△ National Thunderstorm Gale or Hail Warning (Central Meteorological Observatory/Issue)
People's Voice of the World, April 17, Beijing Express In the blink of an eye, the "Qingming" of the traditional 24 solar terms has arrived. In the opinion of experts, as the warm and humid airflow moves northward in waves, when it encounters cold air from the south, it will cause frequent rainfall in the south. In the northern region, there will also be a large-scale rainfall process from west to east from the 18th to the 20th. Whether it is in the north or south, the temperature mostly shows a trend of high and then low.

Experts said that monitoring data showed that from 08:00 to 20:00 today (17th), there were short-term heavy rainfall, thunderstorms and strong winds in Fujian, Guangdong, Yunnan, Guizhou and other places. According to the analysis of the latest meteorological data, strong convective weather will still occur frequently in the south from the 18th to the 20th. For this reason, the Central Meteorological Observatory has also continued to issue a yellow warning for severe convective weather, among which, the strong convection from the evening of the 17th to the morning of the 18th may be mainly in Guizhou and Guangxi, and from the day to the evening of the 18th, it will be mainly in Guangdong and Hainan.
△National Severe Convective Weather Outlook (Central Meteorological Observatory/Fa)
It is worth noting that industry insiders emphatically pointed out that it is not difficult to find that the situation is also not difficult to find, as experts say, the strong convection potential area will expand northward on the 19th, and at that time, from Guangxi and Guangdong to Hunan, Hubei, Jiangxi, and Anhui. Judging from the current forecast, while the low-level warm and humid airflow strengthens to the north, in Guizhou, Hunan, Guangxi, and Guangdong, the upper altitude is at the bottom of the cold trough, and there is dry and cold advection; in such a situation, strong convection may be triggered; moreover, there is a certain vertical wind shear, and a "squall line" may appear. On the 20th, the cold air moved eastward and southward, and the strong convective potential area also showed an eastward and southward pressure trend.
