Continental Arctic (cA)
Air Masses
• Continental
Arctic (cA) air represents extremely cold
and dry conditions as, due to its temperature, it
contains very little water vapor.
• The
boundary between cA and cP air is the shallow (~1-2 km) arctic
front.
•cA
air masses can extend as far southward as the Canadian-United
State.
