“…Recent studies have also highlighted the effects that sea surface temperature (SST) inhomogeneities can produce on mesoscale atmospheric systems in midlatitudes [12][13][14][15][16][17]. In the past decades, among the most severe and destructive events that affected the central part of the Mediterranean basin, we recall the ones which occurred in October 1970, September 1992, September 1993, and more recently, September 2002, October 2010, October and November 2011, and October 2014 [18][19][20][21][22].…”

In late summer and autumn Mediterranean coastal regions are quite regularly affected by small-scale, flood-producing convective systems. The complexity of mesoscale triggering mechanisms, related to low-level temperature gradients, moisture convergence, and topographic effects contributes to limit the predictability of such phenomena. In the present work, a severe convection episode associated to a flash flood occurred in Cannes (southern France) in October 2015, is investigated by means of numerical simulations with a state-of-the-art nonhydrostatic mesoscale model. In the modelling configuration operational at the University of Genoa precipitation maxima were underestimated and misplaced. The impact of model resolution as well as initial and boundary conditions on the quantitative precipitation forecasts is analyzed and discussed. In particular, the effect of ingesting a high-resolution satellite-derived sea surface temperature field is proven to be beneficial in terms of precipitation intensity and localization, especially when also associated with the most accurate lateral boundary conditions.
