AI‐Based Regional Emulation for Kilometer‐Scale Dynamical Downscaling
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract An AI‐based Limited‐Area Model (LAM) is developed for dynamical downscaling over the Southern Great Plains and the southeastern United States, with strong generalization abilities under diverse boundary conditions. The model is trained using 0.25° ${}^{\circ}$, 3‐hourly ERA5 as forcings and CONUS404 as targets in 1980–2019, producing 4‐km ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract Numerical wave models are widely used for wave forecasting and hindcast data set construction; however, their outputs frequently exhibit systematic biases stemming from uncertainties in wind forcing, physical parameterizations, and bathymetry. To address this issue, a deep learning–based bias correction approach is applied to significant wave ...

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Tropical cyclones (TCs) making landfall often produce extreme precipitation with complex spatiotemporal patterns, posing major challenges to both deep learning models and numerical weather prediction (NWP) systems. This study introduces Rainflow, a conditional flow matching (CFM) based generative model for high‐resolution TC precipitation ...

QBO–TC Relationship in the Western North Pacific Is Nonstationary
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract The Quasi‐Biennial Oscillation (QBO) has been proposed as a key factor modulating tropical cyclone (TC) tracks in the western North Pacific, but its robustness remains controversial. This study revisits the QBO–TC relationship by extending the analysis period to 2024.

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Many regions worldwide, including Subtropical South America (SSA), face significant challenges from convective systems that produce severe weather. However, limited research exists on how these systems may change under future climate conditions.

ANTICYCLONIC EDDIES IN THE ALASKA GYRE (AND CAPE HORN CURRENT?)
Gayana, 2004 Sea surface height (SSH) fields, constructed from multiple altimeters, have revealed the annual generation of anticyclonic eddies around the Alaska Gyre.

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.Abstract The ability of convection‐permitting regional climate models to realistically simulate extratropical cyclones (ETCs) and associated near‐surface wind speeds and precipitation remains poorly documented. This study provides the first comprehensive evaluation of the sixth version of the Canadian regional climate model (CRCM) for this purpose over

Impact of Upper‐Level Warming on Tropical Cyclone Intensity
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Deep convection from tropical cyclones (TCs) can reach the height of the tropopause and as such an interaction between the upper troposphere and lower stratosphere is likely to occur. Such interactions have been reported in both numerical and observational studies, mainly showing that subsidence from the stratosphere into the eye of an ...
