The recent anomalously weak polar field does not imply a weak field at solar cycle 25 minimum

Zi-Fan Wang, Jie Jiang, Yukun Luo +3

The ongoing solar cycle 25 has progressed past its peak of sunspot numbers, being stronger than the previous cycle 24. However, the present polar field is rather weak compared to p…

Understanding mechanisms underlying solar cycle predictability with a general framework

Binghang Li, Jie Jiang, Yukun Luo

The large-scale magnetic field observed at the solar surface is produced by the interior dynamo process. Whether this surface field also provides the dominant seed for the subseque…

Effects of Various Bipolar Approximations of Active Regions on Solar Surface Magnetic Field Simulations

Yukun Luo, Jie Jiang, Ruihui Wang

The evolution of solar surface magnetic fields is essential for understanding solar activity and the underlying dynamic process. The surface flux transport (SFT) model is a widely…

Constraining the outer boundary condition for the Babcock-Leighton dynamo models

Yukun Luo, Jie Jiang, Binghang Li +2

The evolution of the Sun's large-scale surface magnetic field is well captured by surface flux transport models, which can therefore provide a natural constraint on the outer bound…

Simulation of Solar Surface Flux Transport Constrained by Magnetic Power Spectra. I. Flux Transport Parameter

Yukun Luo, Jie Jiang, Ruihui Wang

The multi-scale structure of the solar surface magnetic field is essential for understanding both the Sun's internal dynamo processes and its external magnetic activity. The surfac…
