Why doesn't it snow in Guangdong

Because of its geographical location, it seldom snows in Guangdong.

Guangdong province belongs to the East Asian monsoon region, which is characterized by subtropical climate, subtropical climate and tropical climate from north to south. The whole territory is located at 2013' ~ 25 31'north latitude and109 39' ~1719' east longitude. From north to south, the annual average sunshine hours increased from less than 1500 hours to more than 2,300 hours, and the annual average temperature was about 19℃-24℃.

The formation of snow requires two conditions, one is cold ice crystal nucleus, and the other is water. When the temperature in the cloud drops below freezing point, water will form ice crystals, which are called cold ice crystal nuclei. When these ice crystal nuclei accumulate to a certain extent, they will fall, which is what we see as snowfall.

The climate in Guangdong, especially in Guangzhou and the Pearl River Delta, is quite different from that in the north. The winter climate in southern China is mild, with little rain and snow. The average temperature is about 2℃ to 4℃ higher than that in the middle and lower reaches of the Yangtze River. Snowfall mostly occurs in 1 and February.

According to the atmospheric circulation situation, since the beginning of the light snow solar term, low pressure or trough has often appeared in high latitudes, which will bring a large range of cold air when moving eastward and southward, and there will be a large range of windy and cool weather in China. If the cold air is strong and the warm and humid airflow is active, it may snow.

Snowfall is a form of precipitation at low temperature, water vapor is the foundation, and temperature is very important. For snow, there is no shortage of low temperature in the north, just watching water vapor, and there is no shortage of water vapor in the south, just waiting for low temperature.
