The weather in northwest China in August.

In China, the rainy season is from April to September in the south and from June to September in the north. The front rain in July and August is located in North China and Northeast China.

The rainy season refers to the wet and rainy season with relatively concentrated precipitation every year. China is a country with obvious monsoon climate, and the seasonal distribution of precipitation varies greatly. Heavy rain and torrential rain often occur in this season, and its precipitation accounts for about 70% of the total amount of the year. Generally, the rainy season is from April to September in the south and from June to September in the north. The difference between before and after is 2 or 3 months. The rainy season ends early in the north and late in the south, with a general difference of only about 20 days.

According to the different seasons, the front rain has been raining. From winter to summer, the position of the frontal rain and precipitation belt gradually moved northward, and in July and August, the frontal rain belt moved to North China and Northeast China (there was a summer drought in the middle and lower reaches of the Yangtze River).

Extended data

The characteristics of frontal rain are as follows:

1, with a large horizontal range, often forms a large-scale banded precipitation area along the front, which is called precipitation zone. With the seasonal movement of the average position of the front, the position of the precipitation belt also moves.

2. The long duration is due to the low rising speed of stratiform clouds, low water content and low precipitation intensity. Some pure water clouds rarely have precipitation, and when there is precipitation, it is also Mao Mao rain. However, the frontal precipitation lasts for a long time, ranging from a few days to 10 day and a half, sometimes exceeding 1 month. "Rain after rain in Qingming Festival" is an accurate and appropriate description of frontal precipitation in Jiangnan area of China.
