Topographic Vorticity-Mode Mesoscale-β (TVM) Model. Part II: Evaluation

Abstract

The new topographic vorticity-mode mesoscale-? (TVM) model, whose formulation is described in Part I of this paper, was used to simulate data from the June 1983 Sixth European Remote Sensing Campaign on Air Pollution at Fos, France. The campaign investigated interactions between mesoscale sea-breeze, lake-breeze, and complex topographic flow regimes, and thus constituted an interesting coastal complex-terrain test for the TVM vorticity-mode formulation. The vorticity-mode model reproduced qualitative and quantitative features of the temporal and spatial variations of observed mesoscale sea, lake, and topographic flows. For example, the model reproduced the main features of observed sea, land, lake, katabatic, and upslope flows.
