Seasonal movement of wind belt in pressure belt

The law of seasonal movement in this area is that it moves northward in summer and southward in winter all year round. The movement is later than the direct point of the sun 1 month, and the annual movement range is about 10.

Due to the revolution of the earth, the direct point of the sun moves between the tropic of cancer with the change of seasons, which also causes the seasonal movement of the pressure belt and the wind belt.

When the direct point of the sun moves northward, the pressure belt and the wind belt also move northward, and the other moves southward. This motion lags behind the direct point of the sun for about one month, and the motion amplitude is about 10. In summer, the pressure belt and wind belt are northward, and in winter they are southward.
