Cluster and TC-1 observation of magnetic holes in the plasma sheet
Lucek, E.; Dunlop, M. W.; Carr, C. +10 more
Magnetic holes with relatively small scale sizes, detected by Cluster and TC-1 in the magnetotail plasma sheet, are studied in this paper. It is found that these magnetic holes are spatial structures and they are not magnetic depressions generated by the flapping movement of the magnetotail current sheet. Most of the magnetic holes (93%) were obse…
Spatial distribution of rolled up Kelvin-Helmholtz vortices at Earth's dayside and flank magnetopause
Berchem, J.; Escoubet, C. P.; Eastwood, J. P. +21 more
The Kelvin-Helmholtz Instability (KHI) can drive waves at the magnetopause. These waves can grow to form rolled-up vortices and facilitate transfer of plasma into the magnetosphere. To investigate the persistence and frequency of such waves at the magnetopause we have carried out a survey of all Double Star 1 magnetopause crossings, using a combin…
