ANALYSIS OF SURFACE TEMPERATURE HEAT AND MOMENTUM FLUXES IN ANKARA

Zafer Aslan, S. Topgu, S. Oney

Abstract


Surface heat fluxes determine the thermic efficiency of the atmospheric boundary layer. Large heat fluxes intensify vertical motions, increase the height of inversion layers and present favourable soaring conditions. In this study, the average sensible heat and momentum fluxes are obtained from observed profiles of the wind and temperature using the similarity relations for the lower part of the atmospheric surface layer in Ankara for the year of 1985. The effect of spatial variations of the sensible surface heat and momentum fluxes is studied for various topographies. These analyses show the principal boundary conditions for weather forecasting, micro- and meso-scale analysis, soaring activities and air pollution models.
