An Atmosphere–Land–Ocean Coupled Global NWP System: Performance Evaluation for Potential Operational Use

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract This study assesses the influence of ocean–atmosphere coupling on short‐ and medium‐range forecasts of the July 2024 Indian summer monsoon using the newly configured coupled NCMRWF Unified Model (C‐NCUM). Forecasts are evaluated against the operational atmosphere–land model (NCUM) using GPM rainfall, OSTIA SSTs, and reanalysis‐derived moisture

Opposite Trends of Eddy Kinetic Energy in the Tropical Indo‐Pacific Ocean Since the 1990s

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Oceanic mesoscale eddies are pivotal in redistributing mass and heat. Despite a warming‐induced increase in global oceanic stratification, previous studies have reported a global increase in mesoscale eddy activity, particularly in eddy‐rich regions, pointing to a complex and regionally contingent response to climate change.

Accelerated European Summer Warming Driven by Atmospheric Circulation Changes in Response to Aerosol Forcing

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Compared to observations, climate models underestimate the recent increase of European summer temperatures, due to an underestimation of Quasi‐stationary Rossby Wave (QSW) trends over Europe. This is partially due to unpredictable internal variability and partially due to an underestimation of the predictable signal in response to external ...

Weak 21st‐Century AMOC Response to Greenland Meltwater in a Strongly Eddying Ocean Model

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Climate models project that the Atlantic Meridional Overturning Circulation (AMOC) will weaken in the 21st century, but the magnitude is highly uncertain. Some of this uncertainty is structural, as most climate models neglect increasing meltwater from the Greenland ice sheet and do not explicitly capture mesoscale ocean eddies.

GOLD Nighttime Limb Observations: A New Data Set for Investigating the Altitude‐Latitude Structure and Temporal Variability of the Equatorial Ionization Anomaly

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Using NASA's Global‐scale Observations of the Limb and Disk (GOLD)'s Dark Limb Mode (DLM) observations, we provide a multi‐year characterization of nighttime Equatorial Ionization Anomaly (EIA) morphology and variability. From geostationary orbit, GOLD measures OI 135.6 nm limb radiance at ∼33°E and ∼128°W longitudes, yielding routine, time ...

The Tropical Indo‐Pacific and North Atlantic Precursors for the Interannual Variation of Extreme Humid‐heat Days in the Yangtze River Basin

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Extreme humid‐heat events pose a major hazard across the Yangtze River Basin (YRB), yet their underlying mechanisms and seasonal predictability remain insufficiently understood. Here, using observational diagnostics and coupled model experiments, we identify three independent drivers in the tropical Indo‐Pacific and subtropical North Atlantic ...

Non‐Uniform Reduction of the North Atlantic Tropical Cyclones in Response to the AMOC Weakening Under External Freshwater Forcing

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract We investigate the North Atlantic (NA) tropical cyclone (TC) response to a substantial weakened Atlantic Meridional Overturning Circulation (AMOC) under external freshwater forcing using a high‐resolution coupled model. With explicit TC trackings instead of indirect inferences from large‐scale environmental changes, we detect a non‐uniform ...

Monitoring the Colonisation Dynamics of Rugulopteryx okamurae on Algal Communities in the Northwestern Mediterranean Sea

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.
ABSTRACT Biological invasions are a major driver of biodiversity loss, causing profound and often irreversible ecological changes. Among these invaders, the brown alga Rugulopteryx okamurae provides a striking example. Since its arrival in 2016 in Calanques National Park (Marseille, southern France), it has drastically transformed underwater landscapes
