Sichuan surface temperature

The summer heat in 2022 has arrived, and there are high temperature and heavy rain everywhere. However, Sichuan Province is located in the southwest of China and has 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 above 40 degrees occupies the top three in China's high temperature list, which is also closely related to the terrain.

According to the weather forecast of Sichuan Province, a high temperature warning was issued from July 5 to 9, 2022. From the weather forecast of Sichuan Province, we can see that the high temperature weather in Sichuan Province will last for a long time, but most of the terrain in Sichuan Province is dominated by valleys and basins, and the surrounding areas are dominated by mountains, which makes it difficult to dissipate heat. Therefore, topography is the main influencing factor of its high temperature, and high temperature and rainy weather in subtropical monsoon climate zone in summer is the influencing factor of its zonal high temperature.

In addition, according to the analysis of the relevant personnel of China Weather Network, this high temperature weather is mainly affected by the eastward movement of the ridge of high pressure, resulting in sunny and hot weather in many places in the north. Thirdly, due to the short-wave radiation of the sun during the day, the weather is relatively dry, which accelerates the rise of the surface temperature. The obvious high surface temperature is mainly caused by the strong radiation of the sun. The sun is its main heat source. In recent years, the high temperature weather in Sichuan Province is remarkable, which is mainly caused by solar radiation. 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 also reflects its influence. According to the current weather situation in Sichuan Province, the relevant departments in Sichuan Province have also issued high-temperature subsidies and made early warning work to increase residents' awareness of high-temperature prevention. I believe that Sichuan province can better analyze and solve this high temperature weather.
