When will Fuzhou return to Nantian?

Returning to Nantian often occurs in the season of alternating February and March, and generally ends in April.

Returning to Nantian is a weather resurgence phenomenon, which mainly occurs in South China. It seems that the floor, ceiling, glass and walls can squeeze out water at any time, and I feel that mushrooms can grow on my head at any time. The feeling of being wet is quite uncomfortable. Everything at home is wet.

The principle of returning to Nantian is that at this time of year, the warm and humid air flow from the sea begins to increase. After the cold air leaves, the warm and humid airflow quickly counterattacks, resulting in an increase in temperature and air humidity. At this time, after a winter's low temperature in the south, the surface of the object is completely cold. When some cold objects meet with warm and humid airflow, they are easy to produce water droplets, and the walls and even the ground will "water". So generally speaking, the formation of returning to Nantian requires two conditions: first, there must be a long-term low temperature; Second, the weather changes suddenly. After a long period of low temperature, the weather suddenly gets warmer, the humidity increases, and there is more water in the air.
