Relationship between probability distribution of geomagnetic pulsations and their generation mechanism

For the main types of nonlinear processes in plasma models of functional characteristics of increment nonlinearity of the increase in vibrations and propagation medium on the whole are obtained. The distributions of vibration amplitude probabilities in case of their source modelling by autogenerator and nonlinear amplifier of noises are determined. It is shown that the distributions are characterized by the presence of zeros in characteristic function, and the number and location of zeros is related to generation mechanism
