Significant progress has been made in understanding how extreme precipitation responds to climate warming across various time scales. However, the impact of urbanization on these events remains unclear. This study aims thoroughly examine effects hourly (EHP) and its spatial heterogeneity based dynamic station classification methods EHP indices using high-resolution records Yangtze River Delta (YRD) urban agglomeration. We also explore contributed changes associated uncertainties. The results indicate an overall increase all YRD, with significant increases being more pronounced areas. Furthermore, correlate positively urbanization, showing greater at higher levels urbanization. While cannot be overlooked, contribution appears relatively limited, contributions less than 50%. are predominantly positive, noticeable for different sub-regions temporal variations during stages or Moreover, influenced by urban–rural methods, especially regarding their contributions.
