Abstract Understanding sub‐daily precipitation extremes (SPEs) can provide scientific insights for taking effective measures to mitigate climate risks. Leveraging gauge observations at hourly in 2,312 meteorological stations and extreme indices (ESPIs), we investigate the changes of SPEs flooding season 1971–2022 China. On country scale, occurrences intensity have significantly increased even accelerated since 21st century, suggesting increases 2010s by 15%–38% compared with that 1970s. The SPE risks 20‐year 50‐year return‐period 2–4 8–20 times 2001–2022 1971–2000, respectively. Over 80% are found positive trends all ESPIs. regional seven sub‐regions experienced significant ESPIs larger magnitudes East enlarged 500‐hPa geopotential height, 700‐hPa pseudoequivalent potential temperature, specific humidity, saturated vapor pressure urbanization ratio may be bonded more SPEs.

ABSTRACT North China faces increasing risks from extreme precipitation under climate change, yet projections integrating socio‐economic dynamics with high‐resolution models remain limited. Leveraging the latest version of NEX‐GDDP‐CMIP6 (NASA Earth Exchange Global Daily Downscaled Projections) NASA (National Aeronautics and Space Administration) CMIP6 (Coupled Model Intercomparison Project Phase 6) datasets across SSP1‐2.6, SSP2‐4.5 SSP5‐8.5 scenarios, this study quantifies future impacts on urban populations cropland in two critical periods: 2031–2050 (mid‐century) 2081–2100 (end‐century). Through Multivariable Integrated Evaluation Tool (MVIETool), we demonstrate that reduces regional biases by 79% compared to (from +133.16 mm/day −27.00 mm/day), despite persistent uncertainties intensity indices. Projections reveal a pronounced intensification precipitation, R99p (extremely wet day precipitation) 127%–131% CDD (consecutive dry days) decreasing 12%–17% SSP5‐8.5, signalling transition toward wetter conditions. Exposure analyses indicate 38.24 million citizens (26.32% population) 49,900 km 2 (5.87% area) may face record‐breaking events end century primarily concentrated coastal megacities Plain. These findings underscore urgency scenario‐specific adaptation strategies, including ‘sponge city’ retrofitting high‐exposure zones precision agriculture tailored regime shifts. Our integrated framework advances risk assessments reconciling dynamical downscaling limitations SSP‐driven uncertainties.
