The strong convective precipitation process in the south is diurnal and diurnal! The potential in the north weakens with time

People's Voice of the World, April 22, Beijing Express In the blink of an eye, the traditional 24 solar terms of "Gu Yu" have arrived. This week's (April 22-28) national weather stage, experts believe that cold and warm air is still active, during which the trough from Lake Baikal to Mongolia will continue to throw out cold air, and at the same time, the warm and moist air flow north of the subtropical high will continue to move north. As a result, it will remain rainy in the south during the week. And under the warm and humid air flow pulse, there are also obvious rainfall and convection processes. The temperature in the north is fluctuating, and it may drop significantly after hitting a new high from the 25th to the 26th. In addition, along with the activity of cold air, there may also be wind-blown sand in the north.

Experts said that the monitoring data shows that from the afternoon to the evening of today (22nd), there were strong convective weather in Shaanxi, Shanxi, Hebei, Beijing, Tianjin, Guangdong, Fujian and other places; According to the analysis of the latest meteorological data, from tonight to tomorrow (23rd), the strong convection area is still distributed in the north and south. During this period, the northern convection region moved eastward with the upper-air trough, and the southern convection region was mainly located along the coast of South China, where the corresponding cold and warm airflow converged. For this reason, the Central Meteorological Observatory continued to issue a yellow warning for severe convection tonight.

Industry insiders stressed that it is not difficult to find out that as experts say, judging from the current forecast, the convection potential in the north will decline during the day tomorrow, and the convection will mainly be from tonight to tomorrow morning. In South China, the convective potential is relatively high day and night. In addition, there is more abundant water vapor in coastal areas, and severe convection is manifested in the form of short-term heavy rainfall more than thunderstorms and strong winds, and the impact of short-term heavy rainfall is also greater.
