B. Denby et W. Greuell, The use of bulk and profile methods for determining surface heat fluxes inthe presence of glacier winds, J GLACIOL, 46(154), 2000, pp. 445-452
A one-dimensional second-order closure model and in situ observations on a
melting glacier surface are used to investigate the suitability of bulk and
profile methods for determining turbulent fluxes in the presence of the ka
tabatic wind-speed maximum associated with glacier winds. The results show
that profile methods severely underestimate turbulent fluxes when a wind-sp
eed maximum is present. The bulk method, on the other hand, only slightly o
verestimates the turbulent heat flux in the entire region below the wind-sp
eed maximum and is thus much more appropriate for use on sloping glacier su
rfaces where katabatic winds dominate and wind-speed maxima are just a few
meters above the surface.
