The temperature observed and recorded by the weather station is measured by a thermometer placed in the shutter. The height of the thermometer is 1.5m above the ground. Centigrade scale is generally used to measure temperature, which is recorded as "℃" and pronounced as "Celsius".

Generally, the temperature is observed four times a day: 8: 00, 14: 00, 20: 00 and 2: 00 Beijing time. According to local conditions and needs, the number and time of observation may not be exactly the same.

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, usually before sunrise.

The temperature mentioned in the weather forecast was measured on the thermometer in the louver box 1.5 meters above the ground of the observation site. Because the thermometer keeps good ventilation and avoids direct sunlight, it is representative.

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.

Temperature records can characterize the thermal characteristics of a place, which is indispensable in both theoretical research and the application of national defense and economic construction. Temperature is one of the conventional measurement elements in ground meteorological observation.

The temperature has a fixed temperature (the basic station observes four times a day, and the four hours are 02, 08, 14 and 20 respectively; According to the actual situation, some stations observe three times a day, at 08: 00, 14 and 20: 00 respectively. Reference station observation 24 times a day), as well as the daily maximum and daily minimum temperature.

Usually, people use the numerical value of atmospheric temperature to reflect the degree of heat and cold of the atmosphere. China uses centigrade scale, which is expressed in℃ and pronounced as℃.
