Polarity Reversal of the Polar Magnetic Fields in Solar Cycle 25
Yin Li, Shuhong Yang, Yuzong Zhang +4
The polar magnetic field polarity reversal is a key signature of solar cycle evolution, and precise determination of its timing is crucial for dynamo theory validation and solar cy…
Variations of the vector magnetic structures in the solar polar regions observed by Hinode
Shuhong Yang, Chunlan Jin, Qiao Song +7
Using the polar vector magnetic field data observed by Hinode from 2012 to 2021, we study the long-term variations of the magnetic flux, the flux proportion of different polarities…
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 Solar Origin of an Intense Geomagnetic Storm on 2023 December 1st: Successive Slipping and Eruption of Multiple Magnetic Flux Ropes
Zheng Sun, Ting Li, Yijun Hou +12
The solar eruption that occurred on 2023 November 28 (SOL2023-11-28) triggered an intense geomagnetic storm on Earth on 2023 December 1. The associated Earth's auroras manifested a…
