Direct numerical simulation of sand particles transporting in the atmospheric Ekman boundary layer

Flow
Abstract This study presents a direct numerical simulation that investigates the transport mechanisms of sand particles in the neutrally stable atmospheric Ekman boundary layer (AEBL). The simulation models the AEBL in a half-channel flow, taking into account the Earth's rotation and adding a Coriolis term to the Navier–Stokes equations.

Tracing Coupled GCM Equatorial Pacific Climatological Biases via Surface Flux Adjustments

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Global weather and climate forecasts hinge on the ability of coupled general circulation models (CGCMs) to simulate ocean‐atmosphere interactions in the tropical Pacific. Yet most CGCMs develop tropical Pacific biases, such as an overly‐intense equatorial cold tongue (ECT), which limit their simulation skill.

Distinct Roles of Surface Flux Changes in Driving Model Spread of Dynamic Sea‐Level Projections in Different Regions

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Dynamic sea‐level change (ΔDSL) $({\Delta }\mathrm{D}\mathrm{S}\mathrm{L})$ is a key process in shaping the pattern of future sea‐level rise. CMIP6 models predict a range of ΔDSL ${\Delta }\mathrm{D}\mathrm{S}\mathrm{L}$ under 1% increase of CO2 ${\text{CO}}_{2}$ per year.

Polar Front System Variability and Its Control on Export Rain Ratio Over the Past 800 ka: Implication for Atmospheric pCO2 Changes

Paleoceanography and Paleoclimatology, Volume 41, Issue 3, March 2026.
Abstract Little is known about long‐term variability in the organic carbon to carbonate carbon export rain ratio, despite its key role in the global carbon cycle. Here, we reconstruct glacial‐interglacial changes in the sedimentary rain ratio over the Southern Ocean, using micropaleontological (coccoliths and foraminifera) and geochemical (CaCO3, Total

Geochemical Evidence for Retention of Particulate Carbon and Mercury Across the Romaine Land‐Ocean Aquatic Continuum

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract The land‐to‐ocean aquatic continuum (LOAC) carries contaminants, nutrients, and particulate carbon (C) from inland aquatic systems to the sea, which can impact regional biogeochemical budgets and local ecosystem health. Climate change and other anthropogenic influences (e.g., hydroelectricity) will affect the LOAC across varied watersheds ...

Trade‐offs across life history stages and social association types shape winter communal roosting in a long‐lived raptor

Journal of Animal Ecology, Volume 95, Issue 3, Page 430-442, March 2026.
Our study demonstrates how life history trade‐offs and pair bonds influence winter roosting in red kites. Analysing long‐term GPS data from 216 individuals, we reveal marked behavioural plasticity in communal roosting: young, non‐breeding males are most likely to join communal roosts, whereas breeding pairs predominantly roost together near their ...

Listen Closely: Measuring Vocal Tone in Corporate Disclosures

Journal of Accounting Research, Volume 64, Issue 1, Page 229-277, March 2026.
ABSTRACT We examine the usefulness of machine learning approaches for measuring vocal tone in corporate disclosures. We document a substantial mismatch between the widely adopted actor‐based training data underlying these approaches and speech in corporate disclosures.

Variation in Interactive Gestures by Visual Occlusion and Topic Complexity: Evidence for a Subconscious Theory of Gesture

Cognitive Science, Volume 50, Issue 3, March 2026.
Abstract Gestures are often categorized into types: iconics, metaphorics, and pantomimes (having representational relationships with spoken semantics), deictics (i.e., pointing), emblems (having their own conventional meaning), and beats (temporally coinciding with spoken content for emphasis).

A Comparative Study of Velocity and Transport Estimates Along the Oleander Line Between Bermuda and New Jersey

Earth and Space Science
The Oleander project, a program to monitor upper ocean currents between Bermuda and New Jersey, started in fall 1992, at about the same time modern satellite altimetry began. This study has two purposes.
