What is Wind?
Wind- the movement of air from an area of high pressure (more dense) to an area of low pressure (less dense).

Different Pressure is caused by the uneven heating of the Earth’s surface.
High Pressure COLD AIR-
contracts and is more dense, so it sinks
Low Pressure WARM AIR-
expands and is less dense so it rises.

Do Now
In your journal, provide an example of conduction, convection and radiation. Then, answer this question.
1. Do you think the Earth’s surface is heated evenly?
Why or why not?

Winds do not just blow from N to S…Why?
Coriolis Effect- the spinning of the Earth that causes wind and water to be deflected right and left

Global Winds
Polar Easterlies- cold winds in the polar region that move from EAST to WEST
Westerlies- winds from the west that moves towards poles. Moves weather systems across the
United States
East Trade Winds-winds that move from the east to the west.
Doldrums- windless zones near the equator because the hot air rises

Do Now
On the back of your wind notes, define land breeze and sea breeze using the book’s glossary.
Then use page 1o7 to draw a picture of the land and sea breeze.
Make sure you use arrows and labels in your pictures.
