Precipitation factor

(1) Location: It is mainly the influence of land and sea location on precipitation, and the mainland area is usually dry with little rain.

(2) Atmosphere: It mainly includes the influence of atmospheric circulation, front, cyclone (anticyclone) and other factors on precipitation.

(3) Terrain: there is more precipitation on windward slope and less precipitation on leeward slope; High terrain will also prevent water vapor from entering. For example, the reason for the dry climate in Xinjiang is not only the inland depths, but also the blocking of water vapor by the surrounding mountains.

(4) Ocean current: Warm current can warm and wet coastal climate; The cold current flowing through the coastal climate can reduce temperature and humidity. For example, the desert in Australia extends to the vast area on the west coast of the mainland, which is not only controlled by the subtropical high, but also affected by the trade winds and the cold current in Western Australia. For another example, the seaports of Britain and Norway benefit from the warm current of the North Atlantic because they are not frozen all year round.

(5) Vegetation and hydrological conditions: In areas with high vegetation coverage and around lakes, swamps and reservoirs, the air humidity is relatively high and the relative precipitation is relatively high.

(6) Human activities: the urban wet island effect is that many updrafts in the city are easy to form clouds and cause rainfall; The rain island effect is that the city has more dust, more condensation nuclei, more fog and low clouds than the effective area.
