In recent days observed extreme variations in the climate and weather events are increasingly being recognized as key aspects of climate change. ln this study we assessed the spatial-temporal variability of minimum and maximum temperature over the Kalaburgi district of Karnataka, India for the period 1981-2018, using gridded data with 0.5-degree resolution obtained from National Aeronautics and Space Administration prediction of worldwide energy resource (NASA POWER) project. Trend detection and quantification in the temperature evaluated using the non-parametric Mann-Kendall (MK) test and Sen’s slope estimator. The overall average of minimum and maximum temperature data and Sen,s estimate showed the increasing trend in series for the last 38 years. The highest average minimum temperature observed is densly distributed over the Jewargi with a range of 24.74 0C to 26.68 0C and all other places found sparsely distributed with range 19.98 0C to 23.50 0C. ln the overall, the spatial distribution analysis results observed the densely distribution of maximum temperature in AIand, Afzalpur, Jewargi and part of Kalaburgi with range of 32.88 0C to 33.99 0C. The average maximum temperature exhibited the increasing trend linearly and Sen's slope also estimated increasing trend in the study area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
