Dryspell Analysis Using Gridded Rainfall Data For Telangana

The study analyzes the spatial and temporal patterns of dry spells in Telangana using gridded rainfall data spanning 1961 to 2015.The analysis employs the Mann-Kendall test to identify trends in dry spell occurrences and their lengths.Results indicate considerable spatial variability, with southwestern and southern districts experiencing the longest and most severe dry spells, while northeastern and eastern districts encounter shorter durations.Although most locations exhibit a non-signi icant trend towards reduced dry spell lengths, higher elevation areas such as Vikarabad and Rangareddy show a signi icant decrease, highlighting the critical role of topography in in lucing dry spell patterns.The study underscores the challenges including limitations of using gridded rainfall data, topographical complexities, and variability in de ining dry spell thresholds, all of which affect the accuracy of results.Despite the challenges the research makes key contributions by providing a detailed regional analysis of dry spells and identifying critical zones of vulnerability.The study also highlights the critical need for regional-scale analysis to accurately assess local impacts and develop adaptive strategies tailored to the speci ic climatic and geographic conditions of different districts.Future research should incorporate recent data, consider climate change impacts, and integrate socio-economic factors to provide a holistic understanding of dry spell implications in Telangana.
