A Machine Learning‐Based Model of Three‐Dimensional Ion Fluxes in the High‐Altitude Earth's Northern Cusp

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Magnetic reconnection at the dayside magnetopause is the primary pathway for transferring mass, momentum, and energy from the solar wind into the terrestrial magnetosphere. Previous studies have shown that the spatiotemporal dynamics of dayside magnetic reconnection can be inferred remotely from properties of Earth's cusps, specifically their ...

Magnetic Reconnection Driven by the Impact of a Magnetosheath High‐Speed Jet

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract High‐speed jets (HSJs) are transient structures in the magnetosheath characterized by enhanced dynamic pressure. While recent studies report that HSJs trigger magnetic reconnection at the magnetopause, whether they can directly drive reconnection within the magnetosheath remains an open question.

Wave Signals From Rapidly Intensifying Typhoons Mark Vortex Adjustment Rather Than Robust Ionospheric Coupling

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Rapidly intensifying typhoons can generate atmospheric waves, but nearby neutral‐atmosphere and ionospheric anomalies need not form a robust cross‐layer coupling chain. We examine 75 western North Pacific rapid‐intensification events during 2018–2023.

YOLO‐Based Detection and Localization of Rocket Induced Traveling Ionospheric Disturbances

Journal of Geophysical Research: Machine Learning and Computation
During rocket launches, atmospheric disturbances significantly impact the ionosphere, generating Traveling Ionospheric Disturbances (TIDs). These disturbances can affect radio communications and navigation systems and may pose risks to high‐speed ...

Observational Analysis on the Relationship Between Chorus Waves and MeV Microburst Electron Precipitation

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Microbursts are thought to be a key contributor to radiation belt electron loss, with chorus waves considered a primary driver of this precipitation. However, the conditions under which chorus waves produce MeV electron loss remain poorly constrained.

Impacts of Mid‐Latitude Ionospheric Dynamics on RF Applications During the November 2025 Superstorm Event

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 ...

Ionospheric disturbances and their impacts on HF radio wave propagation

, 2021
The multi-frequency multipath observations of temporal variations in the Doppler spectra and signal amplitudes of HF radio waves reflected from the ionosphere, which accompanied ionospheric disturbances caused by an ionospheric storm, an earthquake, and ...
