Prevailing Winds

Prevailing

WindsAKA: 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.
