Why is it so hot in Sichuan this summer?
1, high and low pressure collision compression
From the meteorological point of view, the temperature rise in any area is actually a temperature change, and the temperature change is due to the role of air pressure. The high air pressure over Sichuan mainland caused some air currents to drop and others to rise. The two collide to form compression, which eventually makes the air temperature higher and higher.
2. No rain for a long time makes the soil and air temperature very high.
In daily life, we will find that if it rains for several days, not only the temperature is low, but also the temperature of objects such as soil is falling. Due to the high temperature and little rain in Sichuan this year, the air and soil temperatures are very high. Under the action of high and low air pressure, the temperature of air and soil can't drop, but it helps to raise the temperature.
3. The warm high and subtropical high in the western plateau are integrated.
China is low in the east and high in the west. Every year, a warm high is formed from Central Asia, and after entering China, it becomes an unusually strong warm high together with the continental high. At the same time, a southwest subtropical high will enter Sichuan, and the two high pressures will eventually merge into one, resulting in the continuous high temperature weather in Sichuan this year.
