Abstract Urbanization has become a prominent anthropogenic activity globally, resulting in the substantial modification of temperature and rainfall around urban areas. Studies also indicate that exhibits an asymmetrical shift from light to extreme rainfall, causing both floods droughts over different parts globe. However, what extent urbanization influences changes drought remains understudied. Accordingly, we provided investigation effects on events statistical model‐based perspectives. Results showed generally increased heavy decreased rainy season five agglomerations (i.e., Yangtze River Delta [YRD], Middle Region [MRYR], Chengdu‐Chongqing, Guizhou, Yunnan) Basin during 1981–2020. Specifically, contributed 42.7% 30.8% increases MRYR YRD while 30.6% contribution decrease rainfall. Interestingly, results suggested regions were more prone due urbanization. Nevertheless, found some variabilities across areas interactions with complex terrains climate patterns. Further simulations using Weather Research Forecasting model confirmed our findings helped understand potential underlying mechanism. The current research is expected provide scientific knowledge for better planning preparedness urbanization‐induced hazards.

Urbanization Enhances Shorter‐Duration Precipitation Intensity in the Yangtze River Delta Region

Journal of Geophysical Research Atmospheres, Год журнала: 2025, Номер 130(8)

Abstract Understanding the response of extreme precipitation events under urbanization conditions is vital for mitigating risk urban flooding. Nevertheless, previous studies assessing impact on often neglected role natural climate variations. To fill this gap, study aims to investigate how varying durations responds urbanization, accounting We classified agglomeration Yangtze River Delta (YRD) in East China into nine distinct groups based seasonal patterns, utilizing structural self‐organizing maps (SOM), and explored relationship between with Geographical Detector Model. The results revealed substantial fluctuations within YRD, showing significant spatial variability underscoring importance considering variations studies. After variations, our findings unveiled a notable urbanization‐induced effect, particularly prominent during summer autumn. Additionally, urbanization's influence demonstrated time‐scaling shorter‐duration exhibiting stronger correlation urbanization. Furthermore, interaction elevation surpassed individual factors, intensifying as event duration decreased, especially less than 3 days, indicating more complex mechanism their precipitation. This research enhance understanding shapes patterns. These are crucial planning adaptation strategies address risks associated heavy areas.
