Diabatic processes contribution to the november 2001 storm

Abstract

Between the 9th-15th of November 2001 a very deep cyclogenesis event occurred in the Western Mediterranean basin. The quantious and dramatic damages both in material and human loses and the recorded values of fall in pressure, heavy rain and wind were so important that it can be qualified as the most important and violent meteorological event for the last decades. The complexity of the meteorological situation was big enough to have all of the ingredients for a very well developed baroclinic cyclone in the first stage and a hurricane-like storm at the second part of the event. In this paper the role of the latent heat release from precipitation and both the sensible and latent heat fluxes in the generation and development of the cyclone is investigated.
