planetary wind system
Quick Summary
Planetary wind systems, also known as atmospheric circulation, are large-scale wind patterns that encircle the Earth. These systems are driven by differences in atmospheric pressure, which are influenced by solar heating and Earth's rotation.123
Key components include:
* Trade Winds: Blow westward and equatorward from subtropical high-pressure belts near 30° N and S latitudes towards the equator.14
* Westerlies: Flow eastward and poleward from the subtropical high-pressure belts in the mid-latitudes.15
* Polar Easterlies: Generally blow westward and equatorward from polar regions.1
The Coriolis force, an apparent deflection caused by Earth's rotation, significantly influences these wind patterns, causing air to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. These global wind belts are more uniform in the Southern Hemisphere due to less landmass interference.341
