What is the change of air humidity in South China in four seasons?

The changes of air humidity in South China in four seasons are as follows:

1. Spring: In the south, spring is usually one of the wettest seasons of the year. This is because after winter, the cold air is no longer as strong as in winter, so the warm and humid air from the ocean begins to strengthen. At the same time, there is relatively more rainfall in spring, which further increases the humidity of the air.

2. Summer: Although the temperature in summer is usually not as high as that in the north, it is still relatively high in the south, so the humidity is relatively high. However, compared with spring, the humidity in summer may be slightly lower.

3. Autumn: As winter approaches, the air in the south begins to get dry. This is because the warm and humid air from the ocean began to weaken and the rainfall began to decrease. Therefore, the humidity in autumn began to drop.

4. Winter: In the south, the humidity in winter is usually lower than that in spring and summer, but there is still some humidity. Although it rains occasionally, on the whole, it rains less in winter.

Generally speaking, the air humidity in the south is high in spring and summer and relatively low in autumn and winter. However, the specific humidity change will be affected by many other factors, such as weather system and geographical location.
