Numerical Investigations of Solar Wind-Magnetosphere-Ionosphere Coupling

This project is centered on several problems involving the coupling of mass, momentum, and energy between the solar wind, magnetosphere, and ionosphere. This work involves both the development of new codes and the modification and use of existing codes to address the problem of solar wind-magnetosphere-ionosphere coupling. Specific areas of research during this period include: applying the group’s three-dimensional model for the propagation of compressional and shear Alfvén waves through the auroral ionosphere and atmosphere; applying their code to modeling Alfvén waves in the magnetosphere of Jupiter; investigation of the dynamics of the magnetospheric tail using a three-dimensional version of the total variance diminishing magnetohydrodynamic code developed by the Jones group in the Department of Astronomy; investigating the kinetic dynamics of auroral electrons using a model that describes their trajectories and interactions with kinetic Alfvén waves in the auroral zone in the presence of background parallel electric fields; and developing a model of wave propagation that is appropriate for relevant laboratory experiments, in particular the LAPD experiment at the University of California-Los Angeles.
