What are Westerlies?

Westerlies blow from Sub-Tropical High-Pressure Belts to Sub-Polar Low-Pressure Belts between 30° and 60°N of the Equator in the temperate latitudes.

  • Because of the Coriolis Effect, they deflect to their right to become the South Westerlies in the Northern Hemisphere and deflect to their left to become the North Westerlies in the Southern Hemisphere.
  • They are strong winds that are dominated by the movements of cyclones and anti-cyclones.
  • They are responsible for carrying warm equatorial waters and winds to the western coasts of the temperate lands.
  • Because of the shifting of the wind systems, not all the places located on the western coast of the temperate lands receive rainfall throughout the year.
