Apart from precipitation, what are the three influencing factors of temperature?
(1) location: including latitude location and land and sea location. ① Influence of latitude on temperature: The global temperature decreases from low latitude to high latitude. Such as heat, temperature and cold. (2) Influence of land and sea distribution on temperature: Due to the difference of thermal properties between land and sea, the temperature changes moderately in areas greatly affected by the ocean; On the contrary, it is affected by the land. For example, the temperate maritime climate is mild all year round, while the temperate continental climate is hot in summer and cold in winter.
(2) Atmospheric circulation: ① Frontal activity: mainly refers to the influence of cold (warm) front on temperature before, during and after transit. For example, the cold front is controlled by the warm air mass before crossing the border, and the temperature is high; Cold front crossing, strong wind cooling; After the cold front passes through the border, it is controlled by the cold air mass and the temperature is low. Warm front is opposite. ② Weather conditions: It is cloudy during the day, and the temperature is often lower than that in sunny days due to the strong weakening effect of the atmosphere on solar radiation; Cloudy at night, because of the good insulation effect of the atmosphere, it is often warmer than a sunny night; On cloudy days, the temperature difference between day and night is often small, but on sunny days, it is the opposite.
(3) Terrain: Because the temperature in the troposphere decreases with the elevation, the higher the terrain, the lower the temperature in the same hot zone. In addition, the tall terrain often blocks the cold air, so the temperature in mountain basins and valleys is often very high.
(4) Ocean current: Warm current can increase temperature and humidity, while cold current can decrease temperature and humidity.
(5) Vegetation: mainly refers to vegetation coverage. In areas with high vegetation coverage, the temperature change is less than that of bare land because of its shielding effect on solar radiation and its influence on evaporation.
(6) Hydrology: Lake area, reservoir area, swamp and wetland have large heat capacity, so the temperature difference is small.
(7) Human activities: urban heat island effect, atmospheric greenhouse effect, human afforestation and deforestation, reservoir construction, lake reclamation, etc.
