People's Voice of the World, May 13, Beijing Express In the blink of an eye, the traditional 24 solar terms of "Lixia" have arrived. On the national weather stage this week (May 13-May 19), in the opinion of experts, the maximum temperature in many places in the north will hit new highs one after another and reach or exceed 30°C. The rain in the south will mainly surround Yunnan and Hainan during the week.

Experts said that according to the analysis of the latest meteorological data, from the 14th to the 15th, there were moderate to heavy rains and localized heavy rains in southwestern Guizhou, eastern and southern Yunnan, western Guangxi, Hainan Island and other places. From the 18th to the 20th, there will be a moderate to heavy rain process in Jianghan, Jianghuai, Jiangnan, South China, Sichuan Basin, Guizhou, Yunnan and other places, with heavy rain in some areas, and heavy rain in southern Jiangnan and northern South China. In addition, the precipitation from the 18th to the 20th will also affect the north; At that time, there will be light to moderate rain and local heavy rain in the eastern part of Northwest China, North China, Northeast China, Huanghuai and other places.

According to experts, judging from the current forecast, the precipitation process from the 18th to the 20th, the water vapor and energy conditions are better; Therefore, the central and eastern regions should be vigilant against the possibility of short-term heavy rainfall, thunderstorms and strong winds and other strong convective weather. According to the official forecast of the Central Meteorological Observatory and the numerical model forecast of European and American meteorological institutions, it can be seen that the situation of the two rounds of rainfall is not the same. Among them, the northeast wind of low-level cold air from the 14th to the 15th moved southward, which in turn triggered convection. However, because the warm and humid airflow is not strong, the intensity of rainfall over the general area is not large; However, in Yunnan, Hainan and other places, the convection at a single point may be strong, which should not be underestimated.

It is worth noting that industry insiders emphasized that it is not difficult to find that the situation is also not difficult to find, as experts said, the precipitation process from the 18th to the 20th corresponds to the southerly warm and humid airflow at low altitude to enhance the north, and the water vapor transport all the way to North China and Northeast China. Moreover, judging from the current development, the South China Sea summer monsoon may break out in late mid to early late mid to late late; Thus, the monsoon swells northward, driving the rainfall; So, it's more ferocious than the usual warm and cold rainfall. Therefore, from the 18th to the 20th, the rainfall will be more extensive and will be stronger. (Editor-in-charge/Xiangyu)
