The temperature is 38 degrees. What is the surface temperature?
The ground temperature is the temperature at the junction of the atmosphere and the ground. The temperature of surface soil is called ground temperature, and the temperature of underground soil is called ground temperature. The ground temperature should be measured with a special ground thermometer. The measurement of surface temperature is to lay the thermometer flat on the ground, so that the surface body and the sensing ball are half buried in the soil and half exposed in the air; The underground temperature is measured by burying the thermometer in the soil to a certain depth, based on the depth of the middle part of the sphere from the ground.
In meteorology, the physical quantity representing the degree of air heat and cold is called temperature, which is referred to as temperature for short; The international standard unit for temperature measurement is Celsius (℃). The temperature mentioned in the weather forecast refers to the air temperature measured in the open air without direct sunlight (usually measured by blinds). The highest temperature is the highest temperature in a day, generally appearing in14-15; The lowest temperature is the lowest temperature in a day, which usually appears before sunrise.
