Ionospheric Response to Magnetic Storms in the South Atlantic Anomaly Region

Kalvala Ramanuja Rao


The ionospheric responsc to magnctic storms is studied during the -ascending branch of solar cyele in the South Atlantic Geomagnetic Anomaly region (SAGAR). It is sean that a positive phascesets in after about 12 hours after the
Storm sudden commoncemeñt (SSC) and persists for about 72 hours thereafter.The effective neutral winds are strongly equatorwards during the main and early recovery phase and appear to be due to particle precipitation into the region.
