"It's already so hot, why doesn't the weather forecast say 40°C?"
Is it true that the weather forecast doesn't say 40°C? Of course not. On July 24, the Wuhan Central Meteorological Observatory issued a high temperature red warning, clearly mentioning that some areas will exceed 40°C.
Since this week, the high temperature weather in Hubei has continued to develop, with extreme temperatures above 40℃ occurring in many places. During the day on July 24, the temperature at two national stations, Wufeng and Tongcheng, exceeded 40°C, and nearly one-fifth of the regional weather stations had the highest temperature exceeding 40°C.
The measured temperature at many regional stations in Wuhan reached over 41°C, with the highest temperature at Caidian Xinmiao Observation Station reaching 42.4°C.

Some netizens are wondering why the outdoor temperature displayed in the high-speed rail carriage is higher than the temperature forecast by the meteorological department?
There is a standard environment for temperature measurement.
There is a difference between air temperature and body temperature.
1. There is a standard environment for temperature measurement. According to the World Meteorological Organization, the temperature monitored by the meteorological department is the temperature measured by the thermometer in the shutter. The blinds must be placed on the lawn, 1.5 meters above the ground, with a relatively open surrounding, and no tall buildings, trees, etc. blocking the wind or sunlight.
2. The temperature of different environments is different. Within the same city, there are certain differences in temperature in different places due to various influences such as the underlying surface, surrounding buildings, and vehicles. In summer when the sun shines strongly, the temperature of cement roads and asphalt roads often exceeds 50℃, and dark seats after exposure can even reach above 60℃. Therefore, the water temperature, ground temperature, car temperature, etc. that we measure are not equal to the air temperature. !
3. There is a difference between air temperature and body temperature. At present, the meteorological department comprehensively considers the impact of air humidity, wind, radiation, etc. on the human body, and releases living weather indexes such as clothing index and ultraviolet index, as well as body temperature forecasts, so that everyone can feel the hot weather more intuitively.
Therefore, the temperature in the weather forecast is not the body temperature. However, the hot weather will soon ease. The outer cloud system of Typhoon No. 3 "Gemei" will bring rainfall and strong winds to Hubei.
Weather Trend
Typhoon "Gemei" has strengthened to a super typhoon level on the morning of July 24. It made landfall in Taiwan on the night of July 24, and then passed through Taiwan Island. It will be in Taiwan from the afternoon to night of today (July 25). It made landfall along the coast of Fujian, and then continued to move northwest. The moving path is most likely to be Fujian-Jiangxi-Hubei-Henan, and its intensity gradually weakened.
Affected by Typhoon "Gemei", it is expected that there will be heavy rain in the east and north of Hubei Province from the night of July 25 to July 28. Heavy rain will occur in some areas of Xianning, Huangshi, Huanggang, Ezhou, Wuhan, Xiangyang, Shiyan and other places, with single points Heavy rainstorm. The hot weather will ease, with the maximum temperature dropping to 30°C to 34°C in most areas. In addition, winds will increase in the central and eastern regions from July 26 to July 27, with gusts reaching levels 7 to 9.
