While climate change is altering precipitation patterns and snow cover in High Mountain Asia (HMA), our understanding of ROS patterns and their underlying mechanisms remains limited. This study comprehensively analyzed the spatiotemporal distribution, trends, and potential flood risks associated with ROS (snow water equivalent (SWE) ≥ 1 mm and rainfall ≥ 1 mm) and ROS flood (SWE ≥ 10 mm and rainfall ≥ 10 mm) events in HMA using SWE and ERA5-Land rainfall data. Approximately 37.1% of HMAs have had at least one ROS event during hydrological years from 1979 to 2018 and their frequency increased with elevation. The dominant seasons for ROS production were winter at low altitudes, spring at mid-altitudes, and summer at high altitudes. Trend analysis revealed that lower elevations showed a decline in ROS events attributable to reduced SWE; whereas, higher elevations experienced an increase owing to a shift from snowfall to rainfall. ROS<sub>flood</sub> events significantly accelerated snowmelt (1.27-times faster than non-ROS events, respectively). ROS<sub>flood</sub> events, though low-frequent, accounted for 2.52% and 1.55% of the total regional rainfall and snowmelt, respectively, with the main flood risk concentrated in mid-altitude regions around 3.0‒4.5 km. This research provides a scientific basis for water resource management, flood prediction, and adaptation in HMA.</p>","PeriodicalId":19438,"journal":{"name":"npj Climate and Atmospheric Science","volume":"27 1","pages":""},"PeriodicalIF":9.0,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143675202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We find that about 34.6% of TCs drove greening and 65.4% caused browning response of vegetation during 2000–2020. TC-induced greening is more likely for TCs originated in pre-monsoon (100%) or monsoon (62.5%) than post-monsoon with large browning response (94%). Rainfall by TCs increases soil moisture (SM) and reduces climatic water deficit (CWD) for a moisture-stressed region, and its effective utilisation by vegetation triggers the greening response. Granger Causality reveals that TC-induced rain and greening response exhibit a maximum temporal lag of 40 days. The favourable vegetation response to TCs is a new insight as it sheds light on the complex Atmosphere-Land-Ocean (ALO) interactions on a regional scale. The findings can aid to improve climate models for better policy decisions aimed at climate adaptation and sustainability on both regional and global scales.</p>","PeriodicalId":19438,"journal":{"name":"npj Climate and Atmospheric Science","volume":"19 1","pages":""},"PeriodicalIF":9.0,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143665886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we find that the influence of ENSO on the EASM has been diminishing since the early 2000s. The EASM in wind anomalies associated with the positive phase of ENSO quickly disintegrates in August, changing from an anticyclone over the western North Pacific (WNPAC) to a cyclone over the western North Pacific (WNP), which exerts significant influence on the East Asia rainfall. These weakened EASM responses are closely linked to the changes in ENSO’s rate of decay around the early 2000s. During 1977–1999, ENSO events peaking in the boreal winter frequently display a gradual decay, triggering robust positive ocean–atmosphere feedback, which extends beyond the TIO and involves the WNP. The resultant North Indian Ocean (NIO) warming develops and persists through the decaying summer, maintaining the WNPAC in August. In contrast, ENSO events exhibit a faster decay during 2000–2022, leading to a weakened ENSO-induced TIO feedback. Additionally, the WNP warms up, accompanied by the collapse of the easterly wind response, contributing to the weak summer peak in the NIO. In turn, the weak NIO warming rapidly decays, which cannot sustain the WNPAC in August. This study emphasizes the crucial role of WNP air–sea coupling in the changing influences of ENSO on the EASM.</p>","PeriodicalId":19438,"journal":{"name":"npj Climate and Atmospheric Science","volume":"8 1","pages":""},"PeriodicalIF":9.0,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143665888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
