Prevailing Winds AKA: Global Wind Belts Where convection cells (air masses) meet forming jet streams and prevailing winds Winds move from a area of high pressure to an area of low pressure.

Easterlies : Polar Easterlies- high altitudes, cold dense air that blows East to West. (from the Poles to the Equator) Trade winds- Low altitudes, blow East to West toward the Equator.

Westerlies: Mid latitudes blow West to East toward the poles.

Other: Pressure belts from inbetween the wind belts Doldrums: along the equator. Heating causes the sir to expand, resulting in cloudy, rainy weather.
