Will Chongqing temperatures reach 50 ° C?Fake, don't believe it!

On the 13th, the Chongqing Municipal Government News Office held a press conference on the safety prevention work of the city in 2022. Zhou Guobing, the director of the Municipal Meteorological Observatory, rumored that the temperature of Chongqing will reach 50 ° C on the Internet recently, and popularized the relevant knowledge of temperature.

Rumor!

The temperature of Chongqing will reach 50 ° C, fake!

Zhou Guobing said that Chongqing's temperature will reach 50 ° C recently on the Internet. This is tampered with by netizens. It is fake. Please do not believe in rumors and rumors. And simply science four points about temperature:

① The temperature gradually decreases as the altitude increases. Generally speaking, the temperature of the temperature decreases by 0.6 ° C every 100 meters above sea level.

② In the meteorological business, the temperature refers to the temperature measured in the shutters at a height of 1.5 meters from the ground. According to the meteorological observation specifications, the measurement temperature must be completed in a relatively empty place. The temperature table is 1.5 meters above the ground, and it is placed in the louvery box. The shutters are required to be ventilated. To avoid the direct irradiation of the sun, and to avoid being reflected by the ground The influence of light and heat, so the measured temperature is the temperature in meteorology, and is representative, accuracy, and comparative.

③ The temperature temperature refers to the air temperature that the human body feels in different environments. Under the same temperature conditions, people will have different warmth feelings due to different cold and warm feelings due to different humidity, wind speed, solar radiation, dressing color and even mood.

For example, at the same temperature, the greater the humidity, the more hot it feels; if there is wind, you can take away the heat of the human body, and everyone will feel the effect of cooling; if it is irradiated with the sun, the human skin temperature will increase. Therefore, the temperature and meteorological temperature of the human body are still different.

④ The surface temperature refers to the temperature at the junction of the ground and the air. When measuring the surface temperature on the meteorology, the ground temperature surface is placed horizontally on the ground surface. Half of the balls are buried in the soil and the other half is exposed to the air. Therefore, the measured temperature cannot completely represent the surface temperature, but the surface temperature With the average of the air temperature close to the surface.

This value is different from the surface temperature of the cement floor and highway floor that you often mention. We can also feel that the surface temperature measured on the cement floor is obviously far higher than the temperature or the surface temperature in the air we call the air.
