Chapter 9: Air Masses and Fronts 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.

Chapter 15: Great Plains Blizzards - ess.uci.edu

issues a blizzard warming when winds are expected to exceed 35 mph (30 knots), and falling or blowing snow will reduce visibility to less than a quarter of a mile for at least three hours. Although cold air is a key component of all blizzards, we do not use specific temperature criteria to define a blizzard.
