Abstract

In the work, based on the data analysis of the interplanetary magnetic field and fluxes of solar wind charged particles for 2014 year, a set of parameters is proposed, which can be indicators of the degree of complexity of the recorded events. The basic characteristic of the considered physical systems is the dimension of the phase space. Our approach allows us to study processes in a multidimensional phase space without reducing its dimension. In the first approximation, the dimension can be interpreted as the minimum number of independent variables required to describe a physical process. In this setting, each of the phase space unit vectors has its own memory depth scale and its own stability parameter, the Lyapunov parameter. It is established that the dominant dimension of the phase space is the same for both the magnetic field and the solar wind flux and is equal to 5. The analysis of the Lyapunov exponents shows that all the observed series of processes belong to dissipative-type hyperchaos.
