Gravity Wave Activity in the Stratosphere and Mesosphere During Hurricane Sam
Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract Multi‐instrument observations of gravity wave (GW) activity during Hurricane Sam (2021) were made using AIRS (Atmospheric Infrared Sounder) satellite data, ERA5 reanalysis, and TIMED/SABER temperature profiles. Two GW extraction methods, vertical high‐pass filtering and empirical mode decomposition, were applied to quantify wave‐induced ...

Space Weather, Volume 24, Issue 6, June 2026.Abstract Ejections of magnetized plasma from the Sun, known as coronal mass ejections, can drive major geomagnetic activity if Earth‐directed, and are therefore monitored by space weather forecasters. The current focus being the forecast of the arrival time of a coronal mass ejection at Earth and the level of geomagnetic impact.

Space Weather, Volume 24, Issue 6, June 2026.Abstract To address the complex spatiotemporal characteristics of ionospheric total electron content (TEC), a bidirectional convolutional long short‐term memory network with a dynamic cross‐attention mechanism for spatiotemporal feature weighting (CASF‐BiConvLSTM) is proposed and further combined with the sliding interquartile range (SIQR) method ...

Space Weather, Volume 24, Issue 6, June 2026.Abstract ST‐Observer is a novel proposed spatiotemporal prediction model based on dynamic system theory, which has been proven to be superior to existing models in multiple spatiotemporal prediction tasks. However, its structural design results in weak time dependent modeling capabilities and a lack of frequency dependent modeling capabilities.

Statistical Properties of Small‐Scale Magnetic Flux Ropes in the Near‐Earth Solar Wind
Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract We present a statistical analysis of small‐scale magnetic flux ropes (SMFRs) observed in the near‐Earth solar wind using data from the Magnetospheric Multiscale (MMS) and Wind spacecraft, identified through an automated Grad–Shafranov reconstruction technique.

Multi‐Wavelength Transformer‐Based 24‐Hour Solar Flare Forecasting at the Active‐Region Level
Space Weather, Volume 24, Issue 6, June 2026.Abstract Solar flare forecasting remains challenging due to the complex spatiotemporal evolution of solar active regions (ARs) and the severe class imbalance associated with high‐impact events. In this work, we investigate a transformer‐based framework for active‐region–level solar flare forecasting using short sequences of multi‐wavelength ...

Space Weather, Volume 24, Issue 6, June 2026.Abstract The geomagnetic storm on 1 June 2025 generated pronounced large‐scale traveling ionospheric disturbances (LSTIDs) over China, captured by dense GNSS networks. It has been unclear whether network real‐time kinematic (NRTK) positioning, which relies on spatial interpolation from multiple reference stations, remains effective under such extreme ...
