The Dynamics of Magnetic Rossby Waves in the Quasigeostrophic Shallow Water Magnetohydrodynamic Theory

The Astrophysical Journal
The dynamics of magnetic Rossby waves are investigated by applying a quasigeostrophic shallow water magnetohydrodynamic system, which is linearized with respect to both uniform background flow and uniform magnetic field.

Resonant Forcing by Solar Declination of Rossby Waves at the Tropopause and Implications in Extreme Events, Precipitation, and Heat Waves—Part 1: Theory

Atmosphere
The purpose of this first article is to provide a physical basis for atmospheric Rossby waves at the tropopause to clarify their properties and improve our knowledge of their role in the genesis of extreme precipitation and heat waves.

Distinct El Niño Flavors and SAM Variability Modulate Surface Melt Over the Ross Ice Shelf

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Our study investigates how different flavors of El Niño, centered on the Eastern Pacific (EP) and Central Pacific (CP), and their interaction with the Southern Annular Mode (SAM) modulate surface melt events over the Ross Ice Shelf (RIS). Using satellite‐based melt observations, ERA5 reanalysis, high‐resolution regional model simulations, and ...

To Align or Not to Align? That Is the Question

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Previous studies have shown that vertically misaligned circulations are commonly found in weaker tropical cyclones (TCs) below hurricane strength, whereas TCs of hurricane intensity more typically exhibit vertically aligned vortices. Thus an important step in the TC intensification process is achieving a vertically aligned circulation.

Subseasonal Tropical Convection Characteristics in the Energy Exascale Earth System Model Version 2

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Accurate simulation of subseasonal tropical moist convection remains a key challenge for Earth system models. The difficulties stem from the reliance of cumulus cloud processes on model parameterizations and the need to represent the multiscale nature of interactions among clouds, radiation, moisture, circulation, and surface energy fluxes ...

On the Tropical Nature of an Intense Mediterranean Cyclone in the Ocean‐Atmosphere System

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The Mediterranean basin hosts a large number of cyclones every year. Among them, some rare cases named medicanes present similarities with tropical cyclones but their dynamical characteristics are debated. The ocean‐atmosphere dynamics of Medicane Ianos (2020) are studied here through km‐scale fully coupled ocean‐wave‐atmosphere simulations ...

A Strictly Geostrophic Product of Sea‐Surface Velocities From the SWOT Fast‐Sampling Phase

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract While geostrophy remains the simplest and most practical balance to extract velocity information from sea‐surface height anomaly (SSHa), confusions remain within the oceanographic community to what extent this balance can be applied to altimetric observations with the launch of the Surface Water and Ocean Topography (SWOT) satellite. Given the

The Role of the Heterogeneous Variation of East Asian Subtropical Jet in the 2024 Heatwave Over Yangtze‐Huaihe River Basin

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Yangtze‐Huaihe River Basin (YHRB) has witnessed severe heatwaves in summer 2024, characterized by extremely high temperatures during both daytime and nighttime. Based on the daily maximum and minimum temperature data from the China Meteorological Administration, three dominant heatwave periods were identified over YHRB in summer 2024 ...
