A discussion about some aspects of the solar-terrestrial systems coupling with regard to space weather effects

Abstract

In the present paper we present a discussion about some aspects of the solar-terrestrial system coupling with regard to space weather effects based on some recent studies of energetic particles precipitation at the South American Magnetic Anomaly and the cosmic noise absorption seem by image riometers, and abnormal enhancement of the equatorial sporadic E-layers density during the recovery phase of magnetic storm.
