AbstractEstatísticas de ordem são usadas para definir as principais características da estação chuvosa em São Paulo, que incluem seu início, fim e duração, além da distribuição das quantidades de chuva e riscos de veranicos. As análises foram feitas a partir dos registros de precipitação diária em Piracicaba, localizada no interior o Estado, no período de 1917 a 2014. As datas de início obtidas foram: 20 de setembro para o início potencial e 12 de outubro para o efetivo, que é o início das chuvas condicional a não ocorrência de um veranico consecutivo. O fim da estação chuvosa foi definido como sendo no dia 10 de março e sua duração efetiva mediana foi de 152 dias. Constatou-se uma significativa dependência linear inversa (r=-0,74) entre o início potencial e a duração. As precipitações esperadas por pentadas nos diversos níveis de probabilidade foram obtidas através de ajustes de distribuições gama. Também são apresentados resultados sobre o risco de veranicos de 5 a 30 dias nos 30 dias seguintes. Finalmente, são computadas as frequências percentuais de eventos secos e chuvosos nas suas diferentes intensidades, de leves a extremos, nas escalas de 1 a 12 meses, usando o SPI. Conclue-se que estes resultados tem bastante interesse prático para fins de planejamento e operação de sistemas de recursos hídricos para fins hidro e agrometeorológicos. ABSTRACT: Order statistics were used to define the main features of the rainy season in São Paulo, Brazil, including their start, end, and duration, in addition to the distribution of quantities of rain and risk of dry spells. The analysis was performed from daily rainfall records in Piracicaba, located inside the State, in the period of 1917 to 2014. The obtained start dates were: September 20 for the early potential and October 12 for effective one, which is the start of rains conditional to a non-occurrence of one consecutive dry spell. The end of rains was defined as being the day March 10, and your effective average duration was 152 days. There was a significant inverse linear dependence (r = -0.74) between the start and the duration. Precipitation expected by pentads in the various levels of probability were obtained through adjustments to gamma distributions. Are also presented findings on the risk of 5 to 30 days dry spells in the following 30 days. Finally, the relative frequencies of rainy and dry events in their different intensities from light to extremes, on the scales of 1 to 12 months, are computed using the SPI. It is concluded that these results have great practical interest for design and operation of water resources systems for hydro and agrometeorological purposes.
