Why does it always rain in Hunan?

Because Hunan is close to the 0-degree isotherm of China. It belongs to the subtropical zone and has a continental humid climate with a subtropical monsoon, which is obviously influenced by the East Asian monsoon. With the increase of the height of the sun in the northern hemisphere, the temperature rises, the cold air weakens, the warm and humid airflow from the ocean gradually strengthens, and the frontal rain belt formed by the intersection of cold and warm airflow gradually moves northward.

June is usually the main flood season in Hunan province, and June-August is the most concentrated period of rainfall in Hunan province, accounting for half of the whole year. In the past 25 years, the weather on June 7 -8 in Hunan Province was rainy 18 years.

Matters needing attention in rainy days

It is very dangerous to be near the river in rainy days, because the river is extremely unstable at this time, and it may be fine, and it may rise in an instant, but the power cannot be underestimated. So remember, for the sake of safety, it is better to stay away from the river in rainy days, and it is best not to go there until after the rainy season.
