SHOCK WAVE INTERACTIONS WITH VISCOSITY OBSERVED AFTER THE CORONAL MASS EJECTION ACTIVITIES OCCURRED ON DECEMBER 18, 1999 AND APRIL 4, 2001

Abstract

As a result of solar magnetic activity, shock waves and geomagnetic storms can be created by the discharge of magnetic field and plasma from the solar atmosphere, such as coronal mass ejections, or CMEs, and the solar wind. Shock waves are known to occur as solar particles shift from the supersonic to the subsonic zone. The interaction of shock waves and viscosity is largely relied on in space weather broadcasts, notably in the supersonic case of compressible gas flow. Thus, the primary purpose of this paper was to apply the modeling work from [1] to look for the viscosity consequence in the shocks discovered after the CMEs on December 18, 1999, and April 4, 2001.
