100
An air mass that is very dry and extremely cold that forms up near the north pole before it moves south into our area.
What is Continental Arctic?
100
A front that forms as a cold air mass pushes a warm air mass.
What is a Cold Front?
100
This type of precipitation forms when warm moisture in clouds is cooled and condensed.
What is Rain?
100
This can form during a very violent thunderstorm as a result of rotating updrafts and downdrafts.
What is a Tornado?
100
Large pressure difference that occur over very short distances will produce this.
What are Strong Winds?
200
An air mass that is very warm and has the ability to carry a large amount of moisture because it forms over the ocean.
What is Maritime Tropical?
200
A front that forms as a warm air mass pushes a cold air mass.
What is warm front?
200
This type of precipitation forms a result of freezing temperature throughout all layers of the atmosphere
What is Snow?
200
This storm is fed by very warm ocean water, and it is capable of producing sustained winds from 75 m.p.h. to 150 m.p.h. over a large area.
What is a hurricane?
200
This type of pressure system produces very nice weather as it spins clockwise across the United States.
What is a High Pressure System?
300
An air mass that forms over a desert might be refered to as this.
What is Continental Tropical?
300
A front that is that boundary between warm and cold air masses, which is stuck in place because of little upper level movement.
What is a Stationary Front?
300
In a violent thunderstorm rain drops that are picked up by updrafts and frozen as they are thrown through the clouds eventually falls as this type of preciptation.
What is Hail?
300
A violent winter storm that can produce very cold temperatures, significant snowfall and very strong winds.
What is a Blizzard?
300
These pressure system spins counter-clockwise as winds blow inward and wrap around the center.
What is a Low Pressure System?
400
A cold air mass that forms over pacific ocean south of Alaska and then moves into the northwestern United States would be called.
What is Maritime Polar?
400
This front forms as a result of a cold air mass being pushed slowly by a warm air mass, and then a strong cold air mass quickly sweeps both air masses together.
What is an Occluded Front?
400
This precipitation is partially frozen rain drops that refreeze in the lower levels of the atmosphere during the winter.
What is Sleet?
400
A coastal storm of both rain and snowfall that travels up the Atlantic coast pulling in moisture and gives Pennsylvania strong winds from the North and East.
What is a Nor'easter?
400
A hurricane is a powerful tropical storm with very strong winds. The pressure reading in the eye of the storm would be.
What is very Low?
500
This type of air mass is the driving force behind an occluded front.
What is Continetal Polar or Continental Arctic?
500
This front forms between air masses of similar temperature, but very different amounts of moisture.
What is a Dry Line or a Dew Point front?
500
This precipitation begins as snow but falls very quickly due to warmth in the lower atmosphere, however when it strike that frozen ground it freezes on contact.
What is Freezing Rain?
500
A winter event that produces very cold temperatures and very heavy snowfall of a period of several days, but does not have strong winds.
What is a Snowstorm or Winterstorm?
500
Lines of equal pressure that surround pressure systems are called.
What are Isobars?
