Uninterrupted solar full-disk observations at high cadence for more than two solar cycles have significantly advanced our understanding of the plasma motion below the surface and various phenomena occurring at and above the surface. These have led to many new discoveries by expanding our knowledge of how the solar interior and atmosphere are interconnected. At the same time, they have raised many new challenges to our understanding of interior dynamics and magnetic field generation.
For example, we do not precise understanding of when and where active regions will emerge. In addition, studies indicate puzzling and contradictory results regarding the cell structure of poleward meridional circulation and at what depth these flows return towards equator. Furthermore, observations covering the last two deep and extended periods of low magnetic activity raise several additional questions about our understanding of solar dynamo. Do we have precise knowledge that can be applied to forecast the strength and timing of the future solar cycles with some confidence?
The research topic aims to
(i) Summarize how MDI, HMI and GONG observations enriched our understanding of solar flows and fields;
(ii) Understand links between interior and atmosphere of the Sun;
(iii) Characterize processes responsible for magnetic field generation, transport of dynamo-generated magnetic flux, flux emergence to the surface and its global distribution;
(iv) Highlight hidden problems in the understanding of various solar phenomena and interpreting observations;
(v) Discuss new techniques and methods for improving data analysis
(vi) Outline how solar flows and fields can provide new insight into solar activity forecasting, e.g., strength of the forthcoming cycle, emergence of active regions, precursors of eruptive events and space weather.
To achieve these goals, this issue will include original work and the review articles. We encourage submissions based on both theoretical as well as observational aspects of the above-mentioned topics.
