Differential Rotation for Different-sized Sunspot Groups Early Observed by the OGAUC
The Astrophysical Journal, 2023 Solar differential rotation is an important ingredient of the solar dynamo model, not only because the solar rotation profile is one of the key inputs in a solar dynamo model, but also because it imposes constraints for the solar dynamo model.

Duskside F-region dynamo currents: its relationship with prereversal enhancement of vertical plasma drift [PDF]
Annales Geophysicae, 2010 From magnetic field observations by CHAMP we estimate F-region dynamo current densities near the sunset terminator during solar maximum years from 2001 to 2002.

Space Science Reviews, 2008 We shortly review the basic observational facts concerning the solar dynamo. Then, a brief overview of our current understanding of the large-scale evolution of the magnetic field of the Sun is proposed, showing, in particular, some successes and difficulties of the mean-field models.

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 ...

Understanding the solar dynamo [PDF]
Astronomy and Geophysics, 2004 olar magnetic activity is observed on a wide range of scales, from the intriguingly regular and well-ordered large-scale field, to much more complex small-scale structures. In this article we shall primarily be concerned with the large-scale features, and the associated large-scale dynamo that is responsible for their occurrence.

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.

Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract A set of fresh Equatorial Plasma Bubbles (EPBs) formed during pre‐sunrise hours in the Southeast Asian sector amid the recovery phase of May 2024 geomagnetic storm. They offered new insights into their formation mechanism. This study used Total Electron Content (TEC) and Rate of TEC Index maps over Indonesia, along with ionosondes in Thailand ...

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.
