Abstract
Self-organization is a property of any nonlinear, dynamic, dissipative system that evolves under the influence of external forces and positive feedback. Self-organization leads to the creation of order from chaos, thus reducing the entropy of the system. As a result, numerous small elements and/or short-lived elements form structures with large spatiotemporal scales. One very important property of a nonlinear, dissipative system is intermittency in space and time, which means that the system is capable of spontaneous transition to a critical state, the so-called state of self-organized criticality (SOC). In this state, small fluctuations can become an impetus for an avalanche of any scale. The object of our research, a constantly evolving convective zone with a magnetic field and turbulent plasma flows, is an ideal example of a nonlinear, dynamic, dissipative system. This review is devoted to the systematization of recent studies on the identification and study of self-organization in the processes of the generation, evolution, and dissipation of magnetic fields on the Sun.
