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 ...

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.

The extratropical transition of Hurricane Erin (2001): a potential vorticity perspective

Meteorologische Zeitschrift, 2004
The Ertel potential vorticity (PV) is a powerful tool that provides insight into the development and evolution of weather systems. In this study the extratropical transition of Hurricane Erin (2001) is investigated from a PV perspective using operational

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 ...

The extratropical transition of tropical cyclones. Part I: Cyclone evolution and direct impacts [PDF]

, 2017
Extratropical transition (ET) is the process by which a tropical cyclone, upon encountering a baroclinic environment and reduced sea surface temperature at higher latitudes, transforms into an extratropical cyclone.

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.

Contrasting Atmospheric River detection frameworks reveal distinct thermodynamic responses at high northern latitudes

Weather and Climate Extremes
This study assesses the relationships of Atmospheric Rivers (ARs) and extratropical cyclones with relative thermal degree day (TDDrel) variability and precipitation across the Northern Hemisphere high latitudes (40–90°N).
