Why is it always cloudy in the south?

There are many reasons for the rainy days in the south.

First, according to the explanation of China Meteorological Bureau, continuous rainy weather like this is called continuous rainy weather, which has the characteristics of low temperature, few sunshine hours, low rainfall intensity, long rainfall duration and wide distribution of rain areas. The main reason for the continuous rainfall is that the warm and humid air in the south is relatively active, while the cold air in the north has a certain intensity and frequent activities. When the cold air from the south reaches Jiangnan and South China, especially when the main cold air from the east of China meets the warm and humid air from the tropical ocean, it often forms low temperature and continuous rain at the intersection of the two. The same is true of the heavy rain this year.

Second, the continuous rainy weather has brought a lot of trouble for everyone to travel. Not only that, the continuous rainy weather also does a lot of harm to farming, delaying spring sowing and ripening. Early rice seedlings lack heat and light, resulting in the death of rotten seedlings, forming wet waterlogging damage and affecting the growth of summer sowing crops. Moreover, low temperature and high humidity can easily cause diseases and pests of wheat and rape. Therefore, it is estimated that the crop harvest will be affected this year.

Third, but in the long run, abundant precipitation, especially precious spring rain, can effectively improve soil moisture and is beneficial to agricultural production.

From the weather forecast, it can be seen that in recent days, the rainy weather in the south will gradually decrease, the sunny and warm days will gradually increase, and the sunny days are not far away.
