The present study has as objective to analyze frequencies of Thunderstorm that occurred in the province of Luanda (1998 to 2015), A thermodynamic study of an intense event, to evaluate the operation of the thermodynamic method. This method was based on the vertical profiles, predicted 48 hours in advance, indices of instability and trajectories of the HYSPLIT model for forecasting. Topographic influence was assessed by the evaluation of latent and potential instability (IP and IL) for intense case. The following data were used: (1) TRMM; (2) ECMWF (3) NCEP (4) CPTEC; (5) HYSPLIT. There were 238 cases of thunderstorms, with maximum occurrence in 1999 and 2011, in April (145 cases). In the synoptic analysis it was observed: A) jet stream, b) Medium crest c) cyclonic circulation at low levels. The SST presented values around 28 ° C Strong cold advection (−4K / day 6h) before the event was observed and warm advection weak (4K / day) at the instant of thunderstorm. The simulated profile showed strong instability (CAPE + = 1587, L = −7). The predicted profile was satisfactory up to 36h in advance. All these factors influence the formation of thunderstorms for the region.
