Caracteriza??o estatística de oito séries de precipita??o pluvial máxima diária da secretaria de agricultura e abastecimento do Estado de S?o Paulo

摘要

The aim of the work was to characterize the series of maximum daily rainfall value, observed during each year (Preabs) on the State of S?o Paulo, Brazil. The characterization was carried out by using different probabilities density functions. The Kolmogorov-Smirnov test, the percentiles-percentiles graphics and, the quantil-quantil graphics, indicate that the observed data converges to the general extreme value distribution (GEV) in the locations of Campinas-SP, Cordeirópolis-SP, Mococa-SP, Monte Alegre do Sul-SP, Ribeir?o Preto-SP and Ubatuba-SP. Increasing trends were detected only for the Pindorama-SP series. The Fourier and the wavelets analysis indicate no significant periodicities in all analyzed series.
