Every time it is a hot day in midsummer,
a voice of doubt about the meteorological department will appear: It is already so hot, and the weather forecast really does not dare to say 40℃?
According to the content published by @hubeiweather Weibo:
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 temperatures in different environments are different.
In 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 publishes living weather indexes such as clothing index, ultraviolet index, etc., and Hubei Meteorology will also release somatosensory temperature forecasts, allowing everyone to feel the weather more intuitively. Hot.
4. Is the weather forecast really not going to say 40℃?
