What does the temperature in the atmosphere mean?
Temperature refers to the temperature of air, that is, the physical quantity of air's hot and cold degree is called temperature. The difference of temperature is one of the main factors that cause the difference between natural landscape and our living environment, which is closely related to our life. The temperature is directly determined by solar radiation and solar height, and is also affected by conditions such as airflow, cloud cover and topography.
Generally speaking, the temperature we are concerned about is mainly based on the weather forecast, and the temperature mentioned in the weather forecast refers to the air temperature measured in the open air without direct sunlight, usually measured in a louver. The highest temperature is the highest temperature in a day, which generally appears in 14- 15. The lowest temperature is the lowest temperature in a day, usually before sunrise.
Atmospheric temperature, referred to as air temperature for short, refers to the temperature at the height specified by ground meteorological observation (i.e. 1.25 ~ 2.00 meters, and 1.5 meters in China). The international standard unit of temperature measurement is Celsius (℃), and some are expressed in Fahrenheit (F), all of which take one decimal place, and negative values mean MINUS.
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. 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.
The temperature scale 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 and centigrade scale scale.
