What weather system affects the spring drought in North China?

The main reasons for the spring drought in North China are as follows:

1. According to the movement law of rain belt, the spring rain belt is still in South China and gradually moves northward, while North China has not yet entered the rainy season.

2. North China is a typical monsoon climate, with rapid warming and large evaporation in spring.

Spring in North China is spring ploughing, and there is a great demand for water. Other factors: North China has a large population, developed industry and agriculture, large water consumption and serious pollution.

The precipitation in North China mainly depends on the water vapor brought by the east monsoon from the Pacific Ocean, but the east monsoon mainly affects South China in spring, and the east monsoon has not affected North China yet, so the precipitation in North China is less and the evaporation is greater than the precipitation.

Industrial development in North China, especially heavy industry, needs a lot of water for industrial development, and so does natural water consumption. There is a large population in North China, and there is more domestic and agricultural water, so there is even less water resources in North China, which is the reason for the spring drought in North China.
