Evidence of long lee waves in Southern Alberta

Abstract

A brief review of past studies of the of the order of 50—100 km or longer, chinook and a summary of some recent although resonance may be present satellite and visual observations of the in some cases. Both satellite and visual chinook arch cloud are presented as observations indicate the frequent ocevidence of the occurence of long currence of the wave during the colder gravity wave phenomena in the lee of period of the year. Taken together, the Rockies of Southern Alberta and these data imply that the wave pheno‐Northern Montana. A quasi‐stationary menon is potentially important in cloud band that extends several de‐ terms of local surface weather and grees of latitude along the lee of the vertical momentum transport and that mountains appears to be associated it should be subjected to more detailed with a single long wave with a length theoretical and observational studies.
