Abstract
The event of intense precipitation causing flood and heavy damages over Piedmont in November 1994 has been simulated by means of the hydrostatic limited area model, the Eta model version 1993, at an horizontal resolution of about 25 km and 17 levels in the vertical.We analyse total and convective precipitation fields cumulated over a 6 hour period obtained from the Eta model, in order to select some areas and time intervals, in which the convective component of precipitation is prevailing. We analyse the behaviour of the convective adjustament process by comparing vertical cross sections and profiles obtained from Eta model against those obtained from ECMWF initialised analysis.
