Westerlies are strongest in the winter, when pressure over the pole is low, and weakest in summer, when the polar high creates stronger polar easterlies. the speed, height and direction of the winds in polar regions. The trade winds (also called trades) are the prevailing pattern of easterly surface winds found in the tropics near the Earths equator, equatorward of the subtropical ridge. In the mean in the Northern Hemisphere, these easterlies exist to The currents in the Northern Hemisphere are weaker than those in the Southern Hemisphere due to the differences in strength between the Westerlies of each hemisphere. Oceanographers do the opposite. At about 60 N, part of the air mass rises and moves northward back towards the North Pole at high altitude, creating a band of low air pressure (Fig. Polar easterlies: They are dry and cold prevailing winds that blow from the east.
