400
When a mT air mass precedes a cold front what can be expected?
What is a line of thunder storms
400
Describe the weather of a stationary front and some dangers of this frontal system.
What is Like a warm front, but it lasts longer. Dangers are flooding and landslides.
500
What is unique about a continental arctic air mass?
What is it is a very cold, dry air mass that can only be experienced during the winter.
500
If a cP air mass behind a cold front is moving through Pennsylvania which city is most likely to be affected first, Pittsburgh or Harrisburg? Explain why you chose this city.
What is Pittsburgh because air masses usually move from West to East in the Prevailing Westerlies.
500
What is likely to happen to an air mass if it moves quickly away from its sources region? How does that differ if it moves slowly?
What is the air mass keeps the characteristics of the source region when it moves quickly. This can create severe weather. When it moves more slowly it can adapt to the surrounding weather conditions.

How do weather conditions differ between a surface which is warmer than an air mass vs. when the surface is colder than an air mass?
What is warmer surface: cumulonimbus clouds, storms
colder surface: fog, nimbostratus clouds
