 It is shown that the perturbed perturbations propagating at an angle with respect to the velocity vector of the medium play a dominant role in the development of Kelvin-Helmholtz instability. It is noted that the generation of a large number of stable MHD modes at the interface of the plasma can lead to the realization of the turbulent state of the plasma, which is observed in the tail of the Earth's magnetosphere from spacecraft. In order to predict the short-term prediction of solar flares that play an important role in the formation of space weather, the process of occurrence and development of low-frequency instability of kinetic Alven and kinetic ion-sound waves in the plasma of solar magnetic loops is investigated. The concept of occurrence of global hydrodynamic fluxes of matter and generation of global magnetic fields in the solar convective zone is proposed. The results obtained on the latitudinal evolution of surface zonal currents correlate well with the behavior of the deep zonal currents obtained as a result of processing the observed data from spacecraft. The transfer of particles across a constant magnetic field by a random isotropic electric field with a finite correlation time and an anisotropic static random electric field is investigated. The proposed approach may be useful for describing the processes of proton transfer in the Earth's magnetosphere.
