At the end of class, you will be able to: Relate air pressure and wind direction Explain why winds flow in a curved direction Discern global winds from local winds Describe the three main global wind patterns on Earth Explain two types of local wind patterns
Why doesn’t wind blow directly from the poles to the equator?
Thought to consider: is the Earth in a fixed position?
Wind movement affected by Earth’s rotation Results in a curved path of motion Depends on hemisphere you are in Northern hemisphere- winds curve to the right Southern hemisphere- winds curve to the left
The Coriolis effect is the curving motion of objects caused by the Earth’s rotation
Global winds Pattern of circulation across the Earth Travel great distances Travel in a specific direction Local winds Travel short distances Can blow from any direction
