Reduced Wind Power on Oceanic Near‐Inertial Internal Waves in a Warming Climate

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Wind power on oceanic near‐inertial internal waves (WI ${W}_{\mathrm{I}}$) is one of the major energy sources to sustain ocean turbulent diapycnal mixing. However, its response to global warming remains poorly understood. Using a high‐resolution climate simulation that simulates WI ${W}_{\mathrm{I}}$ reasonably well, we show that under a high ...

Evaluation of AMSU‐A and MHS Radiance Assimilation Strategies in MPAS–JEDI 4DEnVar for Mountain‐to‐Plain Convection Over Beijing, China

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract To improve numerical prediction of mountain‐to‐plain (MTP) convection over the Beijing region, this study uses the MPAS–JEDI four‐dimensional ensemble‐variational (4DEnVar) data assimilation system on a global 3–60 km variable‐resolution mesh to evaluate assimilation strategies for radiances from the Advanced Microwave Sounding Unit‐A (AMSU‐A)

Evaporation and Cold Pools Beneath Trade Cumulus Clouds

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The sources of air and water vapor in the tropical trade‐wind Atlantic subcloud boundary layer (SBL) are analyzed using in situ measurements of temperature, specific humidity, and stable water isotopologues (HDO and H218O) from shipboard observations in January‐February 2020.

Deep Convective Trace Gas Transport to the UTLS: Highlighting Remote Sensing and Modeling Challenges With ACCLIP Campaign In Situ CO Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract China is a major source of anthropogenic emissions, with important implications for chemical composition and aerosol processes in the upper troposphere and lower stratosphere (UTLS), particularly within the Asian Summer Monsoon (ASM) anticyclone.

Comparison of a drainage flow model with the data of Manins and Sawford

, 1981
SIGMET is a system of computer codes developed to simulate mesoscale meteorology in regions containing complex terrain. This study attempts to quantify the effects of temperature differences along valley slopes, vegetation, humidity, and large scale ...

3D Water Vapor Signature of Tropical Storms: GNSS Tomography of the 10 Most Severe Rainfall Events in Hong Kong 2015–2025

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract Monitoring water vapor during extreme events is crucial for understanding atmospheric physics, as well as for improving the prediction of severe weather and enhancing early warning systems. The major gap in monitoring water vapor during extreme events lies in the limited spatial and temporal resolutions of existing techniques.

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.

Track‐Dependent Links Between Tropical Cyclones and Extratropical Predictability in Physical and AI Models

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Global medium‐range weather forecasts suffer occasional failures (“busts”) linked to tropical cyclones (TCs). We investigate TC influences on extratropical predictability by comparing forecasts from a physics‐based model (ECMWF‐IFS) and an AI‐hybrid model (Google‐NGCM) initialized near TC genesis.

Intercomparison of mesoscale meteorological models

, 2004
In the framework of the RAPHAEL EU project, a series of past heavy precipitation events has been simulated with different meteorological models. Rainfall hindcasts and forecasts have been produced by four models in use at various meteorological services or research centres of Italy, Canada, France and Switzerland. The paper is focused on the comparison

Evaluation and Future Changes of Mesoscale Convective Systems Over the Conterminous United States in High‐Resolution Global and Regional Simulations

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Mesoscale convective systems (MCSs) play a central role in producing extreme precipitation over the conterminous United States (CONUS), yet their simulation and future evolution remain elusive. Here we present a comprehensive, observation‐constrained evaluation of MCSs during 2001–2020 using multisource satellite and in situ observations, ERA5
