A statistical study was carried out on the characteristics of storm-time bulk ion upflows at high-latitude topside ionosphere,with observations from DMSP F13 and F15spacecraft during58 geomagnetic storms(-472nT≤Min.Dst≤-71nT)in the period of 2001—2005.Analysis shows that,during the geomagnetic storms,topside ionospheric ion upflows were primarily detected in the cusp and night-time auroral region.In the northern hemisphere,high-speed(≥500m·s-1)up-flowing ions were frequently observed at altitudes above 65° MLat beforemagnetic noon,and high-speed ion up-flowing region was extended to lower latitude with slightly higher velocity after magnetic noon.In the southern hemisphere,however,high-speed upflowing ions could be detected everywhere before midnight.It was found that storm-time ion upflows at high-latitude topside ionosphere are usually accompanied by electron/ion heating,during which electron heating predominated.Analysis of O+density variation indicates that upflowing ions observed by DMSP spacecrafts during storms are mainly from topside ionosphere.It is suggested that electron heating is an important driving force for storm-time ionospheric upflowing ions.
