Some Observations of Alaskan Glacier Winds in Midsummer

Abstract

Discusses 21 June-12 July observations at Castner Glacier in the Alaska Range and 16 July-11 Aug 1967 at Worthington Glacier in the Chugach Range. The purpose was to study the frequency and diurnal variation of glacier winds and differences due to location and exposure. In both cases max windspeed occurs slightly before sunrise and in the mid-afternoon. In the absence of a daytime glacier wind at Castner, a regular night downslope circulation is often observed.
