What's the high temperature up there?

When the temperature is above 35℃, it can be called "high temperature weather", and if the highest temperature exceeds 35℃ for several days, it can be called "high temperature heat wave" weather. Generally speaking, there are two kinds of high temperature, one is dry heat and high temperature with high temperature and low humidity. The other is hot and humid, which is called "sauna day".

The formation of high temperature is often directly caused by a specific weather system, and the most typical and common one is the subtropical high, which is known as the "high temperature messenger". In addition to natural factors, the formation of high temperature weather is also influenced by human activities.

Reasons for formation:

1, weather system trigger: the formation of high temperature is often directly caused by a specific weather system, and the most typical and common one is the subtropical high, which is known as the "high temperature messenger". In addition to subtropical high, continental warm high pressure, tropical cyclone, hot low pressure, weak cold front and other weather systems will also give birth to high-temperature heat waves.

2. Global warming provides the climate background: Under the influence of global warming, extreme high temperature events become more and more frequent.

3. Urban heat island effect "adding fuel to the fire": Urban heat island effect refers to the phenomenon that the temperature in the city center is higher than that in the suburbs. With the acceleration of urbanization, the urban heat island effect is more obvious, which undoubtedly contributes to the high temperature weather.
