The Earth's rotation turns the polar high pressure systems westward as they move from the poles (westerlies), and the subtropical high pressure systems eastward as they move toward the equator (tropical easterlies).
The equators warm air, and the polar cold air.
Wind currents flow faster at the poles than at the equator. This is due to the Coriolis effect, which causes the winds to be deflected as they move from high pressure to low pressure areas, creating stronger winds at higher latitudes. Additionally, temperature differences between the equator and the poles contribute to the strength of wind currents.
Global air convection currents are primarily driven by the uneven heating of the Earth's surface by the sun. Near the equator, the sun's rays are more direct, causing warm air to rise and create low pressure. As this warm air moves poleward, it cools and sinks, creating high-pressure areas near the poles. The rotation of the Earth (Coriolis effect) also influences these currents, leading to the formation of distinct wind patterns, such as the trade winds and westerlies.

Global air convection currents are primarily driven by the uneven heating of the Earth's surface by the sun. Near the equator, the sun's rays are more direct, causing warm air to rise and create low pressure. As this warm air moves poleward, it cools and sinks, creating high-pressure areas near the poles. The rotation of the Earth (Coriolis effect) also influences these currents, leading to the formation of distinct wind patterns, such as the trade winds and westerlies.
Causes air to move from poles toward the equator
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.
After high-pressure areas are formed around the poles, cold polar air flows towards lower pressure regions. This movement of air is known as advection, and it helps to balance out the pressure differences between the poles and lower latitudes.
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.
