20 16 65438 Shenzhen1October 24th, the ice particles were recorded for the first time. It didn't snow in Shenzhen because the echo intensity of cold weather was not enough.
Because the precipitation clouds are mainly concentrated in the south-central part of Guangdong Province (except Leizhou Peninsula), Shenzhen is located in the center of the precipitation clouds. Under the double attack of cold air and precipitation clouds, light rain mixed with ice particles occurred in Shenzhen during the day on the 24th, and the temperature will be as low as 65438 0℃ on the 25th, which is rare in history, with strong rainfall and wind.
Extended data "freezing" phenomenon
On the evening of 23 October, 2065438+16/kloc-0, the Shenzhen Meteorological Observatory announced that due to the low temperature and strong wind, and the recent rain and fog on the top of Wu Tong, the thatch, branches and even automatic weather stations on the top of the mountain were "frozen" with a layer of ice shells, but this was not snow, but a "frozen" phenomenon.
Because the temperature at the top of Wu Tong Mountain is below 0℃, and it has been in fog recently, the air humidity is very high, so fog drops or raindrops in the air will form ice shells when they meet plants or trees below 0℃, telephone poles, the ground and other objects. This kind of phenomenon is rare in Shenzhen, and it only appears on high mountains like Wu Tong.
Freezing requires three conditions:
1, and the condensation condition that the temperature is maintained near or below 0℃ is required.
2. This is a continuous freezing rain, Mao Mao rain or dense fog-water vapor condition.
3. Appropriate wind speed to enhance condensation
