Very cool
or
Named winds

I googled that as well, a very cool wind.
Calgary has a similar phenomenon called chinook winds.
The links said Taku winds are cold and occur in the winter, chinook winds are warm winter winds.
You can see a chinook coming, another phenomenon called the chinook arch.
The warm winds push under the cold air and slide down the eastern slopes of the Rockies into Calgary.
Temperatures can rise as 30 or 40 degrees celsius in a matter of hours.
Leaving home in the morning it could be minus twenty, coming home in the afternoon, plus fifteen.

In addition to the chinook winds warming the city Calgary gets a similar but opposite situation.
The warm air can come off the mountains and cover the cold air below.
Calgary sit in a natural bowl caused by the meeting of the Bow and Elbow Rivers.
The bowl fills up with the fumes from the city, it fills quickly.
This creates spikes Calgary's air quality, it becomes very very bad.
From a high vantage you can actually see the layer of pollution trapped in the city below.
This picture is taken from a ridge on the SW corner of the city called Signal Ridge.
You can see the yellow soup that forms from the trapped pollutants.
