The temperature in Sichuan is over 40℃, ranking the top three in the national high temperature list. Why is the local weather so hot?

The summer heat in 2022 has arrived, and there have been widespread high temperature and heavy rain in various places, but Sichuan Province is located in the southwest of China and belongs to a typical subtropical monsoon climate. The topography is dominated by basin topography, which is relatively closed and difficult to dissipate heat at night. Therefore, the high temperature weather in Sichuan Province has existed for a long time, and the temperature exceeding 40 degrees swept the top three in China's high temperature list, which is also closely related to the topography.

According to the weather forecast of Sichuan province, the high temperature warning will be issued from July 5 to 9, 2022, so it can be seen from the weather forecast of Sichuan province that the high temperature weather will last for a long time, and the topography of Sichuan province is mainly valleys and basins, and the surrounding areas are mainly mountains, so it is difficult to dissipate heat. Therefore, topography is the main influencing factor of its high temperature, and high temperature and rainy weather in summer in subtropical monsoon climate zone is the influencing factor of its zonal high temperature.

In addition, according to the analysis of relevant personnel of China Weather Network, this high temperature weather was mainly affected by the eastward moving high pressure ridge, which led to sunny, hot and little rain climate in many northern areas. Thirdly, due to the short-wave radiation of the sun during the day, the weather is dry, which accelerates the rise of ground temperature. However, the obvious high ground temperature is mainly caused by the strong radiation of the sun. The sun is its main heat source, and the high temperature weather in Sichuan Province is remarkable in recent years, which is mainly caused by the radiation of the sun. In addition, Sichuan Province is located in China's inland areas, far from the ocean, and the small difference in thermal properties between land and sea is also an important factor.

In addition to these main factors, global warming is obviously aggravated, and air pollution is aggravated. In addition to rising sea level, melting glaciers and high temperature weather, it is also a manifestation of its influence. According to the current weather situation in Sichuan Province, the relevant departments in Sichuan Province have also issued high-temperature subsidies and early warnings to increase residents' awareness of high-temperature prevention. I believe that Sichuan province can better analyze and solve this high temperature weather.
