2011Did it hail in Xiangfan, Hubei Province on the night of July 30th?

2011At 2: 30 pm on July 25th, heavy rain and hail began to fall in Group 4 of Wandu Village, Taipingdian Town, fancheng district.

At 3: 00 pm on July 25th, Xiangfan Meteorological Observatory issued three warning signals: thunder, strong wind and heavy rain. Affected by strong convection, there will be thunderstorm, strong wind and hail weather in the next three hours, with local precipitation of 20-50 mm and strong wind of 7-9.

At 4 o'clock in the afternoon, it was stormy, lightning and thunder, and dark clouds hung over the city. According to the statistics of the municipal meteorological department, as of 6 pm, the urban rainfall was 48.5 mm, and the maximum rainfall was 97 mm in the ancient city of Cihe. Rain brings coolness, but it also brings disaster. The temperature dropped by 65438 02℃ within 3 hours. At 2 pm, the temperature was still 35℃, and at 5 pm, the temperature dropped to 23℃.

Yang Furong, deputy director of the Municipal Meteorological Observatory, said that the convective weather was severe, and the hail and bad weather were caused by the convergence of cold and warm air at the edge. According to radar monitoring, hailstones appeared in Xiangzhou District, northern Baokang and southern Gucheng, and soft hailstones and small hailstones also appeared in northern Nanzhang.

It's still muggy in the morning. Why did it suddenly rain and hail in the afternoon? Yang Furong explained that during this period, the warm and humid air flow in the southwest was particularly active, the sun was shining high, and the temperature rose very quickly. However, this has caused the situation of high ground temperature and low air temperature. The collision of cold and warm air currents is easy to form strong convective weather, especially thunderstorm weather in the afternoon. At the same time, it also created conditions for the formation of hail.
