Abstract


This study investigates the variability and trends in rainfall and temperature in Hyderabad over 42 years from 1981 to 2022. The research uses non-parametric tests and statistical tools to analyze meteorological data to understand regional climatic changes. The findings reveal significant seasonal variations in rainfall, with the highest variability observed during the pre-monsoon, post-monsoon, and winter seasons. The study also highlights a consistent increase in maximum temperatures and a slight increase in minimum temperatures. Evapotranspiration (ETo) data analysis indicates considerable monthly variability, reflecting Hyderabad’s diverse climatic conditions. Notably, the study identifies a declining trend in seasonal rainfall during the JJAS season and significant variability in ETo across different months. These results underscore the importance of continuous monitoring and adaptive strategies to manage water resources and mitigate the impacts of climate change.
