This work presents atmospheric instability conditions associated to the occurrence of Mesoescale Convective System (MCS) in the metropolitan region of Fortaleza – CE, at 06/04/2002. The investigation is based in instability indexes (K, TT, LI) and Convective Available Potential Energy (CAPE). Radiossondes and Radar images were used in the investigation. The data were collected during the Experiment of Microphisics of Clouds (EMfiN!) from 02 to 12/04/2002. Preliminary results show that MCS produced a high rainfall on the metropolitan region of Fortaleza. In addition, the paper shows meteorological diagrams (Skew T, Log P) that identify the presence and conditions of instability associated to these meteorological systems.
