How the circulation can affect neutral composition at solar minimum: possible implications for the F2 region and topside ionosphere
Abstract
Geomagnetic activity was very low during 2008-2009, yet there were strong disturbances in GUVI neutral composition during this period that are associated with relatively small changes in geomagnetic activity. In this presentation, we e describe these composition variations and associate them with changes in circulation. In addition, we consider their possible effects on the F-region and topside ionosphere.
