When does it snow in Guangdong?
Snow in Guangzhou is an extremely rare weather, which has only been recorded once since this century, that is, the cold wave of 20 16 and 1. Of course, there were also witnesses in March 2005, but there was no official observation record. It can be seen that whenever it snows in Guangzhou, the possibility is extremely low. But secondly, in mid-June, 5438+February, there were indeed signs of a big cold wave. The engine of this big cold wave is the cold vortex in western Siberia. From 12 and 10, it gradually approached Xinjiang, bringing cold weather to Xinjiang.
65438+February 65438+May, after soaking in Xinjiang, the cold vortex will slowly move eastward, which may drive the Siberian cold air south to China. In this cold wave, the temperature in South China, Fujian, Taiwan Province and Yunnan will drop, without exception. For Cantonese people, it is not snow that should be guarded against, but the extreme heat of nearly 30 degrees before 65438+February, 15 years ago, and the drastic changes in cold and warm after 65438+February, 16 years. In 65438+February, such a big temperature change is rare in Lingnan.
