Mesoscale Eddy Currents Reshape the Spatial Distribution of Wave Height in the Southern Ocean

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Mesoscale eddy currents influence ocean surface waves, but their imprints on wave height remain poorly described by observations. Here, we examine significant wave height (SWH) variations associated with more than 42,000 mesoscale eddies in the Southern Ocean using along‐track Jason‐3 altimeter measurements.

Synthetic Aperture Radar (SAR)‐Based Evaluation of Tropical Cyclone Wind Profiles and a Theory‐Based Radius of Maximum Wind Estimation

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Accurate wind profiles and radius of maximum wind (Rmax ${R}_{\max }$) are critical for reconstructing realistic tropical cyclones (TCs) to predict extreme ocean conditions, including storm surges and waves. Leveraging the expanding Synthetic Aperture Radar (SAR) database, we conducted the first comprehensive evaluation of commonly used TC ...

Validation of Sea Surface Winds From the Space-Borne Radiometer COWVR

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This study aims to validate sea surface wind data derived from the compact ocean wind vector radiometer (COWVR) onboard the International Space Station. The COWVR, a fully polarimetric and two-look microwave radiometer, provides wind direction and speed ...

A pilot variational coupled reanalysis based on the CESAM climate model

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 776, April 2026 Part A.
Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.

The role of soil moisture in the inland penetration of Indian monsoon low‐pressure systems

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 776, April 2026 Part A.
We use the Advanced Weather Research and Forecasting model to examine the role of soil moisture in the inland penetration of Indian monsoon low‐pressure systems (LPSs). We find that LPSs penetrate deeply into India despite a dry land surface; however, their inland penetration is adversely affected when there is a reduction in the total surface heat ...

Assimilation of reprocessed ERS scatterometer data into ECMWF weather analysis on the Mediterranean Sea [PDF]

Advances in Geosciences, 2005
Since the launch of ERS-1 in 1991 and ERS-2 in 1995, carrying a C-band Scatterometer, a data set of more than thirteen years of backscattered signal from the Earth surface is available for exploitation.

Medicane characteristics from high‐resolution satellite radar observations

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 776, April 2026 Part A.
This study uses high‐resolution observations from satellite synthetic aperture radar (SAR) to reveal that medicanes, cyclones with tropical features in the Mediterranean basin, have dynamical characteristics with attributes comparable with those of tropical cyclones of similar intensities, but smaller outer sizes and Rossby numbers.

Assimilation of solar‐induced fluorescence satellite observations in the European Centre for Medium‐Range Weather Forecasts integrated forecast system

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 776, April 2026 Part A.
This work demonstrates the potential of the assimilation of satellite solar‐induced fluorescence (SIF) retrievals at eight‐day and 0.1° resolutions in the integrated forecast system (IFS), developed at the European Centre for Medium‐Range Weather Forecasts (ECMWF), at global scale, to provide a more realistic representation of the vegetation temporal ...
