Solar Wind Parameters in Periods of Solar Large-Scale Magnetic Field Reversals

The present paper investigates the behavior of solar wind basic parameters during the large-scale solar magnetic field reversal. Using the superposed epochs method for monthly averaged values of the different solar wind parameters for the last four large-scale magnetic field reversal, it is shown that during the periods of different polarities, some of the parameters as magnetic field B-x and B-y components, as well as B-scalar and solar wind speed have seasonal trend. Plasma density and pressure have differences in their magnitude during the different periods.
