polar air
Cold from north
Polar air is cold air mass originating from high-latitude regions near the poles.
In meteorology, it's distinguished from arctic air (colder, from the Arctic) and tropical air (warmer, from lower latitudes).
When polar air moves south, it brings sharp temperature drops: A polar air mass is expected to sweep through the Midwest this weekend.
