What is the impact of the pressure zone in southern Fujian now? Why is it raining continuously?

Controlled by subtropical high in late spring and early summer, the weather is fine.

At present, winter is mainly influenced by the winter wind, that is, the northwest wind, which blows from the inland to the southeast coast, bringing the cold air from Siberia to the south of Fujian, where it meets the local warm air mass to form a front rain (cold front).

In winter, the cold air keeps going south, the latitude in southern Fujian is low, and the intensity of warm air is not weak, resulting in a stalemate and continuous rainy weather. If cold air or warm air is controlled by a single air mass, it will be sunny.
