Abstract
Two commonly used methods for calculating the sensible heat from the Monin-Obukhov similarity hypothesis are evaluated. Temperature and horizontal wind speed profiles taken over a melting mid-latitude valley glacier are used as the evaluating data set. An iterative approach (Berkowicz and Prahm, 1982) used within the boundaries of the profile produced satisfactory results for the sensible heat flux. An approach which uses a log-linear model and extrapolates beyond the data range (Webb, 1970) was also tried. It failed to produce results which could stay within plausible bounds for a sensible heat flux over a melting glacier. Failure of the latter method is postulated to be due to a greater sensitivity in this approach to zero plane displacement errors associated with referencing the profile heights.
