Rainfall variability has a substantial impact on water supplies, agricultural output, and, as a result, the economy. It
examines the historical spatiotemporal variability and trend of rainfall on Jharkhand's annual and seasonal time series state
over a 60-year period (1954–2013). The goal of this study was to find trends in long and short-term changes in rainfall amounts
in the Jharkhand region at various spatial scales. With the help of the wavelet technique, we were able to determine the
periodicity of rainfall over time and identify active and break days in the monsoon season.
