<![CDATA[Climate change is increasingly driving extreme weather events, yet its regional impacts remain complex. This study employs the RegCM5 model, driven by ERA5 reanalysis data, to simulate high-resolution (5 km) climate dynamics in Surabaya, Indonesia from December 2018 to November 2023. Validated against gridded observational datasets and analyzed via Earth's energy balance, the results reveal a steady rise in both top-of-atmosphere and surface energy imbalances, corresponding with record-breaking increases in maximum and minimum temperatures by approximately 1.5°C and 1°C from 2020 to 2023. While monthly precipitation patterns were inconsistent, daily observations indicate a significant increase in high-intensity precipitation events. These findings offer critical insights into evolving regional climate impacts and inform local adaptation and mitigation strategies.]]>
