Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.Abstract Recent work has demonstrated that convection‐permitting models often produce a greater number of precipitating convective cells compared to radar observations. Congestus‐depth cells contribute most to the bias, which are colloquially termed “popcorn convection.” This study explores warm‐phase microphysical contributions to the bias using ...

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Determining marsquake magnitudes is essential for assessing seismic activity on Mars, yet previous estimates neglect three‐dimensional (3D) scattering effects. The exceptionally long‐lasting coda of the largest recorded marsquake, S1222a, provides a unique opportunity to quantify how crustal heterogeneities affect waveform propagation and ...

Fault‐Controlled Plumbing System Beneath Lipari Volcanic Island Revealed by Seismic Matrix Imaging
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Lipari Island hosts an active magmatic–hydrothermal system, but its deep plumbing architecture remains poorly resolved due to strong seismic scattering. We apply passive seismic matrix imaging to public vertical‐component cross‐correlation functions from the dense 2018 Lipari nodal array, recovering relative‐reflectivity structures to ∼10 km ...

Decadal Reversal of Eurasian Winter Temperature Trend Linked to North Atlantic Climate Variability
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract The long‐term trend of Eurasian winter surface air temperature has undergone a distinct decadal change, shifting from a pronounced cooling trend between the late 1980s and late 2000s to a subsequent warming trend. This study demonstrates that this trend reversal is partly driven by decadal changes in North Atlantic sea surface temperature (SST)

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract The Pamir, located at the northwestern margin of the Tibetan Plateau, is undergoing E–W extension within its interior, accommodated by micro‐block motions along major fault systems; however, the mechanisms governing this modern block kinematics remain elusive.

Source‐Unbiased Subsurface Monitoring With Seismic Noise
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract This study addresses a key limitation of seismic noise interferometry for subsurface monitoring: the impact of non‐stationary sources on seismic velocity change estimates. Conventional methods rely on time‐period references, which can inherit source‐related effects when source conditions vary, biasing the estimated velocity changes.

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract This study demonstrates the intriguing and complex interplay among auroral precipitation, enhanced TEC, density irregularities, and amplitude scintillations observed during the November 2025 superstorm. For the first time, we present observations of strong amplitude scintillation across continental United States (CONUS)—nearly from coast to ...

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Large intraplate earthquakes are paradoxical because they occur far from active plate boundaries. Northern Hainan Island (South China) hosts the 1605 Qiongbei M7.5 earthquake within a volcanic province linked to the Hainan mantle plume. New shear‐wave velocity images reveal two shallow low‐velocity zones extending to ∼10 km depth: a stronger ...

Dynamic Control of Phase Matching in Nonlinear Metasurfaces Using Pancharatnam–Berry Phase
Nanophotonics, Volume 15, Issue 17, 11 September 2026.Can mechanical rotation of a metasurface control the phase of a nonlinear optical signal? In a dual‐metasurface multipass cell, a circularly polarized pump interacts repeatedly with two plasmonic metasurfaces between two mirrors. By exploiting the geometric phase, rotating one metasurface shifts the phase‐matching condition of the second‐harmonic ...

High‐Efficiency Acousto‐Optic Modulation on Non‐Suspended Thin‐Film Lithium Tantalate
Nanophotonics, Volume 15, Issue 17, 11 September 2026.We demonstrate high‐efficiency acousto‐optic modulation on a non‐suspended thin‐film lithium tantalate (LTOI) platform. By engineering acoustic modes within high‐Q resonators, the devices achieve low half‐wave voltage‐length products. This work establishes LTOI as a robust, scalable solution for integrated microwave‐photonics, combining strong ...
