| Zusammenfassung |
| From a limited number of observations it appears that vorticity is
a common feature in the inner plasma sheet. With the four Cluster
spacecraft and the four PEACE instruments positioned in a tetrahedral
configuration, for the first time it is possible to directly estimate
the electron fluid vorticity in a space plasma. We show examples of
electron fluid vorticity from multiple plasma sheet crossings. These
include three time periods when Cluster passed through a reconnection
ion diffusion region. Enhancements in vorticity are seen in association
with each crossing of the ion diffusion region. |
