Trend analyses of regional time series of temperatures and rainfall of the Tapi basin

Climate change information at the scale of basin is vital for planning, development and use water. The Tapi climatically responsive. Hydrological response a based mainly on rainfall temperature. Variations in climate regional scales impacts fundamental features our life. Thus, present work, trend analyses time series (1971-2004) minimum, mean, maximum temperatures rainfallis performed monthly, annual seasonal basin. Correlogram utilized evaluation dependence data. Mann-Kendall test with block bootstrapping are applied significance. Sen’s slope magnitude. Sequential assessment beginning end trend. Statistically significant positive trends detected winter Tmean their years 1974 1972, respectively.
