People's Voice of the World, April 13, Beijing Express In the blink of an eye, the "Qingming" of the traditional 24 solar terms has arrived. In the national weather stage this week (April 8-14), in the opinion of experts, the rainfall in the south first decreased and then increased, mainly on the 11th and 14th, and the core area was in the south of the Yangtze River. The northern region was affected by two shortwave troughs from the 8th to the 10th, and there was also weak precipitation. In addition, from the 12th to the 15th, a deeper upper-air trough moved eastward to cooperate with the Mongolian cyclone, resulting in precipitation, cooling, strong winds, and sand and dust in the north. Therefore, the temperature in Northeast China and North China fluctuates greatly.

Experts said that monitoring data showed that from yesterday (12th) to this morning (13th), northern Xinjiang was affected by cold air, and there was a wide range of rain and snow. At the same time, parts of the northeast and south of the country ushered in thunderstorms due to the active warm and humid airflow. During this period, the rainfall in the south can be subdivided into two parts: one is the convective rain from southern Hunan, southern Jiangxi, and Fujian from yesterday afternoon to the evening; the other is the convective rain from southeastern Chongqing to northern Hunan from last night to this morning; among them, there are hail in the northwest of Hunan.

According to experts, according to the analysis of the latest meteorological data, the current convection in northern Hunan will continue to move eastward in the future; as a result, from today to tomorrow morning (14th), northeast Hunan, southeastern Hubei, central and northern Jiangxi, southern Anhui, western Zhejiang, and northern Fujian may have heavy rain - heavy rain localized heavy rain. In addition, there may be short-term heavy rainfall of 20-40 mm in a single hour. At the same time, convective rainfall also appeared in Shaanxi and Shanxi in the north, as well as in the Hetao area of Inner Mongolia today.

It is worth noting that industry insiders stressed that it is not difficult to find that as experts say, the northward movement of warm and humid airflow will slow down some bends in the south of the Yangtze River, so it will lead to significant rainfall, and because the atmosphere is unstable, it will also trigger convection. Some of the warm and humid airflow will move northward, and convective rain will also be triggered when it encounters cold air moving eastward. Ningxia in particular, there is also convective potential today; however, the water vapor conditions are not good; therefore, the precipitation forecast basically does not give rain; such an unstable atmosphere, superimposed by the influence of strong winds, is conducive to blowing up sand and dust; but it is not ruled out that some "muddy rain" will rain from thunder.
