1. Global Winds:
How global winds affect weather patterns

2. Global Winds
- A current is a flow of air or water in a certain direction.

3. Global Winds Winds move from areas of high pressure to low pressure.
You might expect them to move straight from the poles (high pressure) to the equator (low pressure)but…

4. Global Winds
-The paths of global winds curve because earth is spinning on an axis.
- This is called the Coriolis effect.

5. Global Winds
-In the northern hemisphere winds traveling north curve to the east.
-Winds traveling south curve to the west.
-Weather forecasters use this information to predict how air masses will move.

6. -Polar Easterlies are winds that blow from east to west between 60 degrees and 90 degrees latitude.
-Prevailing Westerlies are winds that blow West to East between 30 degrees and 60 degrees latitude.

7. -Trade Winds are winds that blow from east to west between o degrees and 30 degrees latitude.
-The doldrums are the area directly at the equator where there is no wind at all.

8. -The Prevailing Westerlies primarily affect the weather in the US.
-This is why air masses move from West to East in the US.
