What weather often occurs in South China?

Return to Nantian.

"Hui Nantian" is the name for the phenomenon of weather return in Hainan, Guangxi, Guangdong and other places in South China. It usually occurs in February and March in spring, when the temperature warms up and the air humidity rises sharply.

On a clear night, because there are no clouds, the ground heat dissipates quickly. In the first half of the night, because the ground stores more heat during the day, the temperature generally does not drop below 0°C. Especially in the second half of the night and before dawn, a lot of heat is emitted from the ground, but very little heat is compensated by atmospheric radiation. The temperature drops quickly. When the temperature drops below 0°C, the water vapor in the air near the ground adheres to the ground. Hoarfrost condenses into ice crystals on objects such as soil, stones, leaves, vegetation, and low-rise tiles.
