✦ Synopsis
The profile structure of wind speed and temperature in katabatic flow over a melting glacier is analyzed within the log-linear framework. Similarity between windspeed and temperature profiles is indicated but the log-linear model should be restricted to heights within 1.5 m of the ice. Marked deviation from the model occur at greater heights, probably due to the effects of flux divergence. Unlike results from other stable atmospheres, Q decreases with increasing stability. This may arise from the use of the Obukhov length L. When the height H at which the wind speed reaches its maximum value is used instead, (Y does not vary with stability. It has mean values of 4.5 and 4.3 for windspeed and temperature profiles, respectively.
