Abstract

ABSTRACT. The effect of change in orientation and surface roughness of terrain on the daytime up slope flow is investigated using a 2-dimensional mesoscale model. A realistic orography profile of western ghat is chosen for the purpose. Twelve hour of integrations are performed starting from sunrise. The numerical simulation have shown that the intensity of up slope flows remained practically unaffected by change of orientation of terrain. However, increase in roughness length decreases the intensity of developed flows. For comparison purposes, the results of previous investigators are verified with a change in slope angles.
