Unlike the westerlies in the middle latitudes, the polar easterlies are often weak and irregular. West winds are winds that flow from subtropical high-pressure belts to sub-polar/circumpolar low-pressure belts. Whenever there is a convergence of the cold and denser polar winds and warm and light westerlies, there are much variation in the weather. Due to this reason, the westerlies blow with much greater force in southern hemisphere in comparison to northern hemisphere.
