How does air move around a high pressure center in the Northern Hemisphere?
You can write or draw.
Outwards and Clockwise

What is the cloud coverage?
50%
200
This is the amount of water vapor in the air in a particular parcel of air.
Humidity
200
Air pressure is usually highest when the air is both (cool, warm) and (wet, dry).
Cool and Dry

(include units)
29.35 inches
400
What separates the Atmosphere layers?
Differences in temperatures
400
What type of weather occurs at High pressure centers and why?
Happy weather, because of sinking air.
400
What is the current atmospheric pressure? (include units)
1002mb
500
A line drawn on a map to connect areas of equal air pressure.

How do air masses flow?
From areas of high pressure to area of low pressure
500
Why is the Atmosphere important?
(Could be multiple reasons; just write one)
Contains oxygen
Traps heat
Protects us from the suns uv rays
500
What causes Wind?
Air pressure gradients
500
Based on data from the station model, explain how a scientist could infer that there was a high relative humidity.
Air temp and dew point are close together.
