Mann–Kendall trend test and Sen’s slope estimator method were used to find out significant changes in extreme climate indices for daily temperature precipitation Cherrapunji over the period from 1979 2020. In this study, 21 temperature-based calculated using RClimDex v 1.9-3, among which six derived number of days above nn mm rainfall (Rnn) according India Meteorological Department (IMD) convention rest 15, accordance with Expert Team on Climate Change Detection Indices (ETCCDI). It was observed that, all indices, consecutive dry (CDD), summer (SU25) very light (VLR) increased significantly 0.54, 1.58 0.14 days/yr, respectively, while only wet (CWD) decreased 0.36 days/yr.

For minimum temperature, almost no change or a observed, except positive February November monthly (TNN) only. The analysis revealed that some explain climatic conditions have shown statistically 42 years if continues, then will be under threat when it comes change.
