Abstract:

In this study, three different statistical downscale method namely delta method (DM), quantile mapping method (QMM) and empirical quantile mapping method (EQMM) are compare to downscale precipitation for Upper Shivnath basin. Model for Interdisciplinary Research on Climate 5 (MIRCO5) simulation model is used for future Representative Concentration Pathways (RCP) scenarios (RCP4.5) to project decadal changes in precipitationacross eighteen selected stations of Upper Shivnath basin. Three decades are selected for future prediction viz. 2020–2039, 2040–2059, 2060–2079 and 2080-2099 and are compared decadal variabilities with period 1990–2013. Delta method is accurately downscale precipitation from Model for Interdisciplinary Research on Climate (MIRCO5) model for future Representative Concentration Pathways (RCP) scenarios (RCP4.5) to project decadal changes in precipitationacross eighteen selected stations of Upper Shivnath basin as compere to quantile mapping and empirical quantile mapping methods. The downscale precipitation of Upper Shivnath basin from Interdisciplinary Research on Climate (MIRCO5) model for 2020-2039, 2040-2059, 2060-2079 and 2080-2099 scenarios are observed decrease trend in future.
