Evolutions des températures et des précipitations dans le versant sud du bassin de la rivière Paranapanema, Parana, Brésil.

Abstract : The following paper presents an analysis of inter-annual variability of temperature and precipitation at the South of Paranapanema River's hydrographic basin, trying to identify a possible climate variation on the region. Daily data of temperature and precipitation from 1979 to 2010 were submitted to Mann-Kendall and Pettitt's linear regression test. The result shows that spatialtemporal variability is driven by latitude and two different thermal regimen were identified in the region. Linear regression test has identified a rising tendency of temperature, while Mann-Kendall test revealed positive tendencies for annual absolute maximum temperature only for Fernandes Pinheiro station. Analysis of precipitation variability identified higher precipitation means for 1980, 1982, 1983, 1997, 1998 and 2009, which were classified as rainy years according to percentile rank. The years 1984, 1985, 1988, 1999, 2006 e 2008 were dry. Linear regression shows a falling for total annual rainfall, but Mann-Kendall and Pettitt tests demonstrate no variation tendency of annual precipitation in South of Paranapanema River basin.
