The two characteristics of air masses.
What are temperature and moisture?
100
A type of front made of cold, dense air. Rain, snow, thurnderstorms and sometimes tornadoes are caused by this front. Usually, the precipitation does not last very long.
What is a cold front?
100

True or false: A weather station model will tell you about the type of precipitation that occurs. 

What is false?

100
The capital letter H stands for this on a weather map.
What is a high pressure center?

What is the name of the scale used to rate tornado strength?

What is the fujita scale?

200

An air mass that is dry and forms over land.

What is a continental air mass?

200

The front that forms when two air masses meet and neither one takes over. Often causes many cloudy days to occur in a row.

What is a stationary front?

200

What information does the number of lines or flags on the weather station model give you?

What is a wind speed?

200

On a weather map, this is represented by a blue line with triangles.

What is a cold front?

200

What is the scale used to rank hurricane strength?

What is the saffir-simpson scale?

300
An air mass that forms over the polar regions and is cold.
What is a polar air mass?
300
The type of front formed when a large mass of warm air takes over the cooler air mass. Usually produce rain, fog, or snow that lis light but steady.
What is a warm front?
300

What is the wind speed if the station model has two long lines and one short line?

What is 25?

300
Represented by a small circle that is completely white (not colored in).
What is clear skies?
300

What is the crucial ingredient for a hurricane to form that gives energy to the hurricane?

What is warm water?

400
An air mass that forms over the tropics and is warm.
What is a tropical air mass?
400

The type of lifting that occurs when one air mass forces another air mass upwards. 

What is frontal lifting?

What causes different parts of a cloud to become electrically charged, resulting in lightning? 

What is updrafts and downdrafs?

500
An air mass that is wet and forms over water.
What is a maritime air mass?
500

Lifting of an air mass that occurs when an air mass is forced from high to low elevation by the terrain, such as a mountain.

What is an orographic lifting?
