Abstract Heatwave preconditioned‐heavy rainfall (HW_HR), a preconditioned compound event, can cause more damage than single heatwave or rainstorm. Both heatwaves and rainstorms be exacerbated by the presence of cities, but response their compounding to urbanization remains unclear especially at hourly scale. Here, we investigate spatial temporal responses HW_HR typical urban agglomeration, Pearl River Delta, using observations scenario‐based numerical simulations. Compared rural areas, show that in areas has higher probability occurrence mean intensity, its diurnal cycle frequency is narrower, peaking afternoon. The intensity effects most significant, with urbanization‐induced increase being five times non‐heatwave (noHW_HR). Our simulations support suggest changes are intense spatially heterogeneous relatively weak continuous noHW_HR. also preconditioning not only amplifies key variables alter atmospheric conditions provides pre‐storm unstable environment for urban‐induced warm‐dry surface trigger enhance convection. sub‐daily suggests preconditioning‐induced thermodynamic gradually decrease, whereas dynamic as event approaches. study highlights importance understanding on events, providing new insights into role preconditions water cycle.

Asymmetric Impacts of Urbanization on Extreme Hourly Precipitation Across the Yangtze River Delta Urban Agglomeration During 1978–2012

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.
