This study quantifies over 90% of TCG events are influenced by northward‐propagating intraseasonal oscillations (ISOs), which transports enhanced low‐level vorticity, reduced vertical wind shear, mid‐level moisture and warm sea surface temperature from the equator to BoB. Most TCG events occur within 20 days after the equatorial intraseasonal convections, highlighting the latter as one early‐warning indicator. Diagnostics reveal the biweekly westward‐propagating equatorial Rossby (ER) waves help channel energy from the intraseasonal envelope into developing tropical disturbances for 86% cyclogenesis. These westward Rossby waves appear over Indochina‐South China Sea 5–10 days before TCG, also serving as a potential TCG indicator. By identifying the synergistic impact of ISOs and ER waves, this study offers scientific guidance for improving subseasonal prediction in this high‐risk region.","PeriodicalId":12523,"journal":{"name":"Geophysical Research Letters","volume":"97 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145215779","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 identify potential tsunami deposits in the Guangdong‐Hong Kong‐Macao Greater Bay Area that occurred in 1555 ± 135 CE using a multidisciplinary approach. The inverted 14C ages of organic matter in sediments, consistent dating of shells, and increased coarse‐grained content imply that a rapid, high‐energy event occurred in the Greater Bay Area. The presence of shell fossils, bimodal grain size distributions, the absence of laminar textures, and an increased concentration of the marine‐derived biomarker brassicasterol in the sediment sequence collectively suggest that these sediments are likely deposits from a tsunami. Tsunami simulations further indicate that larger earthquakes from the Manila Trench could be responsible for this tsunami in the Greater Bay Area. Our findings provide preliminary evidence that tsunamis may be a critical natural hazard concern for the densely populated Greater Bay Area.","PeriodicalId":12523,"journal":{"name":"Geophysical Research Letters","volume":"1 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145215769","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}

Using a more accurate algorithm of detecting convective overshooting and 10 years of high‐resolution data, this paper investigated how aerosols affect convective overshooting, focusing on its long‐term patterns, three‐dimensional microphysical structure of precipitation such as particle size and concentration, as well as the relationship with extreme weather. Results show that convective overshooting occurred more frequently and intensely in the Maritime Continent, exhibiting a significant increasing trend. Aerosols exerted a stronger influence on convective overshooting during water vapor sufficient seasons, and polluted conditions produced larger but sparser raindrops, with raindrop diameters increasing by 1.2–1.76 times while concentration decreased by 20%. Moreover, aerosols enhanced convective overshooting impact on rain rates and lightning by 20% and 50%, respectively, nearly doubling the spatial influence area.","PeriodicalId":12523,"journal":{"name":"Geophysical Research Letters","volume":"32 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145215707","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}

Existing methods often depend on prior knowledge about the timing, location, or duration of such events, limiting their versatility. This study introduces ClimBurst, an approach to detect climate bursts (unusually high or low values of climate variables) without prior assumptions about their temporal duration. ClimBurst offers the ability to: (a) identify climate bursts of any duration within the time series of single locations, (b) link climate bursts across neighboring locations, and (c) analyze the spatio‐temporal propagation of these anomalies. Applying ClimBurst to sea surface temperature data from the Mediterranean Sea (1960–2021) shows some detected hot bursts and anomalies coincide in time with known severe marine heatwaves. ClimBurst also shows how detected hot (cold) bursts are spatio‐temporally connected and this connected bursts have increased (decreased) in duration, intensity, spatial extent and frequency historically.","PeriodicalId":12523,"journal":{"name":"Geophysical Research Letters","volume":"8 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145215706","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}
