Validation of ECMWF Ensemble Forecasts of Sea Surface Latent and Sensible Heat Fluxes in the Pacific Arctic Against Saildrone Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Estimates of sea‐surface latent and sensible heat fluxes using in situ observations are very rare in the Arctic Ocean. Saildrone Explorer uncrewed surface vehicles (saildrones) were deployed in the Bering, Chukchi, and Beaufort Seas from May–October 2019.

Stochastic parameterization: uncertainties from convection [PDF]

, 2011
In 2005, the ECMWF held a workshop on stochastic parameterisation, at which the convection was seen as being\ud a key issue. That much is clear from the working group reports and particularly the statement from working group\ud 1 that “it is clear that a stochastic convection scheme is desirable”. The present note aims to consider our current\ud status

Significance of Size‐Dependent Hygroscopicity Parameterization for Aerosol‐Cloud Interactions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Aerosol‐cloud interactions (aerosol indirect effects) are the most significant source of uncertainties in the effective radiative forcing (ERF) due to aerosols which can act as cloud condensation nuclei (CCN). Uncertainties in the indirect effect can result from systematic uncertainties in aerosol water uptake (hygroscopicity).

Vertical Wind‐Pressure Covariance and its Vertical Gradient in Atmospheric Boundary Layers From Large Eddy Simulations

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Atmospheric wind‐pressure covariances (e.g., vertical wind‐pressure covariance, w′p′‾ $\overline{{w}^{\mathit{\prime }}{p}^{\mathit{\prime }}}$) affect boundary‐layer energetics and pressure‐related corrections, yet their sign and vertical structure are inconsistently reported.

Weak Tropical Tropospheric OH Response to Idealized ENSO

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The hydroxyl radical (OH) is a key oxidant for methane. Previous studies suggest that OH exhibits interannual variability linked to the El Nino–Southern Oscillation (ENSO), but the sign, magnitude, and underlying mechanisms of this response remain uncertain.

Cloud response to lateral interactions from convective strength-variable neighbors

Geoscience Letters
The organization of convective clouds plays a key role in convective system development, yet the interactions between neighboring cloud entities remain unclear.

Pacific Warming Pattern Discrepancy Linked to Spurious Rainband in Climate Models

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The distinctive pattern of observed Pacific surface temperature trends, with cooling in the east and intensified warming in the west, departs from the more uniform warming anticipated by climate models. The apparent inability of climate models to simulate this warming pattern limits our ability to understand why it is occurring and to predict ...

Momentum Decoupling Drives Low‐Wind Events During Heatwaves in China: A Hybrid Explainable Machine Learning and Dynamical Modeling Approach

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Compound heatwave and low‐wind (HW‐LW) events increasingly threaten China's energy security. Analysis of 2000–2023 data reveals these compound extremes account for 18.5% of total heatwaves, with their annual frequencies nearly doubling in recent years.

Anomalous Sea Ice Retreat in the Refreezing Western Arctic by a 30‐Year Record Cyclone in October: Oceanic, Atmospheric, and Wave Influences

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract An extreme Arctic cyclone (AC) in October 2022 reached a record‐low pressure of 955 hPa and caused unusual wave‐induced sea‐ice breakup in the Canada Basin, making it the strongest event in the western Arctic in 30 years. Here we examine how this event interrupted freeze‐up by quantifying sea‐ice retreat associated with atmospheric and oceanic

A Deep‐Learning‐Based Wind Gust Estimation Scheme in Complex Terrain

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Accurate prediction of gusts is critical for risk mitigation, but the turbulent processes that generate gusts are unresolved in conventional numerical weather prediction models. Here we introduce a deep‐learning‐based wind gust estimation scheme (DL‐GUST) that uses archived diagnostics from the Weather Research and Forecasting (WRF) model ...
