General Information on Wind

Wind is the horizontal movement of air from areas of high pressure to areas of low pressure. Wind is caused by differences in air pressure.

  • Cold air blows from the North and South Poles and warm air blows from the equator


Doldrums:
  • Winds that blow at the equator and are very weak.


Trade winds:
  • Between 0 degrees and 30 degrees latitude and are very strong
  • Sailors use these winds to help them carry cargo to other countries to trade goods
