Alberta low

A low that originates centered on the eastern slope of the Canadian Rockies in the province of Alberta, Canada.

Formerly, it was thought that such lows actually originated (more or less independently) over this location. It is now recognized that depressions moving inland from the Pacific are the actual parent systems. Alberta lows appear as these systems enhance, or are enhanced by, the dynamic trough that is a typical, almost semipermanent, feature of this region.
