Influence of wind on temperature and precipitation

The influence of wind on precipitation is mainly in the wind belt, including polar easterlies, westerly belt and trade belt, while westerly belt and trade belt have great influence on precipitation, and the influence of wind belt on precipitation is mainly through bringing marine water vapor to the mainland to form precipitation; The influence of wind on temperature is mainly concentrated on sensory temperature. One is to enhance human convective heat transfer, and the other is to accelerate air evaporation, thus affecting the heat dissipation efficiency of human sweat.

The special influence of pressure zone and wind zone on precipitation; Pressure zone.

The global pressure zone is formed by thermal or dynamic reasons. High pressure area is common in downward flow. In the process of sinking, the temperature is rising, the saturated content of water vapor is decreasing, and the air is getting drier and drier, so it is difficult to form precipitation, mostly sunny.

For example, in tropical desert areas, controlled by subtropical high, downward flow prevails all the year round, which is hot and dry; Formation of dry weather in summer in the Yangtze River valley of China: In areas controlled by low pressure, updraft is dominant, and updraft cooling is easy to reach supersaturated state, which often condenses rainfall and forms rainy areas, such as equatorial areas, which are controlled by low pressure all year round and rainy all year round.

wind belt

The global wind belt includes polar easterlies, westerlies and trade winds, which have great influence on precipitation. The influence of wind belt on precipitation is mainly formed by bringing ocean water vapor to the mainland.

According to the relationship between the wind belt and the mainland, it can be divided into windward shore and leeward shore. The windward shore is often affected by the water vapor brought by the wind belt from the ocean, and there is more precipitation; The leeward blows from the land to the sea, with dry air and little precipitation.

The west coast of the mid-latitude continent is the windward coast of the west wind, with a lot of precipitation, such as the west coast of Europe and the west coast of North and South America; The east coast of the low latitude continent is the windward shore of the trade winds, with a lot of precipitation, such as eastern Madagascar and northeastern Australia.

The formation of tropical rain forest climate in the southeast of Brazil Plateau is related to trade winds, and the formation of tropical desert climate and tropical grassland climate in the west is related to trade winds blowing from land to sea.
