1. Today Hand in any work needed. Check the list, if you owe something.
Get out a small piece of paper, PUT YOUR NAME ON IT.
When bell rings the quiz will start and you will have 1 minute per question to answer

2. Mini Quiz What do we use to measure Humidity?
Sling Psychrometer
If the DB=0oC & WB=-5oC, what is the:
Dew Point
Humidity
Dew Point -24oC
Humidity 11%
What is the Humidity if DB=4oC DP=4oC
100%
What happens as the temperature and Dew Point meet?
Clouds condense

3. Wind
The movement of air.

4. What causes wind? Caused by: Cooler air is more dense than warm air.
Heat flow (difference in temperatures)
Pressure differences
Cooler air is more dense than warm air.

5. Pressure gradient Wind blows from High to Low pressure.
The greater the difference between H and L the stronger the wind.

6. Types of wind Breezes Coriolis Effect Prevailing wind
Water temperature differences causes wind. (specific heat differences)
Wind is named for where it came from.
Coriolis Effect
Prevailing wind

7. Breezes Land breezes Sea Breezes
Air rises off the water condenses into clouds forcing air down onto the land.
Usually at night.
Sea Breezes
Air rises off the land forming clouds forcing air down over the water.
Usually during the day.

8. Breezes (draw this)

9. Coriolis Effect
This is the idea that because the Earth is round and rotates daily there is a force that curves wind.
DRAW
Right in the North
Left in the South

10. Coriolis (GLOBE)

11. Prevailing Wind
This is the direction the wind normal moves at the surface.
In NY it is from the North West, in Florida it is from the North East.

12. Diagram (draw) Rules Look at page 14 of your ESRT
Winds blows from high to low pressure
Winds curve to the RIGHT in Northern Hemisphere
Winds curve to the LEFT in the Southern Hemisphere.
Wet means Low pressure
Dry means High pressure
Look at page 14 of your ESRT

14. ESRT pg 14

15. Jet Stream
The Jet stream is a flow of air that flows in the upper atmosphere.
Do not follow surface winds but they do effect the movement of storm systems.

16. Measuring Wind Wind is the flow of air.
Always blows from HIGH to LOW
We measure it with an anemometer.
