Weak 21st‐Century AMOC Response to Greenland Meltwater in a Strongly Eddying Ocean Model
Abstract Climate models project that the Atlantic Meridional Overturning Circulation (AMOC) will weaken in the 21st century, but the magnitude is highly uncertain. Some of this uncertainty is structural, as most climate models neglect increasing meltwater from the Greenland ice sheet and do not explicitly capture mesoscale ocean eddies.

Abstract Ocean microstructure measurements collected during three austral summers (2023–2025) along the Antarctic continental slope off Dronning Maud Land show enhanced subsurface mixing. Mean turbulent dissipation between 100 and 800 m depth is an order of magnitude higher than in the open ocean, with an extreme event reaching 3×10−6 $3\times 1{0}^{-6}

Unraveling the Fine‐Scale Tapestry of Solar Wind at 1AU
Abstract Solar wind is a complex network of distinct magnetic flux tubes, each contained and separated by a current sheet. In this study, more than 50,000 current sheets in the solar wind are identified and characterized for the first time, using multi‐point Cluster observations during solar minimum and maximum intervals.

Calibration of a Neural Network Ocean Closure for Improved Mean State and Variability
Abstract Global ocean models exhibit biases in the mean state and variability, particularly at coarse resolution, where mesoscale eddies are unresolved. To address these biases, parameterization coefficients are typically tuned ad hoc. Here, we formulate parameter tuning as a calibration problem using Ensemble Kalman Inversion (EKI).

Abstract The diurnal variation of regional precipitation events (RPE) over the Middle and Lower Yangtze River Basin (MLYRB) significantly affects human activities and serves as a key reference for weather forecasting. Here, the diurnal variation of summer RPE over MLYRB under two monsoonal synoptic types and their regulatory factors have been addressed.

Ground‐Truthed Fiber‐Optic Sensing Reveals Internal Tide Bores Over Madeira's Steep Slope
Abstract We demonstrate the combined utility of distributed acoustic sensing (DAS) and repeat conductivity‐temperature‐depth (CTD) profiling for observing internal tide dynamics over a sloping seafloor. While DAS has been widely proposed as a method to infer ocean temperature variability from seafloor cables, quantitative in situ validation has been ...

Abstract Mesoscale convective systems (MCSs) are key contributors to heavy rainfall in the East Asian summer monsoon, yet their statistics and internal structure remain difficult to simulate, even in convection‐permitting models (CPMs). This study evaluates the performance of the newly developed Unified Forecast System Double‐Moment microphysics scheme

ABSTRACT The Mesosphere and Lower Thermosphere establish an essential connection between Earth's lower atmosphere and upper atmosphere because wind patterns essential for atmospheric movement also influence energy distribution and chemical movements during geomagnetic storms that disrupt satellite operations and space weather prediction systems.
