Investigation of Climate Extremes in Jabalpur District of Madhya Pradesh: Trends and Future Implications

Abstract

Climate change is a long-term change in hydro-meteorological conditions in a particular geographical region. In the present study, spatio-temporal long-term change in rainfall during 1961–2020 was analyzed using IMD 0.25°×0.25° resolution gridded dataset in the Jabalpur district. The non-parametric Mann–Kendall trend test and Sen’s slope estimator was applied to determine the trend and its magnitude, respectively in the precipitation time series. Extreme indices were employed to understand the risks and vulnerabilities associated with extreme weather events in the district. Mann-Kendall trend test showed an insignificant trend at 95% confidence interval with Sen’s slope value of -2.98 to 0.73 mm/year. CLIMPACT tool was used to study extreme indices and it revealed that, in the district, CDD, CWD, R10, R20, and RX5 were decreasing, whereas RX1 and SDII were found increasing. The study’s outcomes provide valuable inferences for future water resource planning and management in central India, particularly in Jabalpur district.
