Wind
By Nick Gagliardi
General Information on Wind
- Wind is the movement of air
- It's caused by unequal heating on Earth's surface
Global Winds
- Global winds are wind that occur in large areas
- They're caused by a combination of pressure belts and the Coriolis effect
- Global winds happen when warm air rises and cold air fills it in
- The cold air filling the warm air in is the wind
- Air is always trying to get the equator (warmest area) until it heats up enough to rise up
- Coriolis effect causes the winds to curve
Doldrums
- Area on the equator where there are no winds
- Sailors can get stuck there
Prevailing Westerlies
- Winds between 30 and 60 degrees latitude
- Winds blow across America and slightly towards the poles
Trade Winds
- Winds from 0 to 30 degrees latitude
- The cooler air from blows to fill in the warmer air that rises near the equator
Polar Easterlies
- Winds from 60 to 90 degrees latitude
- Cold air from poles travel to equator until warm enough to rise again

Local Winds
- Winds that occur in small areas
- Are caused by unequal heating on Earth's surface
Sea Breeze
- Type of local wind that happens near shoreline during the day
- Warmer air over the land rises and cooler air over the ocean fills it in
- The cooler air is the wind
Land Breeze
- Type of local wind that occurs near the shoreline during the night
- Warmer air over the ocean rises and the cooler air over the land fills it in
- The cooler air over land filling it in is the wind
