100% Correct Answers
What is an Air Mass? - correct answer✔✔ An Air mass is a large body of air usually 1000 miles or more
across that has similar properties of temp and moisture in the horizontal.
What are the best source regions for air masses? - correct answer✔✔ Large late areas where air can be
stagnant long enough to take on the characteristics of the surface below
What pressure area will the source region occur in? - correct answer✔✔ Area of High Pressure
What factors determine the weather in an air mass? - correct answer✔✔ Moisture, stability and cooling
or heating
What are the different classifications for air masses in terms of Moisture - correct answer✔✔
Continental=Dry and Maritime=Moist
What are the different classifications for air masses in terms of Temperature - correct answer✔✔
Arctic=Cold, Polar=Cool/Cold and Tropical=Warm
What are the Common air masses in Canada? - correct answer✔✔ Continental Arctic (cA in the winter)
Maritime Arctic (mA summer and winter)
Maritime Polar (mP summer and winter)
Maritime Tropical (mT summer)
What are Continental Arctic conditions like? - correct answer✔✔ Cold and dry. Originates north of the
Arctic Circle. During the winter, this air often plunges southward over Canada and the USA. Rarely form
in the summer
, What are Maritime Arctic conditions like? - correct answer✔✔ Cold and Moist. Usually form farther to
the south of Continental Arctic air. Very common during the winter in Canada. During the summer these
air masses bring clear and pleasant weather to the north
What are Maritime Polar conditions like? - correct answer✔✔ Cool and moist. These air masses form
over the northern Atlantic and northern Pacific oceans. They usually bring cloudy damp weather to
Canada. They often influence the Pacific Northwest and Atlantic northeast. Can form at any time
What are Maritime Tropical conditions like? - correct answer✔✔ Warm temp and lots of moisture.
Maritime tropical air masses are most common across eastern Canada and originate over the warm
waters of the southern Atlantic ocean and the gulf of mexico. These air masses are responsible for hot
humid days in the summer
What happens when a cold air mass moves over a warmer surface? - correct answer✔✔ The lower
layers are warmed and may become unstable
What happens when a warm air mass moves over a colder surface? - correct answer✔✔ The lower
layers are cooled and tend to stabilize
What are the characteristics of a Stable air mass? - correct answer✔✔ Poor low level visibility, layer type
cloud, steady precipitation, steady winds which can change markedly with height and smooth flying
conditions
What are the characteristics of a unstable air mass? - correct answer✔✔ Good visibility (except in
precipitation), convective type cloud, showery precipitation, gusty winds and turbulence
What is a Front? - correct answer✔✔ A transition zone between two air masses
What can a Front cause? - correct answer✔✔ Abrupt changes in temperature, wind and humidity
How is the weather that occurs at a front determined? - correct answer✔✔ The stability and moisture
content of the warm air mass
The speed of the front is determined by the cold air mass
