A Probabilistic Framework for Incorporating Helioseismic Far-Side Active Regions into SFT Models
Bibhuti Kumar Jha, Lisa A. Upton, K. D. Leka +5
Surface Flux Transport (SFT) models are routinely used to model the Sun's photospheric magnetic field and provide inner boundary conditions for coronal and heliospheric models, yet…
Oscillatory Phase and Acoustic Travel-Time Inconsistencies Measured between SDO/HMI and GONG Dopplergrams
Junwei Zhao, Ruizhu Chen, S. P. Rajaguru +1
We investigate the causes of discrepancies in meridional-circulation measurements derived from the helioseismic observations by the Helioseismic and Magnetic Imager onboard the Sol…
Long-Term Clustering Pattern of Solar Active Regions and Their Potential Connection with Magneto-Rossby Waves
Junwei Zhao, Ruizhu Chen, Aimee A Norton
Large solar active regions (ARs) tend to be long lived and spatially clustered, with repeated emergence occurring in persistent solar activity nests over extended timescales. By an…
Active-region Modulation of Subsurface Meridional Flows and Magnetic Flux Transport on the Sun
Anisha Sen, S. P. Rajaguru, Ruizhu Chen +2
Using time-distance helioseismology applied to 14-years of SDO/HMI observations spanning solar cycle 24 and rising phase of cycle 25, we present evidence that meridional flows in t…
Structural Tilting and Depth-Dependent Behavior of Equatorial Rossby Waves
Oana Vesa, Junwei Zhao, Ruizhu Chen
Over the past decade, solar equatorial Rossby waves have been unambiguously identified and are considered potential diagnostics of solar interior dynamics. We investigate their inc…
