What's the difference between temperature and temperature?

The temperature of gas in the atmosphere is the air temperature, which is a physical quantity indicating the degree of heat and cold of an object, and is the intensity of molecular thermal movement of the object at the microscopic level.

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 outdoors without direct sunlight. The international standard unit for temperature measurement is Celsius (℃). The highest temperature is the highest temperature in a day, which generally appears at 14- 15, and the lowest temperature generally appears at 5-6 am. China uses centigrade scale, which is expressed in degrees Celsius. Generally, observation is made four times a day (02, 08, 14, 20), and some stations observe three times a day (08, 14, 20) according to the actual situation. Temperature is an important index to measure the distribution and changing trend of atmospheric temperature on the earth's surface. According to needs, it can be divided into daily average temperature, monthly average temperature and annual average temperature. It is also an important reference to guide people's normal life and production activities.

Air temperature

Temperature is a physical quantity that indicates the degree of heat and cold of an object, and it is the intensity of molecular thermal motion of the object at the microscopic level. According to an observable phenomenon (such as the expansion of mercury column), the degree of heat and cold is measured by one of several arbitrary scales. Temperature can only be measured indirectly through some characteristics of an object that changes with temperature. The scale used to measure the temperature value of an object is called a temperature scale. It specifies the reading starting point (zero point) of temperature and the basic unit for measuring temperature. The international unit is the thermodynamic temperature scale (K). At present, other temperature scales widely used in the world are Fahrenheit scale (F), centigrade scale scale (C) and international practical temperature scale. From the point of view of molecular motion theory, temperature is a sign of the average kinetic energy of an object's molecular motion. Temperature is the collective expression of a large number of molecular thermal movements, which has statistical significance.
