| Summary: | Two aspects of the glacier-climate problem are investigated by linear regression analysis of data from White Glacier (Axel Heiberg Island) and surroundings: (1) the relationship between air temperatures over glaciers and at distant weather stations; (2) the relationship between short-term ablation and air temperature. Parameters in the two models are found to be reasonably consistent for different samples. Averaged parameters for the models are incorporated into a further model to simulate summer ablation on White Glacier for 1960-72 using summer temperatures at distant weather stations as input data. Results are tested by comparison with observed annual net balance data. Main sources of discrepancy are the effects of accumulation. Analysis of data from twelve other glaciers suggests that relationships between mass balance and temperature are reasonably consistent for different glaciers and can be interpreted in terms of results from the White Glacier. |
