Heat waves in Florida and their future from high‐resolution regional climate model integrations
Abstract This study examines the simulation of the heatwave events over Florida from the integration of two regional climate models (RCMs) at comparatively high resolution (at 10 km grid spacing) for two decades of the current climate (1986–2005) followed by their projection in the mid‐21st century...
