Pattern Recognition of West African Monsoon Extreme Rainfall Events Using Convolutional Neural Networks

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Accurate prediction of extreme rainfall and dry events remains a major challenge in West Africa due to the complex and non‐linear dynamics of the monsoon system, which involve interactions among local convection, large‐scale circulation, ocean‐atmosphere coupling, and intra‐seasonal variations.

The Effect of Hydraulic Fracturing on the 2021 Ms 6.0 Luxian Earthquake as Revealed by Deformation and Numerical Simulations

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract This study investigates whether hydraulic fracturing contributed to the 2021 Ms 6.0 Luxian earthquake in the Sichuan Basin. Time‐series InSAR analysis of multi‐temporal Sentinel‐1 data reveals coseismic deformation associated with the 2021 Luxian earthquake and localized uplift near hydraulic fracturing platforms.

Shallow Modeling and Site‐Amplification From Telecommunications Fibers in Istanbul

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract We use pre‐existing fiber‐optic telecommunications fibers in Istanbul, Türkiye, to generate a seismic velocity model of the subsurface down to 100 m depth, and estimate site‐amplification in the region. We collect ambient noise, predominantly from urban traffic, along the 8 km segment fiber, extract Rayleigh wave dispersion curves, and use a ...

Investigating the Impact of the Spatially Heterogeneous Surface Dust Cover on Martian Global Dust Event Occurrence

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The observed inter‐annual variability of Global Dust Events (GDE) occurrence on Mars remains challenging to understand and therefore to predict. Several hypotheses have been investigated so far, but a central aspect seems to be missing: How the heterogeneity of the surface dust cover and regolith particle size distributions relate to regional ...

Characterization of Curves that Lie on a Geodesic Sphere or on a Totally Geodesic Hypersurface in a Hyperbolic Space or in a Sphere [PDF]

, 2018
The consideration of the so-called rotation minimizing frames allows for a simple and elegant characterization of plane and spherical curves in Euclidean space via a linear equation relating the coefficients that dictate the frame motion.

The Global Contribution of Individual Submarine Groundwater Discharge Components to the Ocean

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Saline submarine groundwater discharge (SSGD) contributes to ocean chemistry through water‐rock interactions as seawater circulates in coastal aquifers. Its components, driven by different mechanisms, exhibit varying residence times and degrees of chemical alteration, so constraining solute fluxes requires quantifying each component.

Reduced Cerebral Blood Flow in the Early Chronic Phase of Recurrent Concussion Among Female Collegiate‐Aged Athletes

Human Brain Mapping, Volume 47, Issue 9, June 15, 2026.
In a sample of healthy collegiate‐aged athletes, we observed that greater lifetime concussion history was associated with global and frontotemporal hypoperfusion, an effect seen exclusively in female athletes. These findings suggest a potentially modifiable, sex‐specific marker that could support earlier detection and intervention in concussion‐related
