Mechanisms for Meridional Propagation of Global Mesoscale Ocean Eddies Within a PV‐Based Dynamic Framework

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Mesoscale eddies are crucial for global heat and tracer transport, yet the mechanisms underlying their meridional movement remain unclear. Here, we combine satellite observations, idealized numerical experiments, and theoretical modeling to investigate these mechanisms. We demonstrate that the meridional eddy movement is strongly linked to the

Absolute vorticity advection and potential vorticity of the free troposphere as synthetic tools for the diagnosis and forecasting of cyclogenesis

, 1997
The dynamics of a case of cyclogenesis over the central Mediterranean associated with heavy precipitation, especially over the southeast Aegean Sea, have been investigated on the basis of the analyses of two meteorological parameters, namely, the ...

Global Hotspots of Stalling Extratropical Cyclones

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Extratropical cyclones (ETCs) are primary drivers of extreme weather in the mid‐to‐high latitudes. We introduce a new classification of particularly impactful events—“stalling” ETCs—defined by slow movement combined with intense precipitation. Using cyclone tracking data, we find that stalling ETCs cluster systematically along the east coasts ...

Intensification of Eddy Energetics Modulates Seasonal Trends and Spatial Variability in the East Australian Current System

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The East Australian Current (EAC) separates near 32°S, forming large, energetic eddies. While the seasonal cycle of the EAC system is well documented, the season‐specific long‐term trends in its separation latitude, eddy energetics, and their spatial heterogeneity remain poorly understood.

What Is Triggering Ice in Mixed‐Phase Clouds: A Process Analysis With ECHAM6.1‐HAM2.3 Using the Factorial Method

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Mixed‐phase clouds can be found at temperatures between 0 and −38° ${}^{\circ}$C and consist of supercooled cloud droplets and ice crystals. The phase of mixed‐phase clouds is crucial for the radiation budget, which determines the atmosphere's energy balance.
