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…

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…

Long-term variation of the solar polar magnetic fields at different latitudes

Shuhong Yang, Jie Jiang, Zifan Wang +10

The polar magnetic fields of the Sun play an important role in governing solar activity and powering fast solar wind. However, because our view of the Sun is limited in the eclipti…

Meridional flow in the solar polar caps revealed by magnetic field observation and simulation

Shuhong Yang, Jie Jiang, Zifan Wang +10

As a large-scale motion on the Sun, the meridional flow plays an important role in determining magnetic structure and strength and solar cycle. However, the meridional flow near th…

The Sun's Magnetic Power Spectra over Two Solar Cycles. \uppercase\expandafter{\romannumeral2}. Cycle Dependence of Active Region, Magnetic Network, and Their Relation

Yukun Luo, Jie Jiang, Ruihui Wang

The multi-scaled solar magnetic field consists of two major components: active regions (ARs) and magnetic network. Unraveling the cycle-dependent properties and interrelations of t…

Toward a live homogeneous database of solar active regions based on SOHO/MDI and SDO/HMI synoptic magnetograms.II.parameters for solar cycle variability

Ruihui Wang, Jie Jiang, Yukun Luo

Solar active regions (ARs) determine solar polar fields and cause solar cycle variability within the framework of the Babcock-Leighton (BL) dynamo. The contribution of an AR to the…

Towards a live homogeneous database of solar active regions based on SOHO/MDI and SDO/HMI synoptic magnetograms. I. Automatic detection and calibration

Ruihui Wang, Jie Jiang, Yukun Luo

Recent studies indicate that a small number of rogue solar active regions (ARs) may have a significant impact on the end-of-cycle polar field and the long-term behavior of solar ac…
