The authors model the properties of the ion flow in the high [beta][sub i], inner plasma sheet, during periods when geomagnetic activity is relatively low. They adopt the approach that the plasma sheet can be modeled in terms of bursty bulk flows (BBF's), irrespective of the auroral electrojet index. They then model the average flow pattern in the inner plasma sheet after the obvious BBF events have been removed from the data. The average flow properties found do not represent the instantaneous flow fields however, as there are large variances observed, even in the non-BBF part of the flow field. They are able to generate the same average flow patterns with their model, taking into account flow due to corotation, crossed field flow, and diamagnetic drift, as the T87 model.
