How is the ultra-high temperature weather formed?
High temperature means higher temperature. In different situations, the specific value is different, for example, in some technologies, it refers to thousands of degrees Celsius or even more; The highest daily temperature in meteorology in China is above 35℃, which is called high temperature weather.
High temperature weather will have a serious impact on human health, transportation, water and electricity consumption. High temperature warning signals are generally divided into three levels, namely yellow, orange and red.
The formation of high temperature is often inseparable from a specific weather system, one of which is the legendary subtropical high. In the area controlled by subtropical high, downdraft prevails. On the one hand, air sinking will compress and heat up, on the other hand, it is not conducive to the formation of clouds and rainfall, so high temperature weather with cloudy weather prevails in high pressure. In addition to natural factors, the formation of high temperature weather is also influenced by human activities. Under the climate background of global warming caused by the increase of greenhouse gases emitted by human beings, the frequency of extreme high temperature heat waves is also increasing.
