The trade winds particularly in the western Pacific and Southern Indian oceans are stronger in winter than summer but the seasonal contrast is much less than those of the mid-latitude storm track. In the East China Sea particularly through the Taiwan and Luzon Strait the strong E is caused by the winter monsoon. In the Arabian Sea and Bay of Bengal it is caused by the summer monsoon. In the South China Sea the wind has two peaks both in summer and winter. QuikSCAT data also reveal detailed wind structures not sufficiently identified before. The strong winds of transient tropical cyclones are not evident in E derived from the seven-year ensemble. Because space sensors measure stress the distribution reflects both atmospheric and oceanic characteristics. Regions of high E associated with the acceleration of strong prevailing winds when defected by protruding landmasses are ubiquitous. Less well-know examples such as the strong E found downwind of Cape Blanco and Cape Mendocino in the United States and Penisula de La Guajira in Columbia stand out even on the global map. Strongest E is observed when the along-shore flow coming down from the Labrador Sea along the west Greenland coast as it passes over Cape Farewell meeting wind flowing south along the Atlantic coast of Greenland. Strong E is also found when strong wind blows offshore channeled by topography. The well-known wind jets through the mountain gap of Tehuantepec in Mexico and the Mistral between Spain and France could be discerned in the figures. Alternate areas of high and low E caused by the turbulent production of stress by buoyancy could also be found over mid-latitude ocean fronts with strong sea surface temperature gradient .
