The wind direction and season of each continent control its pressure change.

The distribution of names is caused by the influence of airflow movement on climate.

The equatorial low-pressure area near 0 is heated and expanded, and it is hot and rainy.

The subtropical high belt sinks under the dynamic action of 30 degrees north and south latitude, and is dry and hot under the action of air gravity.

The dynamic action of the sub-polar low pressure belt near 60 north and south latitude makes the cold and warm air flow meet, and the warm air flow rises moderately and humid.

The thermal action near 90 degrees north and south latitude makes the polar high pressure zone cool and sink, and become cold and dry.

Influence of wind direction on climate

Northern Hemisphere Southern Hemisphere

Low latitude trade wind area 0-30 degrees northeast wind southeast dry heat.

Mid-latitude westerly belt 30-60 degrees southwest wind northwest wind warm and humid.

The polar easterly winds are 60-90 degrees, and the northeast winds and southeast winds are cold and dry.

★2. Seasonal movement of pressure belt and wind belt: Due to the seasonal movement of the direct point of the sun, the pressure belt and wind belt also move with the seasons. As far as the northern hemisphere is concerned, it generally moves north in summer and south in winter. (moving with the movement of the direct point of the sun)
