Early warning of the latest weather news in Sichuan

Different degrees of high temperature have appeared everywhere this summer. According to the latest weather forecast in Sichuan Province, it is predicted that after experiencing high temperature, there will be thunderstorms in the future, and some areas will even face heavy rain, and the precipitation will reach more than 100 ml. So many friends are also very confused about this. Why does it bring precipitation after high temperature? What is the reason? Today, Bian Xiao will talk to you about this topic in detail.

When the temperature rises, there will be a corresponding rainstorm. The main reason is that the current temperature rise is the function of high temperature and air pressure. Then in this case, after the temperature rises for a long time, the surface temperature in this area will be too high, leading to excessive surface evaporation. At this time, clouds rich in water vapor will form in the sky. Then, after accumulating to certain conditions, strong air convection will be formed to form rainfall, which is why heavy rains and thunderstorms are often seen after high temperature weather, mainly due to the friction of clouds.

The heavy rainfall in Sichuan province is caused by two high-pressure air currents. When the temperature rises under the action of high-pressure airflow, water will be constantly transpiration due to high temperature, and the original basin landform in Sichuan will increase the humidity of the air. Under the influence of such airflow, the weather will become more and more extreme, and some areas may have violent storms, which is also the reason why high temperature will be accompanied by heavy rainfall.

To sum up, there will be sudden cooling after high temperature in some areas. The main reason is that water vapor is taken away by high temperature, and clouds rich in water molecules condense in the air. Under the influence of this situation, some areas may have frequent rainfall. Of course, according to the weather forecast, the current rainfall and high temperature are within the normal range, which is not a special case.
