This air mass forms over land near the equator
Continental tropical air mass
A front is a _________ between two air masses.
Boundary
This front is represented by red circles.
A warm front
These two things determine what kind of air mass will form.
temperature and humidity
This air mass forms over water near the equator
Maritime tropical air mass
You are looking at a map and you see the symbol mP. What kind of air mass is present at that location.
Maritime polar
This front is represented by blue triangles on a weather map.
A cold front
This front forms when a cold air mass slides under a warm air mass and lifts it up to forms clouds.
A cold front
What weather instrument is used to measure atmospheric pressure?
Barometer
This air mass forms over land near the poles.
Continental polar air mass
You are looking at a map and you see the symbol cT. This air mass is present at that location.
Continental Tropical
This front forms when warm air slides over cold air.
A warm front
This front forms when a cold air mass meets a cold air mass with a warm air mass in the middle.
An occluded front
What directions do warm air masses tend to approach from?
S, SE, E
As air cools, it becomes more dense and sinks toward the Earth’s surface spinning clockwise.
High atmospheric pressure
As air warms, it becomes less dense and rises above the Earth’s surface spinning counterclockwise.
Low atmospheric pressure
This front is represented by purple triangles and circles all going the same direction.
Occluded front?
This air mass is represented by red circles and blue triangles. The circles and triangles are facing opposite directions.
A Stationary front
What directions do cold air masses tend to approach from?
N, NW, W
This air mass forms over water near the poles
Maritime polar
A line connecting points of equal atmospheric pressure
Isobar
This front is when a cold air mass meets a warm air mass and neither one move.
A stationary front
High atmospheric pressure brings what kind of weather?
Sunny clear skies
Low atmospheric pressure brings what kind of weather?
Cloudy stormy skies
