Sichuan's large-scale rain and snow model started, and the temperature plummeted.

The large-scale rain and snow pattern in Sichuan started from 65438+February 25th.

On the afternoon of February 25th, 65438, from the cloud image of Fengyun-4 high-definition visible light satellite, although there are still many clear sky areas in the central and eastern regions of China today, the scope of clear sky areas is obviously reduced compared with that before the comparison.

So there are more cloudy places today, and even many places have begun to rain or snow.

This is the beginning of the change of weather situation in China. With the increase of water vapor entering our country again, the rain and snow weather will increase obviously, and the intensity of rain and snow is not weak in some places. From February 27th, 65438, a wide rain and snow front will be drawn from Yunnan, Guizhou, Sichuan and Chongqing to the Yangtze River estuary, and the boundary between rain and snow will be pushed southward significantly. There may be sleet or rain turning to snow or other solid precipitation weather in many places south of the Yangtze River.
