What does it mean that there could be a triple La Ni a event this winter?

This means that this year's winter will be more unusual, different from previous winters, and we need to prepare for it.

If that's the case, I think this winter will be particularly cold. The climate will be more abnormal.

This means that the weather is likely to cool down this year, and the cold air is likely to last longer.

La Niña is actually an anomaly in the central and eastern Pacific Ocean, where the water suddenly cools, and at this time, it will face widespread precipitation or typhoons.

This phenomenon is a gradual cooling of temperatures in the eastern and central Pacific Oceans.

If the "La Niña" phenomenon forms this winter, it will definitely bring a lot of inconvenience to our lives and production. For example, the specific situation is roughly as follows:

First, there is a high probability that this year's winter will be cold.

Due to the formation of the "La Niña", it is possible that the whole winter will be a "La Niña event", which means that the temperature in our country may be cold this winter. And the colder winter means that there will be a cold spell. Once a cold wave comes, not only people's travel will be affected, but also agricultural food production will be affected, such as some crops are frozen to death, or extreme weather causes some meteorological disasters that cause some unpredictable agricultural losses.

Second, this year may face a situation of "drought in the south and flooding in the north".

After the occurrence of the La Niña phenomenon, it can be said that there are many more tropical cyclones that have landed in China than in previous years, which is likely to directly cause a situation of "drought in the south and flooding in the north". Take a look at our country this year.

In September and October, there was a lot of rain in Zhengdi, which even caused great floods, but the rainfall in the south was reduced. If a "La Niña" event is formed in winter, this situation of "drought in the south and flooding in the north" may be aggravated. It can be seen that the "La Niña" phenomenon will bring a lot of inconvenience to our lives this winter.

Third, people need to pay more attention to climate-related changes.

Although there is a possibility of a "La Niña event" this winter, we can take some precautions in advance, so that if there is a cold wave or other extreme weather, at least we can respond to the changes. It is important to know that when floods and droughts go hand in hand, they can have a huge impact on our electricity. In addition, when extreme weather occurs, our traffic roads may also be blocked.

Therefore, I hope that people can pay more attention to climate change, do a good job of relevant self-protection measures, and do not let this abnormal climate phenomenon affect our normal life, work and study.

It may make the weather very cold, people's lives are more difficult, a lot of farmers and crops will die, the winter is relatively long, there will be a lot of precipitation.

The cooling situation is particularly serious, there will be drought on the east coast of the Pacific Ocean, and then it is easy to have floods in the west, and there will be abnormal weather or typhoon weather in coastal cities, and there will be heavy rain and strong winds in Xiangque, which may lead to natural disasters.

It will cause the global temperature to drop, produce extremely bad weather, affect people's lives, affect the survival of animals, and may cause a large number of animals to die.

This phenomenon will lead to an imbalance in the ecological environment, and Li Qiaoqin will also affect the climate, and will also affect the normal life of the residents. It can also affect the temperature. It may also cause some disturbance in extreme weather.

It will make the temperature lower, let people go out less, it will affect the plants, it will affect the animals, it will affect the economy, and this winter will definitely be very cold.

This means that winters can become exceptionally cold, with varying degrees of drought and flooding in many places。The World Meteorological Health Organization (WCE) has released a new set of data that publicly shows that La Niña events have been going on for a long time around the world, and the point is that this is likely to continue for a longer time, and this is the first triple La Niña event in the 21st century.

First of all, many people may not have heard of La Niña events, but they are mainly referring to a special weather condition that will cause persistently low temperatures in the eastern and central equatorial Pacific Oceans. Don't think that this has nothing to do with you, or even that doing so will slow down global warming, because things are far from being as simple as we think. The climate is no small matter, and sometimes this special situation affects the entire planet, and none of us are immune.

Second, La Niña events can have a direct impact on precipitation and temperature. Under normal circumstances, there may be two consecutive La Niña events in the Northern Hemisphere in a winter, but three in a row is indeed rare, and the worsening drought situation in many parts of Africa is very likely to be related to the La Niña event, which is very consistent with its characteristics. Australasia and Southeast Asia have received much more precipitation than in previous years, causing severe natural disasters.

Finally, whether it is drought in Africa or precipitation in Southeast Asia, it will directly affect the safety of millions of people, potentially leaving them homeless, displaced and starving. La Niña could also lead to an increased risk of wildfires, hurricanes in the Pacific Ocean, and even slightly higher sea levels than the average of previous years, all of which are threats to humanity. Even if global warming can be temporarily delayed, there will be no reversal trend, so we must not take chances, and we must protect the environment, otherwise everyone may be attacked by nature.

According to reports, there is a high probability of a triple La Niña event in our country this winter. This situation means that our country is likely to experience severe cold or abnormal weather such as rising temperatures this winter.

What is a La Niña event?

La Niña refers to a phenomenon in which the waters of the eastern equatorial Pacific Ocean are abnormally cooling, warming more than normal, or occurring at the same time as El Niño. During the La Niña event, the El Niño phenomenon will occur and the extreme weather and climate events will occur frequently, such as the severe cold in the winter of 2008, the super typhoon in 2011, and the tropical storm in eastern India, Indonesia and other tropical regions in 2015. <>

What are the factors that affect the weather and climate?

Atmospheric circulation, ocean, land surface and meteorological elements are important factors that affect weather and climate. The thermal properties of the two plates, both on land and sea, are very different, which also makes the two regions very different. For example, the earth's atmosphere is composed of the earth's crust and oceans, and there are many different types of oceans and lands on the earth's crust, and the atmosphere influences and interacts with each other.

How to respond to a La Niña event?

In response to the La Niña incident, Japan has already begun to respond to the incident. In the medium and long term, the impact on the climate system is mainly carried out in the following ways: first, in winter, it is necessary to pay close attention to the temperature change trend and the ocean circulation situation to monitor the impact of "La Niña events" on the climate; The second is to strengthen the observation and research of global change through observation, research and simulation of relevant meteorological observation stations, so as to grasp the trend of climate change; the third is to improve the accuracy of the climate model and other scientific means; Fourth, we should improve our ability to prevent disasters by strengthening our awareness of disaster prevention and mitigation.

In short, it is necessary to further strengthen and improve the national climate monitoring and early warning system, continuously improve the monitoring and early warning capabilities, improve the ability and level of data processing and analysis, release early warning information and emergency plans in a timely manner, and strengthen the technical reserves and capacity building of extreme event forecasting and early warning. Strengthen exchanges and cooperation with international experts to continuously improve the comprehensive disaster response capacity. Adjust the focus of disaster reduction efforts and response measures according to the changing dynamics of La Niña and the results of monitoring and early warning.

This means that this year is likely to be cold, and you should be prepared for a cold winter. Because the hotter the summer, the colder the winter.

It's a good thing and maybe something new about the world, really great to exist.

La Niña refers to the phenomenon of unusually cold at the equator, which could mean super cold this winter.

This is a different change in nature, so this nature also gave a very bad result.

La Niña events are climate phenomena in which the sea surface temperature in the eastern equatorial Pacific Ocean is abnormally cold and lasts for a long time.

During the La Niña event, the sea temperature in the western and northern Pacific Ocean showed obvious easterly and alkaline background, and the sea temperature in the eastern and southern equatorial Pacific Ocean was higher than that in the same period of the year, and the sea surface salinity increased significantly. During this period, a regional persistent El Niño event occurred, known as a La Niña event. Its impact is mainly reflected in the lack of typhoons, precipitation and ocean warming in the central and eastern parts of China.

In general, La Niña events cause heavy rainfall and flooding in the tropics; The disastrous weather caused by the formation of tropical cyclones will also cause related meteorological disasters, affecting agricultural production in southwest China and southern China. Therefore, La Niña is an important natural phenomenon in the process of global climate change.

What is La Niña?

La Niña is a climate phenomenon in which the sea temperature in the coastal waters of the equatorial Pacific Ocean is abnormally cold and unusually cold in the short term, resulting in abnormally cold sea water temperatures in the eastern and southern equatorial Pacific Oceans. Unlike El Niño events, La Niña events are persistent events that last longer than they do at a specific latitude. La Niña events last for a long time and do not change the overall climate situation, and are a climate phenomenon with cold winters or warm summers.

It usually appears in winter or spring. It has the characteristics of long duration, high intensity, wide range of influence, and long duration.

La Niña's impact.

La Niña is thought to cause sea surface temperatures to be above low in the Pacific Ocean, and above 10 in the western Pacific. The average sea surface temperature in most parts of China is higher than that of the same period in normal years, and the average sea temperature near the equator is. In this way, we can define a La Niña event as a more obvious regional persistent El Niño that has occurred this winter.

La Niña events, which have been going on for a long time, are likely to continue until the end of the year or beyond, and will be the first "triple" La Niña event in the 21st century, i.e., three consecutive La Niña winters in the Northern Hemisphere.

Refers to the phenomenon of persistently unusually cold sea surface temperatures in the eastern and central equatorial Pacific Ocean. This phenomenon slows down global warming, but extreme weather occurs.

A La Niña event is the extreme cold on the surface of the ocean.

The National Climate Center has released the latest edition of La Niña Climate Trends**. According to **, there is a 70% to 80% probability of a La Niña event this winter, and the event will continue until next spring. As it stands, triple La Niña events will continue to occur over the next three months.

Some experts believe that such incidents may continue until early next year.

La Niña refers to an abnormally high sea surface temperature in the equatorial Pacific Ocean. It is generally believed that the occurrence of La Niña phenomenon occurs when the ocean surface temperature in the central and western Pacific Ocean is 1 2 times lower than the average for the same period of the year in June and September every year. When La Niña appears, it will last for a longer period of time before gradually weakening and disappearing.

It is generally believed that when the surface temperature of sea water is lower than -2, La Niña phenomenon occurs; La Niña occurs when the surface temperature of sea water is higher than -4 or greater than -2. And according to the World Meteorological Organization's definition of La Niña climate class (VI):

When the surface water surface temperature of one western Pacific Ocean is more than 1 lower than that of the other ocean, it is called a cold zone; A warm zone is called a warm zone when the surface water surface temperature of one eastern Pacific Ocean is more than 1 lower than that of the other ocean. That is, La Niña is a climatic phenomenon, but not a standalone climatic phenomenon. In addition, when La Niña becomes a climate cycle, a series of related climate phenomena occur.

This anomaly in the Arctic often manifests itself as a "small equator" type of abnormal weather process, which often affects climate change on a global scale. There have been four more notable La Niña events in the past decade: the last in September, October, November 2014, and mid-January 2016, both over the east-central equatorial Pacific.

However, this anomaly may persist or worsen in the future. However, due to the fact that various factors such as El Niño and La Niña are still affecting the trend of global climate change, the possibility of a large-intensity La Niña event in the coming period cannot be ruled out.
