Has Hangzhou returned to Nantian? When will Hangzhou return to Nantian?

1, Hangzhou, Hangzhou and Wuzhen returned to Nantian in March. Zhejiang returns to Nantian from March to April. Returning to the south sky is a weather phenomenon in southern China, which usually refers to the phenomenon that the temperature begins to warm up and the humidity rises sharply every spring. From March to April every year, warm and humid air from the South China Sea meets cold air from Siberia, forming a quasi-static front in the south, which makes the weather in the south changeable and very humid, with light rain or fog during the period, resulting in the phenomenon of returning to the south.

2. From the meteorological point of view, after a long period of low temperature, the surface of the object is completely cold. When the temperature of the object is less than or equal to the dew point temperature, the water vapor in the air reaches saturation and begins to condense on the surface of the object, causing water droplets and returning to the south.
