Factors affecting temperature

Factors affecting temperature: location, atmosphere, topography, ocean currents, vegetation, hydrology and human activities.

I. Location:

Include latitude position and land and sea position. The influence of latitude position on temperature: the global temperature decreases from low latitude to high latitude. The influence of land and sea position on temperature: the temperature changes little in the areas affected by ocean and land, and the main reason for the temperature change is the difference of thermal properties between land and sea.

Second, the atmosphere:

Include important weather system and weather conditions. On cloudy days, the atmosphere has a strong weakening effect on solar radiation, and the temperature on cloudy days at night >: the temperature on sunny days, and on cloudy days at night, the atmosphere has a good heat preservation effect, so the temperature difference between day and night on sunny days >; Temperature difference between day and night when it is cloudy.

Third, the terrain:

The temperature decreases with the increase of height. Every time the height in the troposphere rises1000m, the temperature drops by 6℃. Generally speaking, the temperatures in basins and valleys are higher than those in the same latitudes. The high ground blocks the cold air. On the same height mountain, the temperature of sunny slope is slightly higher than that of shady slope. Reason: the amount of solar radiation received by sunny slopes is greater than that received by shady slopes.

Four, ocean currents:

Warm current increases temperature and humidity, while cold current decreases temperature and humidity.

Verb (short for verb) Vegetation:

The temperature change of bare land is higher than that of high vegetation coverage area. Areas with high vegetation coverage have a strong blocking effect on solar radiation.
