100
This is what air is made of.
What is molecules?
100
Wind moves from this pressure to this pressure.
What is high pressure to low pressure?
100
Air is moving this direction at the center of a low pressure system.
What is upwards?
100
These clouds produce thunderstorms.
What are cumulonimbus?
100
This front brings brief, heavy storms and cooler weather after it passes.
What is a cold front?
200
Air presses in this direction.
What is all directions?
200
This occurs during the day as warm air rises over land.
What is a sea breeze?
200
This is the type of weather at a high pressure system.
What is clear and sunny?
200
These clouds appear in fair (sunny) weather, but often indicate it will rain within 24 hours?
What are cirrus clouds?
200
This front brings hours of steady rain followed by warmer weather.
What is a warm front?
300
This happens to air pressure as you move upwards in the atmosphere.
What is decreases?
300
These winds move weather systems across the United States.
What are the prevailing westerlies?
300
This is the amount of water vapor in the air.
What is humidity?
300
This is the first step in the formation of clouds.
What is warm, humid air rising?
300
The boundary between two different air masses.
What is a front?
400
This is what happens to air pressure when air is cooled.
What is increases?
400
These winds blow for a long period of time in a steady pattern.
What are global winds?
400
This is why warm air has low pressure.
What is because it is less dense and moving upwards?
400
Stratus clouds are associated with this type of weather.
What is cloudy/light rain?
400
All fronts bring this.
What is a change in the weather?
500
This tool is used to measure air pressure.
What is a barometer?
500
The curving of winds to the right in the northern hemisphere is due to this.
What is the Coriolis effect (or rotation of the earth)?
500
Wind moves this way around a high pressure system.
What is clockwise?
500
This is what most clouds are made of.
What is tiny drops of liquid water?
500
This type of front often first produces cirrus clouds, then stratus clouds and rain.
What is a warm front?
