, cause crops to be damaged, and bring large economic losses, which need to be paid great attention to.

How can we prevent the arrival of La Niña?

In winter, low temperatures, high humidity, low wind speeds, and low temperatures will reduce the oxygen content in the air and reduce respiratory immunity. Therefore, it is necessary to take measures to keep warm, exercise properly and increase the time for outdoor activities; When indoor air quality is poor, be sure to open windows or use humidifying equipment such as humidifiers to promote air circulation. The low temperature in winter has a huge impact on crop production and people's lives, and we should also pay attention to the La Niña phenomenon when it comes.

I think it's definitely a cold winter, because it's not winter yet, but it's already showing a cold spell.

If there is a triple La Niña, it means that this year's winter will be very cold, and the cold will last for a long time.

This year's cold winter is definitely very cold, and this kind of winter will bring us a chill, so we must pay attention.

According to the news released by the National Climate Center, since July this year, the sea surface temperature in the eastern equatorial Pacific Ocean has continued to decline, so it will enter a La Niña state in October, and in winter, a weak to moderate La Niña event will be formed, which has attracted the attention of many friends in the face of this situation, and the World Meteorological Organization has also launched a notice on such a thing, and the impact of this event may be delayed to the second yearIn the face of this situation, many people feel very curious, what is the La Niña incident all about?

For such a meteorological term, there are many people who feel that it is a relatively normal La Niña event that cannot be understood, which refers to a cold water phenomenon in which the surface temperature of the equatorial eastern Pacific Ocean has been cold on a large scale, and the intensity and time are also relatively long, according to the statistics of the National Climate Center, it can be found that after such an event, the probability of cold in China in the winter of reeds will reach about 70%. Therefore, this also leads to lower winter temperatures in the central and eastern parts of China this year than in previous years.

However, we need to pay attention to the fact that not all La Niña events will lead to low temperatures in China's winter, which is also caused by different circumstances, and the impact on China's climate is mainly from the two aspects of temperature and precipitation. Tropical and tropical-rich regions are also affected by such events, causing precipitation to begin to decrease.

Through the above understanding, it can be found that after such a situation occurs, the overall impact on China's climate is relatively obvious, so in the face of this situation, we also need to have sufficient psychological preparation.

At the equator, the temperature in the eastern Pacific Ocean is unusual, with a wide range of temperature drops. The phenomenon of cold water is called a La Niña event.

Refers to a weather phenomenon in which the water temperature drops abnormally near the equator, which is very dangerous and affects the global climate.

This refers to the southeast trade winds, which then blow the hot waters to the west of the Pacific Ocean, a phenomenon known as this phenomenon.

That's some El Niño opposite. In some places, the sea surface temperature can be said to have a very significant decrease.
