In the morning it was still sunny.The weather in Hangzhou is only a sudden change, but in the eastern part of my country, the situation of large-scale cooling and precipitation has been determined. After many days of high temperature weather, the “cold spring cold” seems to be really coming (video).

It can be obtained from the high-definition visible light satellite cloud image taken by Fengyun-4.A large-scale rain cloud in the eastern part of my country is particularly conspicuous, which is a rain-snow cloud system formed by the entanglement of cold air and warm and humid air flowing from the south.
In Anhui, Jiangsu and other places, thunderstorms have already occurred in some areas affected by it this morning.
The impact of this cold air on the areas south of the Yellow River is actually not great, but at the turn of winter and spring, especially after experiencing a large-scale and long-term warm weather, it is still worthy of vigilance.
In the process of the stronger cold air going south, the cold and warm air with comparable strength will face it fiercely, which may trigger large-scale convective activities in the central and eastern regions of my country, accompanied by rainfall in many places to cool down.
Supercomputer predictions believe that this week, the fluctuations in the westerly belt will send cold air southwards in the central and eastern regions of my country, and the 850 hPa 0 degree freezing line will once again be greatly advanced to the south of the Great Wall.
According to the forecast of the Central Meteorological Observatory,From 8:00 on March 16 to 8:00 on March 17, there were moderate to heavy rains in parts of southern North China, most of Huanghuai, Jianghuai, eastern Jianghan, northern and western Jiangnan, and eastern Guizhou. Among them, central Anhui, eastern Hubei, and central Hunan There are heavy rains (50-80 mm) in parts of the north and other places.
There are winds of magnitude 4 to 6 in parts of the southern Xinjiang Basin and eastern parts of Xinjiang, northern Qinghai, and northern Henan.
During this rainfall,Most of the central and eastern regions will have a cooling of 4 to 8 degrees, of which local cooling in Henan, Anhui and other places can exceed 10 degrees.
For example, in Zhengzhou, Henan, it is expected that the minimum temperature will drop from above 10 degrees to about 0 degrees this week, and the maximum temperature will drop directly from 25 degrees to about 5 degrees. It is not ruled out that a cold wave warning will be issued.
