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.
"Warm air tends to have low pressure. Warm air molecules are more active and thus need more space to move around, thus being less dense." This is true with air aloft. However the surface air. which is the air you feel has the opposite effect. cold air is at a higher pressure than warm air at the surface creating a cycle. This also explains how sea breezes and land breezes form.
The Intertropical Coverance Zone. Or to abbreviate, ITCZ.
Equatorial Low
Air moves from high pressure at the poles towards low pressure at the equator due to the pressure difference. This movement of air creates global wind patterns such as the trade winds near the equator.

Air masses move from the polar regions towards the equator due to the temperature difference between the two areas. Warmer air at the equator rises, creating a low-pressure area, while cooler air at the poles sinks, creating a high-pressure area. This pressure difference causes air to move from high to low pressure, resulting in the general movement of air masses towards the equator.
The 30 degree latitude area is at the high pressure region developed by the sinking air from the Hadley Cell created by the low pressure rising air at the equator. Winds move from high to low pressure areas. The doldrums are located at the equator, this is a low pressure area. When the air sinks at the 30 degree latitude air moves away from the 30 toward the equator and 60 degree latitudes. Since air does not move toward the 30, there is no way to bring the maritime air masses to those desert areas.

Low air pressure typically occurs at the equator (0° latitude) and in the polar regions (around 60-70° latitude). At the equator, air is warm and rises, creating a region of low pressure. In the polar regions, cold air sinks and creates high pressure, resulting in low pressure areas at the surface.
Equatorial Low
Air moves from high pressure at the poles towards low pressure at the equator due to the pressure difference. This movement of air creates global wind patterns such as the trade winds near the equator.
The air pressure difference between the equator and the poles is primarily caused by the temperature difference. Warm air at the equator rises, creating a low-pressure area, while cold air at the poles sinks, creating a high-pressure area. This temperature difference drives atmospheric circulation, resulting in the pressure gradient between the two regions.

No, the Intertropical Convergence Zone (ITCZ) is a region near the equator where the trade winds converge, creating low pressure. As warm, moist air rises in this zone, it can lead to the formation of thunderstorms and heavy rainfall.
