Abstract
Abstract The heavy rain event of 30 January to 4 February 1993 in the Segura Basin in SE Iberia is investigated The study emphasizes the atmospheric processes that led to thunderstorm development The meteorological scenario has been separated into preconvective and convective periods and into largescale and subsynoptic settings The warm moist air flow from the Mediterranean Sea channelled by a highoverlow blocking pattern with a cold front over southeastern Iberia appears to be the main reason that helped trigger a severe weather occurrence The study of the mesoscale environment parameters showed an enhanced conditional unstability through a deep troposphere layer with a moderate to strong vertical wind shear that promoted conditions to allow organization of longlived convective structures
