Hot weather means the temperature is above 35℃.

The standard of high temperature heat wave recommended by the World Meteorological Organization is that the daily maximum temperature is higher than 32℃ and lasts for more than 3 days. Meteorology in China generally refers to the high temperature when the maximum daily temperature reaches or exceeds 35℃.

Hot weather will make people feel uncomfortable, reduce work efficiency and increase the incidence of heatstroke, intestinal diseases and cardiovascular and cerebrovascular diseases. At the same time, high temperature weather will also have a greater impact on agricultural production.

Meteorology in China, 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".

Extended data:

Generally speaking, there are usually 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".

2. The standard of high temperature orange warning signal is that the maximum temperature rises above 37℃ within 24 hours.

3. The standard of high temperature red warning signal is that the maximum temperature rises above 40℃ within 24 hours.

In China, except for some areas such as the Qinghai-Tibet Plateau, high temperature weather occurred in almost all places, including Mohe in the northernmost part (five high temperature weather occurred in June of 20 10). The high temperature weather in China is mainly concentrated in May -65438+ 10.
