The study of a CME induced seven substorms and their associated scintillation behavior at South Pole
Abstract
An Earth-directed coronal mass ejection (CME) had been erupted by Sun on 16 July, 2013. The CME induced particles arrived on Earth's magnetosphere on 18 July, 2013. On 18 and 19 July, 2013, there were CME induced 7 substorms. We are introducing a new method of Travelling Ionospheric Disturbances (TIDs) analysis using two B-spline basis functions of degree 4, together with the Global Positioning System (GPS), Total Electron Content (TEC) data available for South Pole. Ionospheric scintillation patterns, induced due to these disturbances are showing growth, expansion and the recovery phase of the substorm. Islands of enhanced TIDs are found in the great consistency with the ionospheric amplitude and phase scintillation occurrence and their spatial and temporal spread.
