Winds
By: Morgan Hellman
Wind
Wind is the sideways movement of air. It always moves from an area of high pressure to low pressure. Wind is caused by the unequal heating of earth's surface or uneven air pressure.
Local Winds
Local winds are winds that blow in small areas. They are caused by unequal heating of of earth's surface and it usually happens near lakes or ocean coasts.
Sea Breezes
A sea breeze is a local wind that blows from an ocean. It can also be known as a lake breeze which is the same thing as a sea breeze but just on a lake. It blows from the sea to land.
Land Breezes
A land breeze is a local wind that blows from the land over a lake or ocean. This usually happens at night or in the evening. It blows from land to sea.

Global Winds
Global winds are winds that blow steadily over long distances. Theses winds are caused when the sun heats earth unequally. The sun will sometimes shine directly over the equator but it will only shine a little bit in the Northern Hemisphere therefor, causing uneven air pressure and global winds. Also, sometimes the earth's rotation will make the wind curve causing the Coriolis effect.
Horse Latitudes
Horse latitudes are between 30 and 80 degrees North or South latitude. It is in an area of high pressure. It is a calm area of wind and it is a global wind.
Jet Streams
Jet Streams are very strong winds. They blow from west to east. They are in the upper level of the atmosphere.
Trade Winds
Trade winds blow in the lower atmosphere. They are strong winds just like the jet streams. They blow from 30 degrees north and south latitude right near the equator.
Prevailing Westerlies
They are between 30 and 60 degrees north latitude. They blow from high pressure areas in the horse latitudes towards the poles.
