Continental Arctic or Continental Polar.


Air masses that form over land are Continental, as opposed to Maritime. Frigid air masses from high arctic latitudes are called Arctic, and middle latitudes are Polar, as opposed to and Tropical. Air masses that form far north in Canada are Continental Arctic and ones that form in Southern Canada are Continental Polar. Generally speaking when you say "frigid" we normally think Continental Arctic.
