Electric Current Approach Studying Both Auroral Substorms and Solar Flares Together
Frontiers in Astronomy and Space Sciences, 2020 Auroral substorms and solar flares are basically various manifestations of electromagnetic energy dissipation processes, so it is useful to consider both phenomena in terms of a chain of processes, consisting of power supply (dynamo), transmission ...

Magneto-Rossby Waves and Seismology of Solar Interior
Frontiers in Astronomy and Space Sciences, 2018 Eleven-year Schwabe cycle in solar activity is not yet fully understood despite of its almost two century discovery. It is generally interpreted as owing to some sort of magnetic dynamo operating below or inside the convection zone.

Persistence and Dynamics of an Sq‐like Mid‐Latitude Current Vortex During the May 2024 Superstorm
Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.Abstract The solar quiet (Sq) current system describes the mid‐latitude equivalent current under quiet geomagnetic conditions, but whether an Sq‐like vortex persists during intense storms remains unclear. Using dense East Asian magnetometer observations, including the Chinese Meridian Project, we reconstruct the storm‐time ionospheric equivalent ...

Can stochastic resonance explain the amplification of planetary tidal forcing?
, 2019 Repeated Grand Minima revealed by proxies of solar activity suggest that the Sun alternates between two stable states, a quiescent and an active one. If the intrinsic noise of the solar dynamo allows for a frequent switching between these stable states ...

Helioseismic Properties of Dynamo Waves in the Variation of Solar Differential Rotation
The Astrophysical JournalSolar differential rotation exhibits a prominent feature: its cyclic variations over the solar cycle, referred to as zonal flows or torsional oscillations, are observed throughout the convection zone.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.Abstract Increasing attention has been given to large‐scale disturbance electric fields in the inner radiation belt as a driver of drift‐periodic zebra stripe formations. Such disturbance electric fields have also been discussed as a possible driving mechanism of electron precipitation, transporting electrons below the inner belt and into the ...

Quiet Time Ionosphere‐Thermosphere Predictability During Sudden Stratospheric Warmings in TIE‐GCM
Space Weather, Volume 24, Issue 11, November 2026.Abstract We investigate the predictability of the ionosphere‐thermosphere (IT) region during sudden stratospheric warmings (SSWs) by using subseasonal hindcasts in the Community Earth System Model, version 2 with the Whole Atmosphere Community Climate Model (CESM2 [WACCM6]) to force the lower boundary of the TIE‐GCM.
