Capturing Typhoon Rapid Intensification and Abrupt Recurvature Using an IAU‐Based 4DVar Scheme
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Dynamic imbalances in model initialization severely constrain the predictability of the rapid intensification (RI) and abrupt track recurvature of tropical cyclones (TCs). In this study, the effectiveness of an incremental analysis update (IAU)‐based four‐dimensional variational (4DVar) data assimilation scheme in forecasting Typhoons Doksuri ...

Quantifying the Role of 3D Fault Geometry Complexities on Slow and Fast Earthquakes
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Traditional models of slow slip events (SSEs) oversimplify fault geometry, although imaging shows subduction faults are segmented and complex. We examine how fault interactions control slip behavior using 3D quasi‐dynamic simulations of two parallel faults with uniform rate‐weakening friction accelerated by hierarchical matrices.

Unprecedented Open‐Ocean Polynya in Breid Bay, East Antarctica in Winter 2024
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract We document an unprecedented winter open‐ocean polynya in the Breid Bay, on 4 August 2024, attaining a maximum area of 89,121 km2. Prior to opening, sea‐ice concentration declined from ∼96% in early July to below 25% by 30 July 2024, indicating substantial preconditioning of the winter ice cover.

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Fault‐slip reversals indicate transient stress changes and may illuminate earthquake preparation processes. Here we present high‐resolution observations of sub‐millimetric creep and slip reversals on the Altaquelle Fault, a Quaternary normal fault in the southern Vienna Basin, preceding a regionally significant intraplate earthquake sequence ...

Systematic Overestimation of Global Peak Runoff Synchronization in CMIP6 Models
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Synchronous flooding across distant regions can amplify socioeconomic impacts. As the hydrological cycle intensifies, flood synchronization appears to be expanding, yet predictive understanding beyond gauged basins remains limited. We analyze the global synchronization of annual peak runoff (a proxy for flooding) using gridded data sets and ...
