Warm air toward high latitudes and cool air toward the equator
The Hadley cell is the convection cell in the atmosphere that borders on the intertropical convergence zone (ITCZ). In this region, warm air rises at the equator, creating a low-pressure area, while cooler air descends at around 30 degrees latitude, creating a high-pressure area. This circulation pattern plays a key role in driving global atmospheric circulation and weather patterns.

Northeast trade winds are a dominant wind pattern in the Northern Hemisphere that blow from the northeast towards the equator. These winds are particularly strong and consistent near the equator due to the Coriolis effect, playing a key role in shaping global weather patterns and affecting maritime navigation.
The 7 components of the general circulation pattern in the atmosphere are: the Intertropical Convergence Zone (ITCZ), the subtropical highs, the subpolar lows, the polar highs, the polar easterlies, the westerly winds, and the jet streams.
The circulation pattern cells near the equator are the Hadley cells. These cells involve warm air rising near the equator, moving towards the poles at upper levels of the atmosphere, cooling and sinking around 30 degrees latitude, and returning towards the equator near the surface. This creates a continuous loop of air movement in the tropical regions.
The dominant pattern of surface circulation on Earth is the Hadley cell circulation, which is driven by the temperature difference between the equator and the poles. This circulation pattern involves the rising of warm air at the equator, spreading towards the poles at high altitudes, descending at around 30 degrees latitude, and returning towards the equator at the surface.

Warm air toward high latitudes and cool air toward the equator
The Hadley cell is the convection cell in the atmosphere that borders on the intertropical convergence zone (ITCZ). In this region, warm air rises at the equator, creating a low-pressure area, while cooler air descends at around 30 degrees latitude, creating a high-pressure area. This circulation pattern plays a key role in driving global atmospheric circulation and weather patterns.
The model commonly used to describe air circulation is the Hadley cell model. This model explains the global pattern of atmospheric circulation, including the movement of warm air towards the poles and cool air towards the equator.
Global air circulation between the equator and the poles is primarily driven by the uneven heating of the Earth's surface by the Sun. The equator receives more direct sunlight, causing warmer air to rise, while cooler air at the poles sinks. This creates a circulation pattern known as the Hadley, Ferrel, and Polar cells, which redistribute heat and moisture around the planet. Additionally, the Coriolis effect, caused by the Earth's rotation, influences wind direction and contributes to the complex patterns of global air circulation.

Generally, the fattest part of the Earth -- the Equator -- breaks up the general rotational pattern of the atmosphere.
Northeast trade winds are a dominant wind pattern in the Northern Hemisphere that blow from the northeast towards the equator. These winds are particularly strong and consistent near the equator due to the Coriolis effect, playing a key role in shaping global weather patterns and affecting maritime navigation.
The 7 components of the general circulation pattern in the atmosphere are: the Intertropical Convergence Zone (ITCZ), the subtropical highs, the subpolar lows, the polar highs, the polar easterlies, the westerly winds, and the jet streams.
If the Earth did not rotate, global winds would follow a north-south path from the poles to the equator, due to the temperature difference between the poles and the equator. This wind pattern would be known as the Hadley cell circulation.
