A low pressure belt refers to a region in the atmosphere where the atmospheric pressure is lower than that of surrounding areas, typically associated with rising air. This phenomenon often leads to cloud formation and precipitation due to the cooling of air as it rises. Low pressure belts are commonly found near the equator, such as the Intertropical Convergence Zone (ITCZ), and can influence weather patterns and climate in surrounding regions. These areas are characterized by unsettled weather conditions, including storms and rainfall.
The equator is an intensely heated throughout the year . Due to the intense heating the air in this region becomes warm and light and it rises above creating a partial vacuum .(As you know vacuum leads to decrease in air pressure) As a result a region of permanent low pressure is created called the equatorial low pressure belt.
in equitorial low pressure belt , low pressure is due to 1) intense heating 2) rate of rotation of earth is max. at equator . this results in max centrifugal force at equator which pushes the air away from the surface and causes low pressure condition.
It means low pressure and low pressure means that wherever the L is there will be stormy weather.
The equatorial belt of low pressure and heavy rainfall is called the Intertropical Convergence Zone (ITCZ). This zone is characterized by the convergence of trade winds from both hemispheres, leading to upward motion, cloud formation, and precipitation.
The convection cells radiate heat.

The uneven heating of the earth produces pressure belts. these belts occur at about every 30 degrees latitude. The rotation of the Earth flings the bulk of the air creating an area of low pressure belt in this region.

The low pressure wind belt located in the equatorial regions is called the Intertropical Convergence Zone (ITCZ). This area is known for its rising warm, moist air that creates a belt of low pressure and convergence of trade winds.

The Intertropical Convergence Zone (ITCZ) is characterized by low pressure, as warm, moist air rises and converges near the equator, creating a belt of low pressure.
The only truly continuous pressure belt is the subtropical high-pressure belt located around 30 degrees latitude in both the Northern and Southern Hemispheres. This belt is characterized by relatively stable high pressure due to the sinking air from the Hadley cells.
The equator is an intensely heated throughout the year . Due to the intense heating the air in this region becomes warm and light and it rises above creating a partial vacuum .(As you know vacuum leads to decrease in air pressure) As a result a region of permanent low pressure is created called the equatorial low pressure belt.
