The evolution of field aligned wave Poynting flux in the storm time inner magnetosphere

We present a study of the temporal and latitudinal evolution of field-aligned wave Poynting flux intensity at high (Polar Spacecraft) altitudes and its role in transporting energy in the storm-time inner magnetosphere. In particular, the role such waves play in the acceleration of low latitude precipitating auroral electrons as well as ion outflows is examined in the context of their evolution over a period of days, encompassing pre-storm, main phase, recovery, and post storm time periods. The waves discussed herein have a strong Alfvénic component. Alfvén waves have been shown to be associated with ion outflows [Wygant et al. 2000, 2002; Chaston et al., 2007] and thus may be expected to play a key role in mass loading the magnetosphere as well as in ring current dynamics. The role of such waves in the context of the inner magnetospheric dynamics will be examined by correlating these waves with ion outflows, Dst, and stretching the of the magnetic field topology as determined from the Tsyganenko 2001 model. Relevant implications for understanding radiation belt dynamics will be explored.
