Question

give reason : major pressure and wind belts moves poleward during the summer season.

Answer 2

Answer:

this due to the revolution of the Earth on an inclined axis which causes an apparent migration of the Sun. During summer season the Sun shines in the Northern hemisphere especially on the tropic of cancer on 21st June.Since the sun shines in the northern hemisphere there is low pressure in the northern region . As wind moves from low pressure region to high pressure region and the low pressure region is near the north pole ,so the wind and pressure belts both shift polewards during the summer season.
