ENSO Teleconnections Modulated by the State of the Equatorial Atlantic and Indian Oceans
Abstract Equatorial sea surface temperature anomalies have profound impacts on tropical and extra-tropical sub-seasonal and seasonal weather variability. While extensive research explored the impacts of El Niño-Southern Oscillation (ENSO) and its diversity on the global teleconnections, the…

Subseasonal precipitation prediction over East Asia using an adaptive bias correction model: methodology and evaluation
Abstract Accurate and reliable subseasonal precipitation forecasts are critical for disaster prevention and mitigation, particularly in densely populated regions like East Asia. However, substantial gaps remain between the reliability and accuracy of dynamical model forecasts and societal demands…

Spaceborne forest height in China buffers short-term drought stress but loses protection in prolonged aridity
Abstract Drought stress has significant impacts on the structure and carbon cycling processes of forest ecosystems. Forest height (H), as a key vegetation structural parameter, plays a crucial yet poorly understood role linking vegetation responses to drought stress. This study, utilizing…

Reevaluating historical tsunami hazards from the Makran subduction zone and local seismic sources along the Western Indian margin through numerical modelling
Abstract The western coast of India is highly vulnerable to tsunami hazards due to its geographical proximity to the Makran Subduction Zone (MSZ), one of the most seismically active margins of the northern Indian Ocean. Moreover, during the Late Holocene, the Great Rann of Kachchh (GRK) along the…

Impact of satellite-based ice skin temperature initialization on Arctic winter forecasts using the Korean integrated model
Abstract Ice skin temperature (IST) is critical for representing surface energy exchange in Arctic, yet its initialization in operational numerical weather prediction (NWP) systems is often oversimplified, typically inherited from background states or prescribed as spatially uniform values, because…

Beyond the reporting of disturbed areas: the use of Deter to analyze the spatiotemporal patterns of forest degradation in the Amazon
Abstract The Brazilian Amazon, a critical component of Earth’s climate regulation and biodiversity, has been increasingly affected by forest degradation, a process less monitored than deforestation. This study examines the recurrence and spatiotemporal patterns of forest degradation in the Legal…

Reply to: No evidence for a 10-m historical tectonic uplift at Mangalia, (Romanian Black Sea coast): Comment on Drăgușin et al. (2025) by Vespremeanu-Stroe et al.
Abstract This reply addresses the comment by Vespremeanu-Stroe et al. on our paper which offered broad evidence for the existence of high amplitude vertical displacements at Mangalia, Romania, during the 18th–19th centuries. The comment proposes an alternative storm/tsunami origin for the…

Increased mixed layer salinity during the monsoon intraseasonal Oscillation in the Northern Bay of Bengal
Abstract The northern Bay of Bengal (BoB) exhibits low mixed layer salinity accompanied by strong intraseasonal variability, primarily driven by the Indian Summer Monsoon and monsoon intraseasonal oscillation (MISO). Notably, the northern BoB shows concurrent increases in mixed layer salinity and…

Assessing machine-learning-based weather forcing in significant wave height prediction
Abstract This study evaluates Pangu-Weather, a machine-learning-based weather prediction (MLWP) model, for its ability to reduce errors in numerical predictions of significant wave height (SWH). SWH predictions from the SWAN wave model were driven by 10 m wind fields from Pangu-Weather, and error…

Assimilation impact of the temperature on the super-rotation obtained by cross-link radio occultation measurements of the Venus atmosphere
Abstract Impacts of temperature assimilation on the Venus atmosphere are investigated by the observing system simulation experiments assuming cross-link radio occultation measurements of the Venus atmosphere (CROVA). Synthetic temperature data are prepared by a Venusian general circulation model…

Penghu Fan and Gaoping Fan: the depositional systems developed during passive margin–active margin transition offshore SW Taiwan
Abstract This study characterizes for the first time the two largest submarine fans surrounding Taiwan, the Penghu Fan and the Gaoping Fan, based on detailed mapping of depositional elements through newly integrated MCS data. These sedimentary bodies, previously unrecognized due to the deformation…

Spatial and temporal preferences for afternoon precipitation over morning soil moisture in global storm-resolving simulations
Abstract This study firstly examines both spatial and temporal preferences for afternoon precipitation over morning soil moisture using global storm-resolving simulations from two state-of-the-art km-scale Earth system models: the ICOsahedral Non-hydrostatic (ICON) and integrated forecasting system…

Assessing drought changes in China under a CO2 removal scenario
Abstract Understanding regional drought responses to CO2 removal is critical for carbon-neutral pathways, yet remains poorly understood for China. To address this gap, we developed a bias-corrected and spatially downscaled SPEI dataset from multi-model CO2 removal experiments to evaluate drought…

Climatic aridity modulates the spatial variations in the responses of terrestrial water budget terms to El Niño–Southern Oscillation
Abstract The El Niño–Southern Oscillation (ENSO) triggers precipitation anomalies, which are not evenly distributed across other terrestrial water budget terms, including runoff, evapotranspiration (ET), and terrestrial water storage change (TWSC). This uneven distribution represents a significant…

A variable-resolution unstructured spatio-temporal graph neural network: an application to very short-range weather forecasting in Guangdong, China
Abstract The increase in extreme weather events has raised the demand for very short-range forecasts in Guangdong, the most populous province in China. Although global AI-based weather forecasting models provide strong medium-range guidance, they remain suboptimal for regional very short-range…

Development of a ground motion model for Taiwan using XGBoost and its implementation in seismic hazard assessment
Abstract This study utilizes the XGBoost model integrated with the Flatfile database, strong ground motion records derived from the Taiwan Strong Motion Instrumentation Program (TSMIP), to establish a crustal ground motion model (GMM) in forms of PGA, PGV, and spectral acceleration. When evaluating…

Energetics of monsoon low-pressure systems in stylized simulations of reduced mean monsoon precipitation through orography forcing
Abstract Monsoon low pressure systems (LPS) are synoptic scale disturbances that form over South Asia during the summer monsoon season and often produce extreme precipitation events, causing disastrous floods. Numerous modelling and observational studies have confirmed the role of convection as a…

Enhanced hyperspectral classification for geological mapping based on spatial–spectral novel framework of vision transformers and mamba models on PRISMA data at Arabian–Nubian Shield
Abstract Lithological mapping of arid Precambrian basement underpins mineral exploration across the Arabian-Nubian Shield (ANS), where rugged, poorly accessible exposures make field campaigns slow and costly, and where serpentinites, ophiolitic mélange, granitoids and hydrothermal alteration of…

Net contributions of multiple oceanic warm and cold thermal events to tropical cyclone intensity revealed by idealized coupled simulations
Abstract The ocean serves as the energy source for tropical cyclones (TCs), and a TC typically encounters multiple oceanic warm and cold events during its lifecycle. While most existing studies emphasize individual thermal events, the net contribution of multiple warm and cold events to TC…

Reassessed changes in the thermal structure below Hokkaido: implications for slab metamorphism and earthquakes
Abstract Accurate assessment of the changing thermal structure of megathrusts at the global scale is difficult because the subduction regime depends on the three-dimensional (3-D) geometry of slabs. Although the slab dip has been studied extensively, the specific implications of subduction…
