Parametric and non-parametric trend analysis of precipitation for Malkangiri

The present study is mainly concerned with the changing trend of rainfall in a district of Odisha. We have given an effort to analyse one of the most important climatic variable, i.e., precipitation, for analysing the rainfall trend in the area. Daily rainfall data of 102 years from 1901 to 2002 has been processed in the study to find out the monthly variability of rainfall for which the Mann-Kendall (MK) test has been used together with the Sen‟s Slope Estimator for the determination of trend and slope magnitude. A monthly precipitation trend has been identified here to achieve the objective, which has been shown with 102 years of data. There are rising rates of precipitation in some months and a decreasing trend in some other months obtained by these statistical tests suggesting overall insignificant changes in the area. | Parametric and non-parametric trend analysis of precipitation for Malkangiri
