Diagnostic analysis reveals that the westward winds in the Southern (summer) Hemisphere were anomalously strong (maximum of ∼90 m/s) during December 2023, which significantly shortened the <i>e</i>-folding time of QTDW-W3, and additionally generated the QTDW-W3 critical layers at the tropical summer stratopause from December 7. These two factors contributed to the earliest amplification of QTDW-W3. In essence, the cold equatorial stratosphere triggered the exceptionally strong westward winds in the Southern Hemisphere via thermal wind balance, which was related to the enhanced upward middle-atmosphere Hadley circulation during a prolonged Arctic stratopause warming event.","PeriodicalId":12523,"journal":{"name":"Geophysical Research Letters","volume":"22 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020907","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 use SWOT observations to detect significant hydrologic changes during an unprecedented 2024 flood in southern Brazil. In the Jacuí and Guaíba Rivers, water slopes increased dramatically–up to 11 times (from 0.82 to 9.59 cm/km) and 21 times (0.31–6.58 cm/km) compared to stable conditions. SWOT-derived surface water elevations captured 99% of water level variability compared to in situ observations. Additionally, flooding in Patos Lagoon was intensified by NE–SW wind forcing, causing water levels to rise by up to 40 cm, worsening the flood event. SWOT proves a unique opportunity to understand extreme flooding events, providing new support for flood risk management in the context of climate change.","PeriodicalId":12523,"journal":{"name":"Geophysical Research Letters","volume":"74 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020962","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}

The short lifecycle of the Atlantic Niño and the lack of precursor signals beyond about one season lead time have hindered the development of forecasts with useful accuracy and lead time. In this study, we propose a new approach to Atlantic Niño forecasting that extends beyond the Atlantic region by incorporating longer-lasting precursors in the Pacific associated with El Niño-Southern Oscillation events. Using this prediction framework, we can hindcast the Atlantic Niño with skill up to three seasons in advance. Our results highlight the critical role of inter-basin interactions in shaping regional and global climate patterns, and provide new hope for improving seasonal climate prediction capabilities in the tropical Atlantic. Plain Summary Despite extensive efforts made by the climate research community, the equatorial Atlantic region, in particular the Atlantic Niño phenomenon, consistently demonstrates poor seasonal forecasting capabilities. In this study, we propose a new approach to Atlantic Niño forecasting by using longer-lasting precursors in the Pacific. The new prediction framework enables skillful prediction of the boreal summer Atlantic Niño events up to three seasons in advance. The results of our study have the possibility to reduce the existing gap in seasonal prediction for the equatorial Atlantic region by leveraging inter-basin information, particularly benefitting vulnerable communities in the tropical Atlantic basin.","PeriodicalId":12523,"journal":{"name":"Geophysical Research Letters","volume":"38 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020961","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}

It is associated with anomalously low dispersion of virtual geomagnetic poles and some high estimates of Earth's dipole moment. However, many of these strong paleointensity data are of poor or unknown quality. Here we report full-vector paleomagnetic measurements from a series of mid-Kiaman (∼282–302 Ma) lamprophyre dykes from Orkney, Scotland. A total of 258 paleointensity experiments were performed alongside rock magnetic experiments and scanning electron microscopy. Eleven dykes produced virtual dipole moment estimates indicating that the field was weak (between 0.1 and 2.9 × 10²² Am²) at 302 Ma and only moderately stronger (between 2.7 and 7.1 × 10²² Am²) at 282 Ma. These new data challenge the paradigm of a uniquely strong field in the Kiaman superchron and are especially intriguing when considered alongside recent studies of geomagnetic field behavior during the later Cretaceous Normal Superchron (∼84–121 Ma). Average dipole moment may be marginally elevated and paleosecular variation moderately suppressed during the superchrons but, in other respects, the field can appear similar to that encountered during other times. The deep-Earth conditions allowing for the generation of a geomagnetic field that is capable of weak, unstable behavior and transitory polarity inversions, while nevertheless maintaining a dominant single polarity for tens of millions of years, is not yet clear. The challenge of explaining superchrons and their geodynamic origin motivates further study integrating paleomagnetic observations with predictions from geodynamo simulations.","PeriodicalId":15864,"journal":{"name":"Journal of Geophysical Research: Solid Earth","volume":"12 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Characterizing seismic signals yields insights into source processes and Earth's structural features. Global seismic network analysis of long-period (25–100 s) surface waves has detected seismic events not identified through high-frequency body wave analysis. However, detecting long-lasting monochromatic signals with narrow spectral peaks, which carry valuable information about geological and environmental processes, remains challenging on a global scale. We developed a coherence-based approach to characterize long-period monochromatic signals on a global scale. In addition to signals originating from the Gulf of Guinea, Vanuatu islands, and a submarine volcano, we observed a previously unidentified signal originating from the Canadian Arctic, likely associated with glacier dynamics. Our approach explores long-period monochromatic seismic signals in continuous seismic data, providing a foundation for future studies to characterize the physical processes generating these signals on Earth's surface.","PeriodicalId":12523,"journal":{"name":"Geophysical Research Letters","volume":"104 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020906","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}

Gold and W mineralization in XZMP are commonly coupled, however, the Xingfengshan Au–W deposit is characterized by skarn W mineralization that is overprinted by sheeted quartz vein-hosted Au mineralization. Garnet U–Pb dating provides a maximum age limit for W mineralization at 214.8 ± 3.2 Ma (MSWD = 1.8), while biotite Ar–Ar dating indicates Au mineralization occurred at 205.2 ± 0.4 Ma (MSWD = 0.96), confirming that Au and W mineralization were decoupled. This is supported by the elevated temperature of the Au mineralizing event demonstrated by chlorite geothermometry (W = 291–346 °C vs. Au = 351–416 °C). Arsenopyrite, the main Au-hosting mineral, can be divided into three generations — Apy-1, Au-enriched Apy-2, and Apy-3. Gold occurs as invisible Au in Apy-1 and Apy-2, but as visible Au coexisting with Apy-3. The abundant chlorite, biotite, and ilmenite inclusions in Apy-1 and Apy-2, and low δ<ce:sup loc=\"post\">34</ce:sup>S<ce:inf loc=\"post\">V-CDT</ce:inf> values (Apy-1 = −8.82 to −8.44 ‰, Apy-2 = -9.57 to −7.69 ‰) suggest that they formed by fluid–rock interaction. Apy-3 is enriched in trace elements (e.g., Co, Ni, Cu) and has lower δ<ce:sup loc=\"post\">34</ce:sup>S<ce:inf loc=\"post\">V-CDT</ce:inf> values (−12.56 to −12.03 ‰), indicating the involvement of late-stage oxidized magmatic-hydrothermal fluids in its formation. This fluid remobilized invisible Au from Apy-2 and precipitated it as visible Au associated with Apy-3. The close spatiotemporal relationship between mineralization at Xingfengshan and the Baimashan composite pluton, the S isotope composition of pyrite (−4.94 to 1.18 ‰), and the metallogenic affinity of granites together suggest that the W and Au mineralization are genetically associated with the Longcangwan two-mica granite and Longtan biotite granite of the Baimashan composite pluton, respectively.

However, their impact on mode I fracture toughness (<i>K</i>_<i>Ic</i>) has been less explored. This study investigates the impact of saturating fluids on the <i>K</i>_<i>Ic</i> of three rock types: a porous siliceous sandstone (Corvio) and two high-strength, low-porosity granites (Blanco Mera and Blanco Alba). Pseudo-compact tension (<i>p</i>CT) specimens (diameter ∼50–54 mm, thickness ∼25 mm, notch depth ∼16 mm) were saturated with seven different fluids (deionized water, methanol, NaCl-saturated water, mineral oil, diesel fuel, an acidic HCl solution and a caustic NaOH solution) and tested under identical conditions. Results show that all fluids reduce <i>K</i>_<i>Ic</i>, but the extent varies with rock type and fluid properties. Aqueous fluids caused the most significant reductions, with deionized water having the greatest impact on granites (∼18%–30%) and the acid solution on sandstone (∼70%). Non-polar hydrocarbon fluids, despite their lack of reactivity, caused moderate effects attributed to poro-mechanical effects. Additionally, pH-shift experiments, involving sequential exposure to alkaline and acidic solutions, mitigated fluid-induced weakening. This behavior is hypothesized to stem from silica dissolution in the alkaline phase, followed by rapid nucleation and precipitation during the acidic phase, forming silica-rich coatings on mineral surfaces. Fracture energy was not equally distributed, with higher post-peak energy absorption due to crack bifurcation, grain rotation or friction. These findings underscore the interplay of lithological factors, fluid properties and chemical processes in fracture behavior, with implications for subsurface engineering and modeling of fluid-rock interactions.","PeriodicalId":15864,"journal":{"name":"Journal of Geophysical Research: Solid Earth","volume":"20 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142992342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 report new data on chemical compositions and He–C isotopic ratios of hydrothermal volatiles in the northern plateau. CO₂-rich samples exhibit elevated ³He/⁴He ratios (0.11 <i>R</i>_A–0.39 <i>R</i>_A) compared to crustal values, as well as displaying heavy <i>δ</i>¹³C (−4.66–0.02‰) and high CO₂/³He ratios ((36–9,400) × 10⁹), indicating in summary the occurrence of carbonate in the mantle-derived components. We have developed a coupled He–C isotope model incorporating depleted mantle (DM), recycled carbonate (RC), and crustal carbon endmember (CCE) reservoirs to explore quantitatively the nature of the hydrothermal volatiles emitted. The results of model calculations reveal an increasing proportion of RC together with a decreasing proportion of CCE from south to north that is accompanied by an increasing contribution from DM, all suggesting the presence of a carbonated mantle beneath northern Tibet. Degassing of helium from hydrothermal activities exhibits relatively high fluxes of total ³He (10⁴–10⁵ atoms/m²/s), indicating a tectonically active degassing of volatiles in the Tibetan Plateau under ongoing continental convergence between India and Asia. Systematic variations in He–C isotopes, mantle helium fluxes and RC/CEE proportions along hydrothermal activities spanning from the Himalayas to the Qaidam-Gonghe basin are consistent with a dual continental subduction model acting beneath the whole Tibetan Plateau.","PeriodicalId":15864,"journal":{"name":"Journal of Geophysical Research: Solid Earth","volume":"74 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142992341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, X-SHiELD's high resolution and explicit deep convection allowed for a detailed analysis of the warm and cold sectors, which are instead typically underrepresented in traditional CMIP models. Instead, compositing the 100 most intense midlatitude cyclones in the North Atlantic, we find that the warm sector exhibits statistically significant increases in wind speed and precipitation of up to 15% locally per degree of warming, while changes in the cold sector are less pronounced.

Reactions are only permitted among phases that are adjacent across grain boundaries and the extent of reaction at a given reaction site is scaled to the local amount of chemical affinity available to the two or three reactant phases relative to the grain boundary composition. This local affinity is dissipated as the local reaction proceeds, which changes the composition of the adjacent grain boundary “phase” and sets up chemical gradients that drive diffusion along the grain boundaries. Reactions proceed until all affinity is exhausted at which point the rock is essentially at equilibrium. Two extremes are modeled. Reaction-limited growth is modeled as infinitely rapid grain boundary diffusion whereas diffusion-limited growth is modeled by assuming that reactions proceed infinitely fast such that the supply of nutrients and removal of waste products from a reaction site is restricted by the rate of diffusion. Models are presented with model assemblages chlorite + quartz + garnet and chlorite + quartz + muscovite + biotite + plagioclase + garnet. Reaction-limited models result in garnets displaying well-formed “bell-shaped” Mn zoning profiles with all garnet crystals showing similar amounts of growth and zoning profiles. Diffusion-limited models result in mineral growth or consumption that is texture-sensitive such that the amount of consumption or production of a phase depends on the location of the crystal in the sample and the proximity of other phases. For example, the total amount of garnet continues to increase for the duration of diffusion-limited models although locally an individual garnet crystal may first grow and then be consumed. Mn zoning in models with short diffusion times display distinct “peaks” in the central garnet cores, in contrast to the bell-shaped profiles in reaction-limited models. With increasing diffusion times, these Mn zoning profiles evolve towards bell-shapes. These models demonstrate that diffusion-limited growth of garnet porphyroblasts may result in textural and compositional complexities that are not encapsulated by bulk-rock thermodynamic modeling.</p></div>","PeriodicalId":526,"journal":{"name":"Contributions to Mineralogy and Petrology","volume":"180 2","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00410-025-02201-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142995641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
