THE ANALYSIS OF THE RELATIONSHIP BETWEEN MAGNETIC FIELD GLOBAL INDICES (SYM, ASY) AND AURORAL ELECTROJET INDICES (AU, AL) UNDER THE ACCOUNT OF PARAMETERS OF A SOLAR WIND AND AN INTERPLANETARY MAGNETIC FIELD

The connection of the symmetric and asymmetrical parts of the ring current (SYM, ASY) with auroral electrojets (AU, AL) at the main and recovery phases of a geomagnetic storm is found. There has been determined the role of magnetosphere-ionospheric current systems in generation of asymmetry of the magnetic field on the ground in particular sectors of the local time. The study was conducted in view of parameters of Solar Wind (PSW) and interplanetary magnetic field (IMF) for various time delays of indices SYM, ASY relatively AU, AL. There has been revealed the efficiency of the influence of state in the Solar Wind on the development of the ring current and auroral electrojets. For this purpose the correlation study of connection of SYM, ASY, AU, AL indices with particular parameters of the near-earth space is carried out.
