Other Abstract

The hemispheric coupling phenomenon of solar activity cycle is a manifestation of the evolution of the solar magnetic field, discovered as early as the middle of the 20th century. From a statistical perspective, research on solar activity indicators (sunspot numbers, sunspot areas, flare index, filament and prominence, etc.) reveals that the magnetic activity in the southern and northern hemispheres shows amplitude asymmetry and phase in each solar cycle are out of sync. Up to now, the research process in this field can be summarized in three phases: (1) the guessing and confirmation phase from the early 1950s to the mid-1990s; (2) the statistical analysis phase from 1995 to 2010 looking for evolutionary laws; (3) beginning from 2011 approximately, the mechanism exploration phase using a combination of statistical analysis of observation data and numerical simulation of magnetohydrodynamics theory. The theoretical model of solar dynamo driven by this phenomenon helps to obtain basic information about the evolution of solar cycle, and also has an important value for shortand medium-term forecasting of solar activity and space weather. Here, a brief review of the historical development of magnetic solar cycle is given at first. And then the discovery and observation history of the hemispheric coupling phenomenon in the solar activity cycle are reviewed. Furthermore, the basic observation statistics of the hemispherical coupling phenomenon of solar activity at different time and space scales, as well as the research results of the hemispheric coupling theory are reviewed. Finally, we give a discussion of the future research about the hemisphere coupling of the solar activity cycle.
