Animated Summary: Shear Waves (avi, 9.2M) Simulation showing
the development of tailward-propagating shear waves along the
magnetopause in an MHD simulation driven by a constant solar
wind of velocity 600 km/s (contours = constant magnetic field
strength; color scale = azimuthal electric field).
Animated Summary: Pressure Variations (avi, 9.2M) Simulation
showing the effect of a 3 mHz, 10% density perturbation
superposed on a 600 km/s solar wind.
