mean annual temperature

The annual average temperature is a forestry term published on 20 16.

Is it cold in Beijing all year round? What is the average annual temperature in Beijing? 9℃? ~? 19℃。

The average temperature during the day is 19℃, so it is recommended to wear short clothes, T-shirts, thin jeans, casual clothes, professional clothes and other comfortable clothes.

Night average? 9℃? It is recommended to wear warm clothes such as suits, coats, jackets, jackets and thin sweaters.

The city with the highest annual average temperature in Beijing is Haidian (19℃? ), Chaoyang (19℃? ), Shunyi (19℃? ), Huairou (19℃? )。

The city with the lowest annual average temperature in Beijing is Yanqing (5℃? ), Miyun (6 C? ), Huairou (7 C? ), Pinggu (7 C? )。

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.

Definition:

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℃.
