Abstract
A simplified fluid-dynamical scheme is formulated, based on the inviscid hydrostatic equations for the moist atmosphere, in order to study the rainfall distribution over a terrain with complex orography. Assuming a slow evolution of the main meteorological forcing, such as in the presence of frontal circulation, a small-scale diagnostic model is delineated, where the input is given from synoptic-scale analysis and/or predictions. A preliminary semigeostrophic version of the model is tested on a real case study over the Apennine chain (Central Italy) and the results are briefly discussed.File in questo prodotto:
