What is the difference between air temperature and temperature?
The temperature of gases in the atmosphere is the air temperature. Temperature is a physical quantity that expresses the hotness and coldness of an object. Microscopically speaking, it is the intensity of thermal motion of the molecules of an object.
Temperature is a meteorological term, generally referring to the temperature of the atmosphere. The temperature in the weather forecast refers to the air temperature measured in the open air without direct sunlight. The international standard unit of temperature measurement is degrees Celsius (℃). The maximum temperature is the highest value of the temperature in a day, which generally occurs at 14-15 o'clock, and the minimum temperature generally occurs at 5-6 o'clock in the morning. China uses the Celsius temperature scale, expressing degrees Celsius in °C. Generally, observations are made 4 times a day (02, 08, 14, and 20 times). Some stations observe 3 times a day (08, 14, and 20 times) based on actual conditions. Temperature is an important indicator used to measure the distribution and changing trend of atmospheric temperature on the earth's surface. It can be divided into daily average temperature, monthly average temperature and annual average temperature according to needs. It is also an important reference for guiding people's normal life and production activities.

Temperature (temperature) is a physical quantity that expresses the degree of hotness and coldness of an object. Microscopically speaking, it is the intensity of thermal motion of the molecules of an object. A degree of hot or cold measured on one of several arbitrary scales based on an observable phenomenon (such as the expansion of a column of mercury). Temperature can only be measured indirectly through certain characteristics of an object that change with temperature, and the scale used to measure the temperature value of an object is called a temperature scale. It specifies the starting point for temperature readings (zero point) and the basic unit for measuring temperature. The SI unit is the thermodynamic temperature scale (K). Currently, other temperature scales that are commonly used internationally include the Fahrenheit scale (°F), the Celsius scale (°C) and the International Practical Temperature Scale. From the perspective of molecular kinetic theory, temperature is a symbol of the average kinetic energy of molecular motion of an object. Temperature is the collective expression of the thermal motion of a large number of molecules and has statistical significance.
