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…
Solar active region scaling laws revisited
Guilherme A. L. Nogueira, Robertus Erdelyi, Ruihui Wang +1
The systematic variation of solar active region (AR) properties with their magnetic flux has been the subject of numerous studies but the proposed scaling laws still vary rather wi…
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…
Mutual Validation of Datasets for Analyzing Tilt Angles in Solar Active Regions
Lang Qin, Jie Jiang, Ruihui Wang
The tilt angle of solar active regions (AR) is crucial for the Babcock-Leighton type dynamo models in the buildup of polar field. However, divergent results regarding properties of…
