The Overlooked Role of Alongshore Beach Non‐Uniformity in Short‐Term Shoreline Variability

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Long‐term beach monitoring and satellite‐derived shoreline products are typically validated, and shoreline models calibrated, along cross‐shore transects. Open sandy beaches, however, are rarely uniform alongshore, because crescentic megacusps migrate past fixed transects, and their effect on single‐transect records remains unquantified.

Interplay Between Deep Convection and Mesoscale Gravity Waves

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 21, 16 November 2026.
Abstract Although the association between precipitation and mesoscale gravity waves (MGWs) is well documented, the feedback mechanisms governing their amplification remain difficult to isolate. This study uses convection‐permitting numerical simulations with 1–4 km grid spacing to investigate a complex MGW event that occurred over the south‐central ...

The Sting Jet in a Simulated Extratropical Cyclone [PDF]

The Open Atmospheric Science Journal, 2009
The sting jet (SJ), distinguished from warm and cold conveyor belt jets, has significant impacts on our society and economy through producing damaging surface winds. The purpose of this study is to confirm two scientific hypotheses on the SJ through diagnosing the idealized numerical simulation.

Representation of Long‐Term Observed UK Winter Precipitation Trends and Variability in UKCP18 Global Climate Models

International Journal of Climatology, Volume 46, Issue 13, 15 November 2026.
Evaluating historical precipitation trends is complicated by interactions between variability in atmospheric circulation and thermodynamic forcing. This study assesses 1901–2023 UK winter precipitation trends in UK Climate Projections 2018 (UKCP18) global climate models using dynamical adjustment to separate circulation‐driven and non‐dynamical ...

A New Hydroclimatic Signature: Negative NAO Dominance Under Weak La Niña Conditions During the 2025–2026 Northwest Africa Floods

International Journal of Climatology, Volume 46, Issue 13, 15 November 2026.
Conceptual hydroclimatic pathway linking the concurrent negative North Atlantic Oscillation (NAO) phase and weak La Niña conditions to extreme February rainfall and flash flooding in Northwest Africa. ABSTRACT The winter of 2025–2026 in Morocco exhibited a rapid hydroclimatic transition from prolonged drought to widespread flooding, representing an ...

Increasing risks of the explosive extratropical cyclones over the North Atlantic storm track: a perspective from their surface wind maxima

Environmental Research Letters
Extratropical cyclones play a crucial role in balancing the global momentum, energy, and moisture, and also, they shape the extreme weather events over the extra-tropics.

Evaluating Machine‐Learning Weather Prediction for UK Windstorm Weather Warnings

Meteorological Applications, Volume 33, Issue 6, November/December 2026.
Can machine‐learning weather prediction models simulate UK windstorms well enough to be used when providing wind weather warnings? We evaluate them against current numerical weather models, finding that they are not yet suitable to replace them, particularly when hazardous winds are linked to sharp frontal gradients and mesoscale features.

Basin‐Scale Marine Heatwave Types in the Gulf of Mexico: Wind–Humidity Controls on Latent Heat‐Loss Suppression and Ocean‐State Modulation of Vertical Thermal Structure

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract Marine heatwaves (MHWs) in the Gulf of Mexico (GoM) have become more frequent and intense, yet the mechanisms governing basin‐scale events remain incompletely understood. EOF–k‐means clustering of event‐mean sea surface temperature anomalies (SSTA) during 1982–2024 identifies four recurrent, seasonally dependent spatial regimes: two stronger ...

A Machine Learning Framework for Objective Definition and Projection of Meteorological Seasons: An Application to the Indian Subcontinent

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Meteorological seasons are typically defined through fixed calendar intervals or region‐specific thresholds, yet such approaches fail to capture the actual variability of the annual cycle. Here we present a machine learning framework that objectively detects meteorological seasons and projects their future evolution.
