The temperature gauge in the shutter box of the weather station exceeds the degree above which it is a high temperature day

It is a high temperature day when the thermometer in the shutter box of the weather station exceeds 35℃. Meteorological observation instruments are placed inside the louvers, which can circulate through the air. There are various instruments such as thermometers, hygrometers, maximum and minimum temperature meters, etc. inside the box. These instruments are used to measure the temperature and humidity of the air, so it is hoped that the temperature and humidity inside the box will not change due to the heating of the box walls by sunlight.

Main types of high temperature:

1. Dry heat type

High temperature weather with extremely high temperature, strong solar radiation and low air humidity is called dry heat type high temperature. In summer, it often appears in northern areas such as Xinjiang, Gansu, Ningxia, Inner Mongolia, Beijing, Tianjin, Shijiazhuang, Liaocheng, Shandong and other places.

Because people feel like taking a sauna in a sauna when this kind of weather occurs, it is also called "sauna day".
