The rainfall regime in the Northeast region of Brazil has an irregularity associated with some physical and atmospheric factors that provides a feature specific to it. There are several ways to analyze the rainfall characteristics of a region; one way is statistically analyze the rainfall index to be able to identify the profile of the region. This work presents a statistical approach between the Brazilian northeast, the city of Fortaleza and the TRMM project of NASA is to evaluate and improve the observation of precipitation in the tropics around the globe. This analysis is based on the 3B42 product, from January 1998 to 2015, with an interval of time of 3 in 3 hours and a resolution of 0.25 °. The results are quite satisfactory in view of the fact that the satellite does not collect data in situ, watching a concentrated rain profile in the morning and in the first six months of the year.
