Influence of geographical pressure zone and wind zone on climate in senior high school

The planetary wind system includes two groups of low pressure, two groups of high pressure and three groups of wind belts:

The high pressure area is characterized by dry climate, which is caused by the increase of temperature and the decrease of humidity in the descending airflow. The low-pressure area is characterized by humid climate (there is a lot of precipitation in the equatorial low-pressure area);

In the case of wind belt, the wind blowing from high latitude to low latitude is generally dry, because heating will reduce the water vapor capacity of the air. One of the special cases is that if it is lifted by the terrain, there will be a cooling process along the way, and the humid climate is more obvious in some windward slopes of the trade belt: Brazil Plateau, eastern Madagascar, and Central America; If the wind in the wind belt blows from low latitude to high latitude, it will form a humid climate trade zone, that's all.

Trade winds are relatively stable and used to be the maritime power source of maritime trade in history. Climate, they can promote the formation of subtropical monsoon climate, polar front generally appears in the westerly belt and sub-cold belt, which usually brings extreme weather such as snowstorm.
