What is the abnormal weather phenomenon this year 2022? Why is it so abnormal? Specifically these are the three reasons!

Recently, the weather in many parts of my country has been rather abnormal. It is the hot summer season, but some areas have experienced rain and snow, so much so that we are still wearing coats and cotton-padded jackets. So what is the reason for the abnormal weather in 2022? Why is it so abnormal? Specifically these are the three reasons!

1. What is the abnormal weather phenomenon this year 2022?

The abnormal weather in 2022 is an abnormal phenomenon, mainly caused by the La Niña event and abnormal tropical sea temperatures. Because according to the forecast of my country's Climate Center, the second wave of my country's double La Niña phenomenon is expected to end in spring, but according to data forecasts released by US climate experts, signs of the third wave of La Niña phenomenon have appeared, so the summer of 2022 may be affected by the La Niña phenomenon. It is expected that my country's climate conditions will deviate in the later period, with droughts and floods occurring simultaneously, and regional and periodic drought and flood disasters being obvious. There will be more extreme weather, with the rainy areas mainly concentrated in the northern region.

According to the recent weather forecast, it is expected that the rainfall will expand eastward rapidly on the 19th. Places such as the eastern part of the southwest region, Jiangnan, and South China will experience light to moderate rain from west to east. Among them, central and southern Jiangnan, northern South China, Guizhou and other places will experience heavy rain and local torrential rain, so everyone should take precautions in advance.

2. Why is the weather so abnormal this year? 2022

The abnormal weather this year is mainly caused by the periodic fluctuations in atmospheric circulation and abnormal tropical sea temperatures. Many people think it is related to the Tonga volcano, but it is not. The detailed reasons why the weather in 2022 is so abnormal are as follows:

The specific reason why the weather in 2022 is so abnormal is that the atmospheric circulation fluctuates periodically.

Recently, the periodic fluctuations in the westerly belt circulation in the mid- and high-latitudes of Eurasia have been relatively large, resulting in more frequent cold air activities. Among them, the periodic strengthening of the Ural Mountain blocking high pressure and the East Asian trough has triggered three cold wave weather processes since late April.

The specific reason why the weather in 2022 is so abnormal is the impact of the La Nina event.

Affected by the La Niña event, the mid- and high-latitude circulation in Eurasia has a large longitudinal direction and obvious periodic fluctuations. The frequent activities of cold air have affected my country's climate background conditions.

The weather in 2022 is so abnormal this year. The specific reason is that it is the end of spring and the beginning of summer.

In late spring and early summer, the precipitation in central and eastern my country gradually decreases, causing the cold air to warm up quickly during the intervals.

Summary: This year's abnormal weather is an abnormal phenomenon, mainly caused by periodic fluctuations in atmospheric circulation and abnormal tropical sea temperatures. This situation is expected to continue for some time. For example, on the 19th, the rainfall will expand eastward rapidly, and some areas will experience heavy rain and local torrential rain.
