global winds over the united states blow in which direction?
blow from the west
the westerlies or the prevailing westerlies are the prevailing winds in the middle latitudes (i.e. between 35 and 65 degrees latitude), which blow in areas poleward of the high pressure area known as the subtropical ridge in the horse latitudes. these prevailing winds blow from the west to the east, and steer extra-tropical cyclones in this general direction. the winds are predominantly from the southwest in the northern hemisphere and from the northwest in the southern hemisphere. they are strongest in the winter when the pressure is lower over the poles, such as when the polar cyclone is strongest, and weakest during the summer when the polar cyclone is weakest and when pressures are higher over the poles.
prevailing winds
in meteorology, winds are often referred to according to their strength, and the direction from which the wind is blowing. short bursts of high-speed wind are termed gusts. strong winds of intermediate duration (around one minute) are termed squalls. long-duration winds have various names associated with their average strength, such as breeze, gale, storm, and hurricane. wind occurs on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption of solar energy between the climate zones on earth. the two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (coriolis effect). within the tropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. in coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can dominate local winds.
