Solar wind pressure and the position of the magnetopause: A Cluster perspective
Solar wind-magnetosphere interaction
MetadataShow full item record
Applying empirical reconstruction techniques to Cluster data allows to determine the varying position of the magnetospheric boundary continuously for time intervals of several hours. It has therefore become possible to examine the influence of solar wind pressure on the position of the magnetospheric boundary in more detail. In particular, one can examine the continuous correlation between solar wind pressure and the position and motion of the boundary during such a long time interval, rather than correlating discrete values of solar wind pressure and boundary location that correspond to individual magnetopause traversais, as has been done in the past. We discuss an event study to highlight the degree of solar wind ram pressure control over the magnetopause position.
