Temperature distribution law and its influencing factors

The distribution law of temperature and its influencing factors are as follows:

Distribution law of world temperature

1. Distribution law of world temperature: the isotherm is banded along latitude, and the temperature gradually rises from low latitude to high latitude. The higher the latitude, the lower the temperature.

2. In the same latitude zone, the temperature on land is higher than that on the sea in summer, and the temperature on the sea is higher than that on land in winter.

3. The temperature decreases with the elevation, and the temperature decreases by 0.6 per 100 meter.

Five factors affecting temperature

1, latitude position. Usually the equatorial region has the most precipitation, and the precipitation near the poles is the least. Near the Tropic of Cancer, there is more precipitation on the east coast of the mainland and less precipitation on the west coast. Generally, the lower the latitude, the higher the temperature and the higher the latitude, the lower the temperature.

2. Atmospheric circulation. It is the main factor that forms various climate types and weather changes. The manifestations of atmospheric circulation include planetary wind system, monsoon circulation, land-sea wind and valley wind. What people usually call atmospheric circulation mainly refers to planetary wind system.

3. Land and sea distribution. The distribution of land and sea changes the zonal distribution of temperature and precipitation. Due to the different physical properties of the ocean and the land, under the strong sunlight, the ocean heats up slowly, while the land heats up rapidly. After the sun weakens, the ocean cools slowly, while the land cools rapidly.

4. Terrain. Terrain is a non-zonal factor, and different landforms have different effects on climate. In the same latitude zone, the higher the terrain, the lower the temperature, and the precipitation increases with the height within a certain height range. There is more precipitation on windward slope and less precipitation on leeward slope in mountainous area.

Climate, a natural science term, refers to the multi-year average state of the atmosphere in a region. The main climatic factors include light, temperature and precipitation, of which precipitation is an important factor. The climate types in China are tropical monsoon climate, subtropical monsoon climate, temperate monsoon climate, temperate desert climate, temperate grassland climate and alpine plateau climate.

Climate is a long-term average state of atmospheric physical characteristics, which is different from weather and has certain stability. According to the World Meteorological Organization (WMO), a standard climate calculation time is 30 years. Climate is measured by the characteristics of cold, warm, dry and wet, and is usually characterized by the average value and deviation value of a certain period.
