Iono‐PhyTAU: A Lightweight Global Ionospheric TEC Prediction Model Based on Temporal Attention Unit and Physical Condition Constraints of the Ionosphere

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Ionospheric Total Electron Content (TEC) is the primary error source causing signal delay in Global Navigation Satellite Systems (GNSS). High‐precision TEC prediction is essential for positioning, navigation, and space weather monitoring. Although deep learning models including ConvLSTM, ConvGRU, and Transformer have advanced TEC forecasting ...

Long‐Lived Equatorial Plasma Bubbles Persisting Into the Afternoon Over the Pacific Sector During the Recovery Phase of the April 2023 Geomagnetic Storm

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Equatorial plasma bubbles (EPBs) are typically nighttime ionospheric irregularities, and their persistence into daytime sectors remains insufficiently understood. Here, we investigate long‐lived EPB‐related plasma depletion structures over the Pacific sector during the recovery phase of the 23–25 April 2023 geomagnetic storm using Formosa ...

Did Space Weather Delay the 10:05 p.m. Train Departure From Exeter on 18 October 1841?

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Although the Carrington Event of 1859 is typically cited as the first extreme space weather event of the scientific era, it is not the earliest example of modern human technology being impacted by geomagnetic activity. The literature includes reliable accounts of disturbances to telegraph equipment during geomagnetic storms dating to the late ...

Rapid Surface Intensification of the Gulf Stream Since 2014

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The warm, swift Gulf Stream (GS) plays a key role in shaping weather and climate patterns across the North Atlantic. Using 31‐year (1993–2023) of continuous satellite altimeter observations, we identify a pronounced intensification of the free‐flowing GS after its separation from the coast beginning around 2014 and persisting thereafter ...

ED‐Autoformer: A New Model for Precise Global TEC Forecast

Space Weather
Total electron content (TEC) is a key parameter for characterizing ionospheric morphology and significantly impacts the Global Navigation Satellite System. The ionosphere responds dramatically to solar and geomagnetic activity, leading to substantial TEC

Forecast of Ionospheric TEC Maps Using ConvGRU Deep Learning Over China

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
In this article, we propose a convolutional gated recurrent unit (ConvGRU) deep learning method to forecast ionospheric total electron content (TEC) over China based on the regional ionospheric maps (RIMs) from 2015 to 2018.

Observations of the Latitude and Frequency Distributions of Equatorward‐Propagating Chorus Waves

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Rising‐tone chorus elements are traditionally known to grow from low frequencies and extend to high frequencies. Using high‐resolution waveform measurements from the Van Allen Probes, we report a novel observation: equatorward‐propagating chorus waves at a few degrees in latitude are observed at high frequencies only.

Effect of the 1 December 2023 Geomagnetic Storm on SPP Performance in China

Space Weather
Geomagnetic storms, precipitated by solar phenomena such as coronal mass ejections (CMEs), profoundly disturb the Earth's magnetic field, impacting satellite‐based navigation systems.
