What are warm, cold, stationary, and occluded.
100
This is another name for a cyclone.
What is a low pressure center.
100
This is the scientist that studies and tries to predict weather.
What is a meteorologist.
100
What does a blue H on a weather map represent? What type of weather will it bring?
A high pressure area or anticyclone. It means cool weather without precipitation.
200
This is formed when 2 air masses of different temperatures meet.
What is a front
200
This type of storm is caused by a cold front.
What is a thunderstorm
200
This is another name for a high pressure center.
What is an anticyclone.
200
This is the type of weather that will be found near a low pressure center.
What is cloudy and possible precipitation.
200
What does this symbol mean? *
snow
300
This is the proper name for a warm air mass formed over land.
What is continental tropical.
300
This type of front is formed when a warm air mass slowly pushes a cold air mass out of the way.
What is a warm front.
300
In what direction does air move around a cyclone?
Toward the center and counterclockwise.
300
How will the air temperature change after a cold front moves through an area?
It will be colder.
300
Draw a weather station symbol for 75% cloud cover.
Circle 3/4 filled in.
400
This is the proper name for a cold air mass formed over the ocean.
What is maritime polar.
400
This type of front is formed when 2 cool air masses trap a warm air mass above the earth's surface.
What is an occluded front.
400
In which direction does air move around an anticyclone?
Away from the center and clockwise.
400
This is the type of front that will move through an area the fastest.
What is a cold front.
400
This is the type of information you get from a wind barb.
What is wind direction and wind speed.
500
Explain why warm air masses rise above cold air masses.
Warm air particles are farther apart and therefore warm air is less dense and floats above more dense cold air.
500
This is the type of front that will bring rain for the longest period of time.
What is a stationary front.
500
Which allows fronts to form: cyclones or anticyclones?
cyclones
500
What is the difference between isobars and isotherms?
Isobars measure air pressure Isotherms measure air temperature
500
What are the weather conditions like where isobars are very close together?
Very windy.
