The persistent weather in Beibei.

This year, the whole world is affected by abnormal weather, which leads to the continuous rise of global temperature. Even China has not escaped such bad luck. Chongqing Beibei has set a new high temperature record. According to the statistics of the relevant meteorological bureau, the temperature in this area has risen to 45℃, which can be said to be the highest temperature since the local meteorological record was broken for two consecutive days. Even the local meteorological station continues to issue high-temperature red warning signal. It is no exaggeration to say that this is the eighth red high temperature warning issued by Chongqing since the summer of this year.

Why is Chongqing so hot?

Why Chongqing is so hot mainly depends on the geographical location, the influence of Qinghai-Tibet high and the urban heat island effect.

1, geographical location. Chongqing is located in the southeast edge of Sichuan Basin, among many parallel mountains with the same trend. This terrain is called the parallel ridge valley in eastern Sichuan. The main city of Chongqing is located in Wuyun Mountain, Jinyun Mountain, Zhongliang Mountain, Longwangdong Mountain, Tongluo Mountain, NanWenquan Mountain and Mingyue Mountain, separated from Huaying Mountain in Sichuan. In fact, from this geographical position, it can be analyzed that Chongqing is surrounded by mountains and belongs to a basin. In this state, the high temperature will continue to come down, thus entering the Chongqing area, which will naturally show a hot state.

2. Affected by the Qinghai-Tibet high. First of all, we should know that cardiogenic hypertension sometimes spreads to Chongqing during the swing. This tropical high pressure generated on land, driven by atmospheric circulation, will eventually enter the sky over Chongqing, and the cold and hot convection in the atmosphere will be blocked more seriously, which is not conducive to the generation of rainfall and strong winds, and will naturally lead to abnormal high temperature in Chongqing.

3. Urban heat island effect. Chongqing is not only a good place for tourism, but also a good place for industrial production, transportation and other daily work. These projects will aggravate the pollution of air pollution to urban air, and the good absorbents of infrared radiation such as air carbon dioxide will increase, so that the urban atmosphere will absorb more infrared radiation and heat up. This is also one of the important reasons for the high temperature in Chongqing.
