Chinook

Jocelyn from somewhere in Canada:

"Like a warm wind, the word chinook is defined as a moist warm wind blowing from the sea in coastal regions of the Pacific Northwest; a warm dry wind that decends from the eastern slopes of the Rocky Mountains causing a rapid rise in temperature.
During our cold Canadian winters, a welcome arrival is the chinook, ushering in those warm winds and temperatures albeit briefly, to shake us from our winter doldrums. Raise a glass and shout "Chinook" and feel the warmth.
"
