Large amplitude perturbations and waves at the duskside LLBL of the magnetopause generated by an interplanetary tangential discontinuity on December 7, 2000

On December 7, 2000 a joint current sheeth and vorticity layer hit the magnetopause (MP) generating large amplitude oscillations, and wave-like perturbations observed by CLUSTER at the near dusk flank. Linear stability theory and MHD numerical simulations support the hypothesis that the waves were d...

Sumario:On December 7, 2000 a joint current sheeth and vorticity layer hit the magnetopause (MP) generating large amplitude oscillations, and wave-like perturbations observed by CLUSTER at the near dusk flank. Linear stability theory and MHD numerical simulations support the hypothesis that the waves were due to the Kelvin-Helmholtz (KH) instability. The simulation brings in light novel dynamic properties of the boundary layer under the KH excitation. © 2006 American Institute of Physics.
