Abstract

A subject that has aroused considerable interest in hydrometeorology and hydrology is the establishment of standards Rainstorm focusing on the positioning of the peaks over the duration of the events. We used rainfall data obtained in PCD located in the city of Barreiros in Meso coast of the state of Pernambuco, the period from 01/06/2000 (date of installation of PCD) to 31/12/2010. The methodology identified, besides the already known and referenced standards Advanced, Intermediate and Retarded, the following: Undefined and Multipico. Moreover, through the confrontation of heavy rainfall events identified with the stationary satellite images, the standards set were related to meteorological factors responsible and determinants thereof, giving bigger and better elements for aggregation of advantages in the provision of mitigation measures effects of weather forecasts and conditions within the modern view of weather. Therefore, the aim of this study was to indicate a form of rational presentation and unpublished patterns of heavy rainfall, providing subsidies to redirect the studies, with equanimity, and in accordance with the objectives which they propose, and additionally relate the patterns to weather systems that originate.
