How can the degree of hot or cold weather be expressed in terms of how high or low it is?

The degree of hot or cold weather can be expressed by the temperature.

Temperature records can characterize the thermal conditions of a place and are indispensable both in theoretical research and in applications in national defense and economic construction. Temperature is one of the conventional elements to be measured in surface meteorological observations. The temperature has regular temperature (the basic station observes 4 times a day, at 02, 08, 14, and 20).

Influencing factors of temperature:

1. Latitude ( Determining factors):

Affects solar height, day length, solar radiation, daily and annual temperature range (the daily and annual temperature range in low latitudes is smaller than that in high latitudes)

2. Terrain (height, terrain):

Shady slopes, sunny slopes, mountains, plains, valleys, basins at different altitudes (for example: valley basin terrain heat is not easy to dissipate, tall terrain is difficult for winter) Wind blocking, mountainous areas at the same latitude have smaller daily and annual temperature ranges than plains, etc.)

3. Sea and land location:

The strength of oceanicity causes changes in annual temperature range. /p>

4. Ocean currents:

Warm currents: warming and humidification; cold currents: cooling and humidification.

5. Weather conditions:

Clouds and rain. The daily and annual temperature ranges in places with more rain are smaller than those in places with less clouds and rain.

6. Underlying surface:

Ground reflectivity (ice and snow reflectivity is high, temperature is low); green space temperature. The daily and annual differences are smaller than those of bare soil.
