Abstract The freezing of a magnetic field into a turbulent flow of a conducting fluid or plasma at high magnetic Reynolds numbers can lead to an exponential increase in magnetic energy due to the accumulated hydrodynamic energy. This process is described by the magnetohydrodynamic dynamo theory and can be conventionally divided into two regimes, in the first of which the average magnetic field increases

Abstract The study of a reliable series of sunspot observations has allowed formulation of a scenario for the sustainable development of solar cyclicity over the past ~190 years. This scenario predicts a change in the level of sunspot activity in epochs of increased or lowered solar activity with selected transition periods, which gives three different modes of the total magnetic field generation of

On the Role of the Neutral Plasma Component in the Electric Current Dissipation and the Formation of a Transition Region in the Solar Atmosphere Geomagn. Aeron. (IF 0.6) Pub Date : 2023-12-01
Abstract A mechanism of the formation of a transition region between the chromosphere and the corona, which relies on the dissipation of electric currents in a partially ionized plasma is proposed. It has been demonstrated that the transition region experiences the enhanced level of Joule dissipation due to an increased Cowling resistivity caused by ion-neutral particle collisions. This leads to effective
