[65.11] MHD Modeling of ICMEs

D. Odstrcil (University of Colorado/CIRES and NOAA/SEC), V. J. Pizzo (NOAA/SEC)

Recent advances in numerical methods and computer systems makes it possible to tackle complicated, more realistic dynamic phenomena appearing in the heliosphere. Representative simulations of large-scale structures require consideration of the preexisting structured ambient solar wind, realistic treatment of the launch of transient disturbances, and the consequent interaction of multiple ambient and transient structures. We will review recent progress in this area at NOAA/SEC, with special attention being given to the three- dimensional distortion of shocks and ICMEs (interplanetary counterparts of coronal mass ejections) propagating within the streamer belt and to effects generated during collisions of magnetic flux ropes and interplanetary shocks. Numerical results will be presented as evolving global structures as well as temporal profiles of plasma parameters at different observing points and line-of-sight images of light scattered from density structures.
