The globe is surrounded by 6 major wind belts, three in each hemisphere. Stretching from the poles to the equator, they are the polar easterlies, the westerlies, and the trade winds.
Global Convection currents
Global ConVection Currents set ConVection currents in motion, particularly a horizontal motion. Large scales of global convection causes global winds. Small scales of global convection cause local winds.
The Coriolanus Effect
The Coriolanus Effect is affected by the earths rotation. It deflects light among a north-south path or longitinal line.
Global Wind Belts
- Polar Easterlies- From 60-90 degrees latitude
- Prevailing Westerlies- From 30-60 degrees latitude
- Tropical Easterlies- From 0-30 degrees latitude
Water near the equator where there is little to no wind at all.
Regions located at about 30 degrees north and south of the equator. These latitudes are associated with winds and little precipitation.
Winds that blow from 30 degrees latitude to the equator, 0 degrees latitude.
Wind belts that extend from the poles to 60 latitude in both hemispheres. They form cold, sinking airs that can create cold, freezing weather within the United States such as snow.
Strong upper level winds within the troposphere and westerlies. It is basically geostophic flow based off of a lack of friction. The winds are stronger in areas such as the north and south poles because of the temperature difference. The winds may reach up to 75-125 mph but are not as strong during the summertime.
