How long will the drought in Chongqing last?

The weather in September is expected to be sunny, hot and rainy.

Yesterday, the person in charge of the Meteorological Information Center of the National Meteorological Administration predicted that the temperature in Chongqing was still high in September. In the next 10 day, the weather in Chongqing will still be mainly sunny and hot, and it will be in a high temperature period on September 3. After September 4, the temperature will drop, and the hot weather will ease, but the rainfall will be less.

The reason notified by Chongqing Meteorological Bureau is that atmospheric stagnation-that is, the comprehensive performance of various air currents in the earth's atmosphere is abnormal, which leads to the continuous high temperature and hot weather in Chongqing, mainly in the following aspects:

1. Since the summer, the intensity of the western Pacific subtropical high is unusually strong, and the ridge line is located in the northwest. Influenced by the high-pressure system, downward flow prevails in Chongqing, with little precipitation, which is prone to persistent drought.

2. The cold air activity in Chongqing is weaker than normal, which makes the precipitation weather process in Chongqing obviously less and weaker.

3. The Qinghai-Tibet high is stronger than normal, and it is connected with the subtropical high to form a strong high pressure area, which continuously controls most parts of Chongqing.

4. A large number of typhoons landed this year, which were blocked by the mainland high pressure, making the subtropical high and high pressure zone close to the sky, and it rained around the subtropical high and high pressure zone, making it difficult for Chongqing to rain.

5. The water-gas channel is blocked by the continental high pressure, which leads to insufficient water-gas conditions, low temperature, drought and little rain in Chongqing.

The abnormal operation of these air currents makes Chongqing's climate present a "northwest arid zone state".

It will not change until mid-September.
