You have hear the weather man say “ Another Arctic air mass moving down from Canada…”
Why do we always blame the Canadians for cold weather? The term Arctic Air Mass refers to cold air mass that develops around the Arctic (north pole) and is characterized by being cold from the surface to great height.
In meteorology, an air mass is a volume of air defined by its temperature and water vapor content. Air masses cover many hundreds or thousands of square miles, and adopt the characteristics of the surface below them. They are classified according to latitude and their continental or maritime source regions. Colder air masses are termed polar or arctic, while warmer air masses are deemed tropical. Continental and superior air masses are dry while maritime and monsoon air masses are moist. Weather fronts separate air masses with different density (temperature and/or moisture) characteristics. Once an air mass moves away from its source region, underlying vegetation and water bodies can quickly modify its character. Classification schemes tackle an air mass' characteristics, and well as modification. Source Wikipedia
In the image above the first letter describes its moisture properties, with c used for continental air masses (dry) and m for maritime air masses (moist). The second letter describes the thermal characteristic of its source region: T for Tropical, P for Polar, A for arctic or Antarctic
So really we could instead blame the elves and Santa Claus for the Arctic Air mass since it originates from the North Pole well north of Canada but no one could ever speak poorly of Santa.
If an Arctic Air mass meets a southern flow of warm air the results can be Freezing Rain and Tornados causing trees to fall and wind damage.
