A Model for Recommending Historical Similar Events in Forecasting CME Geoeffectiveness

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Coronal mass ejections (CMEs) are among the key solar eruptive activities, triggering space weather disturbances. Thus, forecasting their geoeffectiveness has become a research focus. This study constructs a model to recommend similar events for forecasting the geoeffectiveness of CMEs.

Development and Cancellation of Long‐Duration Positive Ionospheric Storms: Both Changes of the F2‐Layer Peak Height and O/N2 Ratio Can Be Decisive

Space Weather, Volume 24, Issue 7, July 2026.
Abstract For decades, two competing hypotheses on the key drivers of mid‐latitude long‐duration positive ionospheric storms (LDPS) have been considered: (a) an increase of the F2‐layer peak height (hmF2) and (b) an increase in the atomic oxygen to molecular nitrogen density ratio (O/N2).

Validation of the IRI‐2020 Model Topside Ionosphere Options Through COSMIC‐1 and COSMIC‐2 Radio Occultation Profiles Collocated With Ionosonde Observations

Space Weather, Volume 24, Issue 7, July 2026.
Abstract This study validates the four topside ionosphere model options included in the latest release of the International Reference Ionosphere (IRI‐2020) model: IRI‐2001, IRI‐2001cor, IRI‐NeQuick, and the default IRI‐COR2. To assess their ability to reproduce the topside profile while minimizing uncertainties associated with F2‐layer peak modeling ...

Large, Long‐Lasting Mid‐Latitude Geomagnetically Induced Currents During a Moderate Geomagnetic Storm

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Geomagnetically Induced Currents (GICs) are a key space weather hazard to ground‐based infrastructure, and can cause mis‐operation or even equipment failure. The solar wind interacts with the Earth's geomagnetic field, causing the magnetic field at ground level to vary with time.

A Novel Deep Learning Model for High‐Latitude Ionospheric Convection Using SuperDARN Data

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Plasma convection at high latitudes is a key manifestation of magnetosphere–ionosphere coupling and serves as a critical indicator of space weather conditions. The Super Dual Auroral Radar Network (SuperDARN) provides essential data on ionospheric convection.
