 This study investigates the diurnal characteristics and driving mechanisms of surface urban heat islands, suiz, across different local climate zones, LCCs, and time scales, and identify six prevalent diurnal Suhii patterns with distinct features among built LCC types. The study also explores the individual and interactive impacts of ten morphological, socio-economic, and meteorological factors on the multi-temporal spatial differentiations of Suhii's, finding that enhanced vegetation index, EVI, and gross domestic product, GDP, have the top two individual effects for daytime spatial differentiations of Suhii's, while air temperature, TEM, has the largest explanatory power for nighttime differentiations of Suhii's. The study categorizes all factor interactions as two-factor or nonlinear enhancements, with the strongest interaction being EVI Intersection GDP during the day and TEM Intersection EVI at night. Overall, this study contributes to an improved interpretation of the diurnal continuous dynamics of local Suhii's in response to various environmental conditions.
