△Satellite monitoring of the national weather (Fengyun-4 satellite/development)
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 the monitoring data shows that today (17th) we can see the temperature rise and fall dominated by the light radiation factor; among them, the eastern part of the northwest, north China, and northeast China are sunny and warm; however, the south of the Yangtze River has cooled down because of the rain. After the warming, many places in the north and the south of the Yangtze River formed a "north-south upside-down". For example, Jiamusi in the north of Heilongjiang rushed to 20°C, which is much higher than Shanghai and Hangzhou in the south of the Yangtze River.

It is worth noting that industry insiders stressed that it is not difficult to find that it is not difficult to find that from 08 o'clock to 14 o'clock today, the southern part of Anhui is near the low vortex shear line, and the precipitation intensity is relatively large, and it occupies 13 of the top 20 places in the precipitation list. In addition, strong convection occurred in parts of Fujian and Guangdong. For example, in Heyuan, Guangdong, there was a level 8 thunderstorm and strong wind from 13 o'clock to 14 o'clock. In the eastern part of the source of the river, there is a strong purple echo, and hail may occur locally. In addition, convection is also developing in the upper reaches of the west side of Fuzhou, which may affect the urban area of Fuzhou in the future. (Editor-in-charge/Xiangyu)
