A new diffusion matrix for whistler mode chorus waves
Meredith, Nigel P.; Horne, Richard B.; Glauert, Sarah A. +5 more
Global models of the Van Allen radiation belts usually include resonant wave-particle interactions as a diffusion process, but there is a large uncertainty over the diffusion rates. Here we present a new diffusion matrix for whistler mode chorus waves that can be used in such models. Data from seven satellites are used to construct 3536 power spec…
Generation of Pi2 pulsations by intermittent earthward propagating dipolarization fronts: An MHD case study
El-Alaoui, M.; Walker, R. J.; Goldstein, M. L. +3 more
Using a global magnetohydrodynamic (MHD) simulation of the magnetosphere during a disturbed interval on 14 September 2004, we have investigated fluctuations in plasma properties of the magnetotail in the Pi2 range and their relationship to dipolarization fronts (DFs). Results from the MHD simulation indicate that this event is a very active interv…
