摘要

A comprehensive assessment of spatiotemporal trends in precipitation, maximum temperature (Tmax), and minimum temperature (Tmin) in Odisha’s 30 districts from 1993 to 2024, using multi-method approach that combines the Mann-Kendall (MK) test, Sen’s Slope Estimator, and Innovative Trend Analysis (ITA) with Inverse Distance Weighting (IDW). The research validates substantial regional variation in climate trends. Southern and western districts, such as Koraput, Malkangiri, and Gajapati, show rising precipitation patterns, most likely due to orographic effects and increased monsoon activity, whereas coastal regions like Balasore show large losses, raising concerns about water supply. Tmax shows a major decreasing trend in 14 districts, particularly in coastal and eastern regions, challenging global warming predictions, whereas Tmin shows significant increases in coastal districts such as Jagatsinghpur and Jajpur, indicating night warming and a narrower diurnal temperature range. The ITA identifies both monotonic and non-monotonic trends: higher rainfall in coastal districts and drying trends in western districts such as Bolangir and Nuapada. Such findings demonstrate climatic processes in Odisha with implications for agriculture, water resource management, and disaster preparedness.
