BLAIN, Gabriel Constantino. Climate trends and variations related to total annual precipitation series of the State of São Paulo, Brazil. Bragantia [online]. 2010, vol.69, n.3, pp.765-770. ISSN 0006-8705.

The aim of the work was to detect trends and climate variations in eight annual precipitation series of the State of São Paulo, Brazil. The investigations was carried out under parametric and non parametric methods in order to obtain a better balance between probability type I and type II errors. Jundiaí and Pindorama presented significant increasing trends in the annual precipitation amounts. In the series of Monte Alegre do Sul those increasing trends had a lower degree of significance. No significant climate change was detected in the series of Campinas, Cordeirópolis, Ribeirão Preto and, Mococa. A decreased trend was observed in the annual precipitation series of Ubatuba.

Keywords : Climate change; parametric; non parametric.
