meteorology
Also known as: easterlies, polar

Quick Summary

The polar easterlies are wind systems that generally blow westward and equatorward, located poleward of 60° N and 60° S. These winds are part of the Earth's general atmospheric circulation, which involves large-scale wind systems arranged in east-west belts. In the Northern Hemisphere, the polar easterlies can be variable due to the mix of land and water, and they may give way to different wind patterns in the summer. In contrast, the Southern Hemisphere's polar easterlies are more uniform because of the surrounding ocean. The strength and behavior of these winds are influenced by pressure systems and seasonal changes.12
