Abstract

Available databases containing data about the state of interstellar medium close to the Earth’s orbit allows to carry out statistic alanalysis of the solar wind parameters distribution. Spiral structure of the interplanetary magnetic field (IMP) is confirmed. Distribution of the mean value of complete induction of the IMP is shown to be anisotropic. Induction is minimal when the vector of the IMP is close to the line “Earth–Sun”, but it reaches maximum when the vector is perpendicular to the line “Earth–Sun”. Such analysis was carried out for different phases of the solar cycle and different heliocentric distances. Spatial distribution of the solar plasma velocity vector is obtained too. Velocity of the solar wind varies depending on the direction of the solar wind velocity vector.
