General Wind
- wind is created unequal heating of Earths surface
- wind always blows from an area of high pressure to an area of low pressure
- there are 2 types of wind global winds and local winds
Local Winds
- local winds change direction and speed frequently
- local winds cover a small area
- there are 2 types of local winds land breezes and sea breezes
- land breezes blow from the land to the sea and occur during the night time
- sea breezes blow from the sea to the land and occur during the daytime
Global Winds
- global winds almost never change direction or speed
- global winds cover massive amounts of the earth
- examples of global winds are Trade Winds, Prevailing Westerlies, Polar Easterlies, Jet Streams
- Trade winds blow towards the equator from the Horse Latitudes
- when traveling north they turn towards the left and when traveling south the winds turn toward the right
- Trade winds received there name when traders sailed through those parts so the could trade
- the Horse Latitudes are areas of calm winds or no wind at all
- the Horse Latitudes got their name from ships caught in these calm wind areas had to throw horses over board
- prevailing westerlies blow from the Horse Latitudes to the North and South poles
- Jet Streams travel from west to east
- the Jet Streams can span over miles but are only a couple of meters high
- pilots use the Jet Streams to get to places faster
