Simulation of Global Plasma Transportation using DyFK Model

The ionosphere/magnetosphere density changes during the magnetic activities and the ultimate ionospheric ion outflow are spectacular space weather phenomena that have significant influences on the global plasma circulation and dynamics of the coupled ionosphere-magnetosphere system. We study plasma distribution associated with the storm enhanced density (SED) and its counterpart plasmaspheric plume by using a parallel version the new Dynamic Fluid-Kinetic (DyFK) model. In this model multiple drifting individual flux tubes are simultaneously followed for simulating global plasma transport using message passing interface (MPI) library. Within the new DyFK model, a truncated Field Line Interhemispheric Plasma (FLIP) model provides the dynamic ionospheric boundary conditions for the kinetic model at higher altitudes which is based on a generalized semi-kinetic (GSK) simulation code. The McIlwain E5D magnetospheric convection electric potential model with the corotation electric potential is used to calculate the ExB drift in the equatorial for cold ionospheric/plasmaspheric ions. Physical processes that cause plasma redistribution and outflow of multiple ion species (H+/He+/O+) will be quantitatively discussed in our simulation.
