At about sixty degrees latitude in both hemispheres, the prevailing westerlies join with polar easterlies to reduce upward motion. The polar easterlies form when the atmosphere over the poles cools. This cool air then sinks and spreads over the surface.

Polar Easterlies: From 60-90 degrees latitude. ... Prevailing Westerlies: From 30-60 degrees latitude (aka Westerlies). ... In time, hurricanes move into the middle latitudes and are driven northeastward by the westerlies, occasionally merging with midlatitude frontal systems.

In each hemisphere, the windbelts include the Trades, Westerlies, and Polar Easterlies. The pressure cells include the Equatorial Low (ITCZ), and, in each hemisphere, the Subtropical High, Upper-Midlatitude Low, and Polar High.

The WESTERLIES are located in both hemispheres between the polar easterlies and the trade winds. Air that continues moving towards the poles from the horse latitudes instead of moving back towards the equator to form the trade winds are basically what produces the westerlies.

The Westerlies blow between 30 and 60 degrees North and South. The Westerlies blow between the increasing pressure at the equatorial Trade winds and the decreasing pressure at the Polar Easterlies. The Westerlies move to the north and are bowed to the right because of the Coriolis force.

Surface winds known as "westerlies" flow from the Horse Latitudes toward the poles. The "westerlies" meet "easterlies" from the polar highs at about 50-60° N. and S.
