Influence of physical geography atmospheric circulation on climate

Influence of atmospheric circulation on climate formation

1. Different climates are formed under the control of different pressure belts and wind belts.

2. Principles to be grasped in the influence of pressure zone and wind zone on climate:

(1) The seasons can be determined according to the positions of the pressure belt and the wind belt, and conversely, the movements and positions of the pressure belt and the wind belt can be determined according to the seasons.

(2) General principle: rainy and sunny, wet and dry in the west wind.

There are many rainy days in areas affected by low pressure zone and westerlies. How sunny the weather is in the area controlled by the high pressure belt;

The western and central parts of the mainland affected by the trade winds are generally sunny and dry, while the eastern part of the mainland brings water vapor and more precipitation due to the trade winds on the warm ocean.

(3) Due to the influence of single pressure belt and wind belt, there is little difference in climate seasons; Air pressure and wind belt are alternately controlled, and the climate varies greatly in different seasons.

(4) The three-circle circulation mainly affects the west coast of the mainland, while the monsoon circulation mainly affects the east coast of the mainland.
