<P> Doldrums: At about the equator is Intertropical Convergence Zone or doldrums, a region of light and irregular wind broken by occasional thunderstorms and squalls . The width and exact location of the doldrums were hard to predict . Sailing ships are sometimes becalmed here for many days waiting for a proper wind . </P> <P> Southern hemisphere: In the southern hemisphere the belts are reversed . The southeast trade winds blow from the southeast toward the equator . The southern equivalent of the horse latitudes (or Variables of Cancer) is called the Variables of Capricorn . The southern westerlies start somewhat south of South Africa . They tend to be stronger than the northern westerlies because they are mostly over water (roaring forties). The southern polar easterlies are mostly over Antarctica . </P> <P> Seasonal shifts: All of the belts move north during the northern summer and south during the northern winter . Because global heating and cooling lags behind the position of the sun, they reach their northernmost latitude at or after the end of the northern summer . This brought the trade winds within reach of the Spain and Portugal and determined the sailing time of the Spanish treasure fleet . The northernmost position of the wind belts corresponds to the Atlantic hurricane season . </P> <P> Land and sea breezes: Land gains and loses heat more rapidly than water . During the day, the land warms more rapidly than the water . The air above land warms, becomes thinner, and rises, drawing cooler air landward from the sea . At night, the process reverses, and cool heavy air from the land flows out to sea . These land and sea breezes are important along the coast . </P>

How would coriolis effect wind patterns on the surface between the three major latitudes
