The triple La Ni a may reappear, what will be the portents of this winter?

The occurrence of La Niña will change the climate, and the sea surface temperature in the eastern equatorial Pacific Ocean will continue to be abnormally cold, and the Siberian sea ice will continue to be low.

As the subtropical high continues to be strong, the temperature in the northern region will continue to be high, which will have an impact on the temperature change in winter. Judging from the current climate trend, the eastern sea area of China will maintain a strong westerly wind and low temperature pattern this winter, which will have an adverse impact on the winter and spring precipitation in China.

1. The SST in the eastern equatorial Pacific Ocean continues to be abnormally cold.

In the context of climate warming, the impact of "El Niño" events is becoming more and more obvious. In the region of cold sea surface temperature in the eastern equatorial Pacific Ocean, the sea water temperature in the western and central eastern parts of the Northwest Pacific Ocean is abnormally colder than that in the same period of the year. In winter, the impact of sea surface temperature (SST) on China in the eastern equatorial Pacific Ocean weakened.

Since October, most of the central and eastern seas have experienced a weather process of more than 8 cooling amplitudes or low temperature days less than 10 days.

2. The sea surface temperature in East Asia has dropped significantly.

Since the beginning of this year, the SST in East Asian seas has generally been lower than that of the same period in normal years, and there is an obvious pattern of "weak, strong and weak" in November, which indicates that the persistent high temperature in East Asia will weaken this winter, which will have an adverse impact on China's winter precipitation. Generally speaking, the degree of cold and warm in the northern sea will have a direct impact on the winter precipitation in China, but the impact of this La Niña event on East Asia is more direct.

3. Siberian sea ice continues to be low.

This year, the sea ice area in Siberia is 60% less than that of the same period in normal years, and the sea ice area in northern China is decreasing due to the abnormal polar sea ice events, among which the sea ice area in eastern Russia, Siberia and northern Kazakhstan is 68% and 68% lower than that in the same period of normal year, respectively. At present, the temperature in northern China is higher than that of the same period of the year and the same period of the previous year, but the sea ice area of Siberia is still low.

The harbinger of this winter is the weather, the temperature will be very low, very cold, and there will be heavy winds and rains.

More La Niña events will have multiple impacts, such as increasing the likelihood of flooding in Southeast Asia, increasing the risk of drought and wildfires in the southwestern United States, and creating multiple hurricane, cyclone, and monsoon patterns in the Pacific and Atlantic Oceans, as well as triggering weather changes in other regions.

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.

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.

This phenomenon means that this winter will be colder and last longer, but this situation is not so absolute, because of the impact of global warming, triple La Niña events can also occur in a warm winterAccording to the current situation, it is not possible to determine what kind of climatic conditions this phenomenon will bring, we do not need to panic excessively, we just need to take defensive measures, if there is any news of abnormal weather, the official will also notify in advance, this situation is that we human factors can not interfere, we continue to pay attention to weather changes, do not believe all kinds of rumors on the Internet, all information is subject to the official data, do not spread false rumors, and do not deliberately create panic.

Since global warming, our climate conditions have undergone a lot of subtle changes, scientists are trying to find a new habitable planet, many people are also very concerned about climate change, La Niña events belong to professional terms, many of us will feel relatively unfamiliar when we see this word, because it is too professional to make people feel a little worried, so what is the La Niña event going on? A La Niña event is a phenomenon in which sea surface temperatures in the eastern and central equatorial Pacific Ocean remain unusually cold, and triple La Niña events are the case of successive occurrences of this climatic condition.

Generally speaking, the occurrence of La Niña events means that the temperature in winter is generally low, and the duration of winter will be extended, and continuous La Niña events have also occurred, but triple La Niña events are indeed very rare, and since the impact of each La Niña event is different, it cannot be said that La Niña events necessarily mean anything.

The impact of the La Niña event is multifaceted, in addition to the motivation to drop the temperature, there is also a possibility of increasing the probability of natural disasters, the specific situation is not very well understood, or to wait for further observation and analysis of the official, before that everyone needs to worry too much, this is not a problem that we can solve by worrying.

La Niña is the anti-El Niño phenomenon, El Niño phenomenon is the embodiment of global warming, generally the appearance of El Niño indicates that the winter is not cold, and the climate is extreme, and the La Niña phenomenon is different, generally indicates a cold winter and abnormal climate, this kind of occurrence should normally be longer and earlier and colder in winter, and there may be extremely cold and cold wave weather.

La Niña is also caused by changes in the oceans, as the waters near the equator in the eastern Pacific Ocean are abnormally cooling, causing the waters along the western Pacific continent to rise, and the rising waters allow moisture to enter the continents. The monsoon brings moisture inland, causing more rain in the interior and more rain in the north, while the climate in the coastal and southern areas is hot and rainless, resulting in drought in the south and flooding in the north, which is the main manifestation of La Niña. La Niña phenomenon is terrifying, this is not to say horror, but to say that the emergence of La Niña is not much strange to now, La Niña does not mean that extreme weather will occur, it can only be said that there is a high probability of more serious and bad weather, from the perspective of the national climate in 2022, we can basically determine that La Niña has formed.

In addition, in 2022, the climate in South China was abnormally hot and very dry and rainless, resulting in extreme drought, while Henan and Shanxi in Shaanxi Province experienced severe floods. This just indicates the impact of La Niña, and the cold weather in 2022 also came early, and it was relatively cold, which also proves that La Niña has basically been confirmed. As for the climate in the future, it is difficult to say how it will develop, from the perspective of La Niña, there is a high probability that the winter is cold, and there is a certain probability of abnormal extreme weather, but these are not said to happen at all, just some speculation, after all, the weather changes anytime and anywhere, and it will not say how it will be, and no one can guarantee how the weather will change.

Summary: Even experts are actually not sure, can only be inferred through some details of changes, these conclusions are just for some reference, can not say that it will be so, can not say that what will happen, so the weather behind the climate change is very large, any direction of development is possible, just like last year said that the cold winter was cold, but in the end it was only the first half of the cold and the second half of the warm, that is to say, ** is not necessarily accurate.

A La Niña event is a phenomenon in which sea surface temperatures in the eastern and central equatorial Pacific Ocean remain abnormally cold. The impact of each La Niña event is different, depending on the intensity of the event.

Overall, a three-year La Niña event is indeed very rare, and its occurrence temporarily slows the rise in global temperatures, but does not stop or reverse the long-term trend of global warming.

This means that this year's winter will be particularly cold, and the cold will last for a long time.

According to the latest data, the long-lasting La Niña event is very likely to continue until the end of this year or beyond, that is, the first "triple" La Niña event in the 21st century, so what does the "triple" La Niña mean, and will this year be a cold or warm winter?

La Niña refers to a phenomenon in which sea surface temperatures in the eastern equatorial Pacific Ocean continue to be abnormally cold over a wide area. When sea surface temperatures persist to be unusually cold over a wide area, La Niña appears. From August 2020 to the present, the sea surface temperature in the equatorial eastern Pacific Ocean has been in a low state, especially in the autumn and winter of 2020, the autumn and winter of 2021, and the side ridge of this autumn and winter

However, the "triple" La Niña event does not accumulate year by year, and concentrates on "big moves" in the third year, so it does not mean that the climate impact will double, although it has a cumulative effect to a certain extent.

Although La Niña is more likely to have a colder winter, it doesn't mean that there will be a cold winter.

The National Climate Center predicts that the intensity of cold air affecting China this winter is generally weak, and the temperature in most parts of the country is close to the same period of the year or high, which means that it is unlikely that there will be a strong cold winter. However, the phased characteristics of temperature change are obvious, with the first winter being warmer and the latter winter being colder. 2022

From December to mid-January 2023, the intensity of cold air affecting China is weak, and the temperature in most parts of the country is higher than that of the same period in normal years; From late January to February 2023, the intensity of cold air gradually strengthened, and the temperature in most parts of central and eastern China was close to or low in the same period of the year. Phased heavy cooling and heavy snowfall may occur in the northern part of Northeast China and the eastern part of Northwest China, and periodic low temperature rain, snow and freezing weather may occur in the southern part of Central China and the southeast of Southwest China. There is a high possibility of drought in summer, autumn and winter in most parts of the southern part of the Yangtze River.

In the context of intensifying climate warming, temperature fluctuations will become larger and larger, and La Niña events will increase the probability of extreme abnormal weather events. Therefore, whether it is a cold winter or a warm winter, it is necessary to pay special attention to the phased severe cooling and severe cold weather. Zhou Bing said that this year, there may be a period of low temperature, rain, snow and freezing weather in the southern region, and it is necessary to prevent its adverse impact on transportation, electricity and agricultural production.
