Special features modes with a discrete spectrum were investigated in the framework of this model. The equations of small oscillations of the plasma column of circular cross section with a helical magnetic field were obtained. The resulting equation allows analysis of small-scale MHD perturbations across the magnetic field. Conditions for the spread of ULF waves in inhomogeneous plasma configurations were found. The conditions of stability and generation of discrete perturbation in the direction of the inhomogeneity partially analyzed. According to the measurements of the equatorial satellite Atmospheric Explorer-E properties of acoustic-gravity waves, caused by the movement of the solar terminator were investigated in the range of atmospheric heights of 250-400 km. The predominance of wave mode, which moves in synchronism with the terminator was found. The model to generate global magnetic fields of the Sun in its internal volume it has been established within the framework of the theory of laminar kinematic dynamo.
