North and South will usher in temperature highs in the early stages of this week (March 10 to March 16), but with the active cold air, the weather will also usher in a turning point. In general, the weather changes drastically this week, with rain and snow gradually increasing, and temperatures rising and falling.

Meteorological Analyst Ouyang Yi: The weather this week can be said to be very changeable. Let’s talk about the temperature first. The large-scale heating of the two-day weekend will continue at the beginning of this week. Many floors in the north have been warmed up. At the same time, after temporarily getting rid of the rain in the south, the temperature will also usher in a significant rebound. The highest temperature in most parts of Jiangnan and South China will generally exceed 25 degrees, and the maximum temperature 20 degrees line will also be pushed to the southern area of ​​Hebei.

But the cold air is ready to go, and it is expected that two consecutive cold air will affect our country this week, with the main impact period lasting from Tuesday to Sunday. After the temperature peaks at the beginning of the week, the temperature in the central and eastern regions will decline all the way, and the cumulative cooling range will generally reach 8 to 12 degrees, and the maximum temperature 20 degrees line will also retreat from southern North China to South China again. By Friday and weekend, temperatures in various places will turn low again. The temperature fluctuates greatly, so everyone should pay attention to adjusting their clothes in time.

In addition to cooling, cold air will also bring about very annoying sandstorms in spring. March to May are the most frequent sandstorms in the north. It is expected that from Monday to Wednesday, there will be a sandstorm or severe sandstorm in the eastern part of the Northwest region, most of North China, northern Huanghuai and other places.

Cold air moves eastward and southward, and it will also bring rain and snow at the intersection of cold and heating airflows. It is expected that the rain and snow will gradually increase this week.

In the north, northern Xinjiang and northeastern regions will experience snowfall one after another. For the northeast, rain and snow will occur on Tuesdays, Wednesdays and two days on weekends, and by weekends, the snowfall range and intensity are not small. The rainfall in the southern region is relatively weak during the day from Monday to Tuesday, and some areas will be temporarily clear. From Tuesday night, the rainfall in the south will increase significantly. Until the weekend, the cumulative rainfall in central and southern Jiangnan and many places in southern China will exceed 70 mm, with heavy to heavy rain in some areas, and the rain will also be accompanied by strong convective weather.
