Is there a sauna in Inner Mongolia?The city with the most sauna days is ...

Sauna days refer to high temperature, high humidity, and small wind speed, giving people like steaming safflowers. According to the "Sauna Weather Grade" based on the Meteorological Industry Standard of the People's Republic of China on September 1, 2021, in the Inner Mongolia Autonomous Region, the standard for sauna weather is to meet at the same time: the highest temperature of the daily maximum temperature ≥32 ° C, the average daily relative humidity ≥60%, and the daily daily. The maximum wind power ≤ 3 (that is, the daily maximum wind speed ≤5.4m/s), and it is only a "sauna sky". The reason why "sauna" is so uncomfortable is because the calories in the human body cannot be emitted in time. When it is hot, the human body can cool down through sweat and evaporate sweat, which can take away the heat of the body. When the surrounding environment is high, the evaporation speed of sweat will greatly reduce, and the small wind speed will cause the air flow speed to become smaller, making the surrounding high humidity environment around the skin, which is more not conducive to the evaporation of sweat.

This summer, most parts of my country have gone through the strongest high temperature process since 1961, which has the characteristics of long duration, wide range, strong strength, and strong extremes. Compared with previous years, this year's high temperature process endurance is particularly durable.

So, what is the situation of sauna in the Inner Mongolia Autonomous Region that has performed compared with previous years?

The meteorological department conducted statistical analysis of the data of the national ground meteorological observation stations since 2000 years since the area of ​​the twelve alliance (cities) governments in the region. As shown in the figure below::

A total of 309 sauna weather has appeared in the autonomous region since 2000. According to regional statistics, Tongliao has reached the list with 134 sauna weather, while Ordos and Alashan League have never appeared in sauna since 2000.

In terms of annual statistics, the number of sauna weather in 2022 is the largest in 2000, which is related to the strongest high temperature weather process in my country, but the strength is relatively weak, and it is also related to the relatively dry climate in the autonomous region.

Inner Mongolia Tongliao is the top of the sauna weather, but the Alashan League, which often releases high -temperature orange and red warning, has never appeared in sauna. Is this the wrong meteorological bureau? In fact, this is because of the "sauna sky". Equal to high temperature.

When the temperature reaches 35 ° C, it can be determined by the temperature. In contrast, the judgment of the "sauna" requires comprehensive consideration of temperature, relative humidity and wind speed. Taking Tongliao as an example, the number of high temperature days has been 104 days since 2000, but the number of "sauna days" has reached 134 days, 30 days more than the high temperature day. In Wuhai City, which appeared only 12 times, there were 390 times in high temperature weather.
