Climate Change in Urban Areas: A Case Study of Mysuru City

Abstract

In climate change research studies, trend analysis has played a remarkable role for almost the past 3 decades. The study aims to find out the variations in climate parameters for Mysuru City. The climate variables were examined for annual and seasonal trends for Mysuru City for the period 1980-2020. To determine the increasing or decreasing trend in climate data along with their statistical significance, both parametric test (linear regression) and non-parametric tests (Mann-Kendall and Sen's method) were used. In the current study, the statistically significant increasing trends were detected in annual, winter, and monsoon maximum temperature series and annual and monsoon minimum temperature series. Besides tmax and tmin during summer and tmin in winter does not show any discernible trend. The annual and summer rainfall and relative humidity during summer show a significant increasing trend.
