Abstract

An objective synoptic climatology of daily 500mb pressure patterns for the International Hydrologlcal Decade (1965-1974) for southwestern Canada is presented. The climatological characteristics of the synoptic types are examined in terms of the natural glacier seasons of Sentinel Glacier, British Columbia. Although the number of years available for analysis is limited, a significant statistical relationship between the mass balance of Sentinel Glacier and the small-scale synoptic types is present. Glacier accumulation appears to be controlled mainly by the number of synoptic types associated with heavy precipitation that occur during the fall, winter, and spring. Summer melt is largely a function of the frequency of those synoptic-scale patterns bringing high temperatures and clear skies to the region. © 1984 Taylor & Francis Group All rights reserved.
