英文摘要 | Factors related to two sources of energy input to the ionosphere, the Poynting flux associated with both quasistatic fields (S-dc) and Alfvenic fluctuations (S-ac), and the soft electron precipitation, are investigated to evaluate their correlations with the O(+)and the H(+)outflows in the dayside cusp region by using recalibrated FAST/Time-of-Flight Energy, Angle, and Mass Spectrograph (TEAMS) data during the 24-25 September 1998 geomagnetic storm studied by Strangeway et al. (2005, ). The Poynting flux and the soft electron precipitation are well correlated with ion outflow flux in the dayside cusp region.S(dc)shows the highest correlation with the O(+)outflows, while it is the electron number flux that correlates best with the H(+)outflows. The Alfvenic waves play an essential role in accelerating outflows. The averaged O+/H(+)flux ratio is 3.0 and is positively correlated to the Poynting flux, suggesting that the O(+)flux increases more strongly with the energy input. |
