These three things determine what kind of air mass will form.
What are temperature, humidity and air pressure?
200
This air mass forms over warm water.
What is maritime tropical air mass?
200
You are looking at a map and you see the symbol mP. This air mass is present at that location.
What is maritime polar?
200
This front is represented by blue triangles on a weather map.
What is a cold front?
200
This front forms when a cold air mass slides under a warm air mass and lifts it up to forms clouds.
What is a cold front?
200
This air mass can bring warm, dry air in the summer.
What is a continental tropical air mass?
300
This air mass froms over land that is cold.
What is continental polar air mass?
300
This air mass forms over cold water.
What is maritime polar air mass?
300
This front forms when warm air slides over cold air.
What is a warm front?
300
This front forms when a cold air mass meets a cool air mass with a warm air mass in the middle. The warm air mass gets cut off from the ground and is forced upward to create clouds.
What is an occluded front?
300
Once these two fronts are formed, they move slowly (one barely moves).
What are a warm front and a stationary front?
400
This air mass can bring hot, humid weather in the summer.
What is maritime tropical air mass?
400
You are looking at a map and you see the symbol cT. This air mass is present at that location.
What is continental tropical?
400
This front is represented by purple triangles and circles all going the same direction.
What is an occluded front?
400
This air mass is represented by red circles and blue triangles. The circles and triangles are facing opposite directions.
What is a stationary front?
400
These two things move air masses.
What are prevailing westerly winds and the jet stream?
500
This air mass can bring heavy snow in the winter.
What is maritime polar?
500
This air mass can bring cold dry air.
What is continental polar air mass?
500
This front is when a cold air mass meets a warm air mass and neither one move.
What is a stationary front?
500
All fronts bring this.
What is precipitation?
500
This front is very fast moving. It is past within 1-2 days.
