Abstract
This study aims to identify the rate of convective and stratiform rain in the state of Pernambuco (Brazil), with data collected by the satellite TRMM. For the research, 12 points in different cities were chosen to work with the data of the algorithm 3A25, with a spatial resolution of 0,5°x0,5° from January 1st, 1998 to June 30th, 2011. After the analysis of the rates, variations of the rates according with the spatial localization of the points were identified. The higher convective rain rate was in Cabo de Santo Agostinho (3,32) and the lower rate was situated in Santa Cruz (2,22). Regarding stratiforms rain, the rates varied according to their special localization. The points which presented the highest rates were the closest to the coastline – Cabo de Santo Agostinho (1,19); Bezerros (0,92); Belo Jardim (0,83). The points that showed the lowest averages are the ones far from the littoral - Parnamirim (0,74); Santa Filomena (0,69); Santa Cruz (0,83).
