The Equatorial Low-Pressure Belt, often called the Intertropical Convergence Zone (ITCZ), generally extends from the equator to about 10° North and 10° South latitude. Within this zone, intense heat causes air to expand and rise vertically, creating a consistent belt ...

There are seven distinct pressure belts on Earth. These include one Equatorial Low-Pressure Belt, two Subtropical High-Pressure Belts (30° N/S), two Subpolar Low-Pressure Belts (60° N/S) and two Polar High-Pressure Belts at the poles. These belts are the result of ...
All these statements accurately describe the “diurnal” (daily) behavior of the atmosphere. Just as the moon causes ocean tides, solar heating causes “barometric tides”—regular rises and falls in pressure. These cycles are most intense in the tropics, weaken as you ...
Cyclones and anticyclones are classified as secondary atmospheric circulations. While “primary” circulations (like the Hadley Cell) are global and permanent, secondary circulations are smaller, regional and temporary. They are the individual high and low-pressure systems that move across the planet, ...
The “Limb” of the Earth is the visual edge of the planet’s atmosphere against the blackness of space as seen from an orbiting satellite or the moon. It appears as a thin, glowing blue arc. This perspective allows scientists to ...
