What is the abnormal weather this year?

-The abnormal weather in 2022 is an abnormal phenomenon, mainly caused by La Nina events and tropical SST anomalies. According to the forecast of China Climate Center, the second Polanyina phenomenon in China is expected to end in spring, but according to the data released by American climate experts, the third Polanyina phenomenon appears, so it may be affected by La Nina phenomenon in the summer of 2022. It is predicted that the climate in China will deviate in the later period, and there will be obvious regional and staged droughts and floods. Extreme weather and rainy areas are mainly concentrated in the northern region.

What is the reason for the abnormal weather this year?

The weather in 2022 is so abnormal this year. Specific reason 1: the atmospheric circulation fluctuates periodically.

Recently, the periodic fluctuation of circulation in the westerly belt of mid-high latitudes in Europe and Asia makes cold air activities more frequent. Among them, the blocking high pressure in the Ural Mountain and the periodic strengthening of the East Asian trough have caused three cold wave weather processes since late April.

The weather in 2022 is so abnormal this year. There are two specific reasons: the impact of La Nina incident. Due to the influence of La Nina event, the meridional circulation in the middle and high latitudes of Europe and Asia is relatively large, with obvious periodic fluctuations. The frequent activities of cold air have affected the climatic background conditions in China.

There are three reasons why the weather is so abnormal this year: late spring and early summer. Every year in late spring and early summer, the precipitation in the central and eastern regions of China gradually decreases, which makes the cold air heat up rapidly during the intermission.
