title = "A Global Magnetohydrodynamic Simulation Study of Ultra-Low
Frequency Waves Activity in the Inner Magnetosphere: Corotating
Interaction Region + Alfv{\'e}nic Fluctuation",
year = "2019",
organization = "AGU Fall Meeting",
abstract = "comprised of a Corotating Interaction Region (CIR) followed by
solar wind Alfv{\'e}nic fluctuations it is not straightforward to
decisively say which solar wind parameters or which combinations
thereof are most effective in causing disturbances in the inner
magnetosphere, or how each part of the complex interplanetary
structure influences the most the temporal evolution of the
magnetosphere. Using global magnetohydrodynamic (MHD) simulations
we perform a study which address some of these questions. Firstly,
we use the magnetic field and plasma parameters of a real
CIR+Alfv{\'e}nic fluctuations event as input to the
SWMF/BATS-R-US code. The model outputs are used to calculate the
convection electric field's power spectral density (PSD)
integrated in the ultra-low frequency (ULF) waves frequency range
in the equatorial, nightside magnetosphere region. Then, we
separate the real event into its constituent parts by building up
synthetic magnetic field and plasma profiles based on the physical
parameters which characterize each of these parts. The MHD code is
then fed with each new synthetic profile containing Alfv{\'e}nic
fluctuations with two driving frequencies, namely 0.833 and 1.66
mHz. Our preliminary results show that the toroidal electric field
(Er) component fluctuations are related with both driving
frequencies, specially at farther out locations near the flanks of
the modeled magnetopause. The poloidal (Ef) component fluctuations
do respond differently to the driving frequencies in terms of both
spatial structure and integrated power intensities.",
