Why do permanent pressure belts migrate?

Permanent pressure belts migrate due to seasonal changes in temperature and atmospheric circulation patterns. During different seasons, the heating and cooling of land and ocean surfaces can shift the position of these belts, leading to variations in wind and weather patterns. This migration is particularly influenced by factors such as the tilt of the Earth's axis, solar radiation, and the distribution of continents and oceans. As a result, pressure belts can move north or south, impacting climate and weather systems in various regions.
