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.
High pressure belts found at 30 degree latitudes are called subtropical high-pressure belts. These belts are generated by the sinking air from the Hadley Cell circulation at these latitudes, resulting in stable atmospheric conditions and clear skies. Subtropical high-pressure systems are associated with arid climates and are often responsible for the formation of deserts.

Stable, Permanent.
It is the temperature which controls the pressure belts and ,therefore, as the sun moves from one tropic to another, the pressure belts also do the same.This phenomenon is called as shifting of pressure belts.
The pressure belts are located at different latitudes rather than longitudes. Some of the main pressure belts include the equatorial low-pressure belt near the equator, the subtropical high-pressure belts around 30 degrees north and south latitudes, and the subpolar low-pressure belts near the poles.
Its caused by the combination of pressure belts and the Coriolis effect.
Because high pressure belts have sinking motion and dry conditions. Low pressure belts have rising motions and havey rainfall. pce

The deserts in Africa are primarily influenced by the subtropical high-pressure belts located at around 30 degrees North and South of the equator. These high-pressure zones create stable atmospheric conditions that inhibit cloud formation and precipitation, resulting in arid conditions in places like the Sahara and Kalahari deserts.
The convection cells radiate heat.
Pressure belts are formed in the atmosphere due to the unequal heating of the Earth's surface. The sun's rays are more concentrated near the equator and spread out towards the poles, which creates temperature differences and leads to variations in air pressure. This results in the formation of different pressure belts like the equatorial low-pressure belt and the subtropical high-pressure belts.
