what is wind?

wind is natural movement of the air.wind is caused by differences in the atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator.

local winds

  • a local wind is a type of wind
  • a local wind is caused by unequal heating of the earths surface
  • land breeze blows closer to the ground
  • since sea takes longer to cool it will rise higher than the land did

global winds

  • global winds are comprised of three prevailing winds :Trade winds, Westerlies, and Polar Easterlies.
  • All wind is caused by the uneven heating of Earth's surface, which sets convection currents in motion. Convection currents on a large scale cause global winds
  • the ocean's near the Doldrums are very calm
  • the trade winds are winds blowing from the north to the south
