abstract = "The interaction and response of the magnetic cloud-type structure
with Earth's magnetosphere were modeled by the SWMF/BATS-R-US
code. The conversion of magnetic (E-m), kinetic (E-k), and
internal (E-i) energies was analyzed as well as the wave power
integrated in the ultra-low frequency (ULF) range of the poloidal
(E-phi) and toroidal (E-r) electric field components in the
equatorial region of the magnetosphere, in seven 2-hr long
intervals, namely, I1 through I7. The intensity of energy
conversion and wave activity for I1 and I7 intervals was
negligible. The energy conversion started in the I2 interval and
extended to the I3, I4, and I5 intervals. The power of the E-phi
and E-r components in the dayside and nightside regions is clearly
observed. The I4 corresponds to interplanetary magnetic field
(IMF) B-z mostly southward and the I5 has similar amplitudes of
the B-z and B-y components, corresponding to the period of the
high geomagnetic activity. The conversion rate for the I4 and I5
was similar, however, the integrated power spectral density (IPSD)
of the E-phi and E-r components is more intense in I5. During the
I6 interval, with predominant IMF B-y, the energy conversion rate
is intensified mostly for inner radial distances R R-E, and the
E-k component becomes close to zero for outer regions. The energy
conversion regions are located spatially close to or overlapping
with regions where the IPSD in the ULF range is intensified. The
energy conversion in the inner magnetosphere occurred
preferentially between E-m and E-i, with the E-k energy component
always present but with lower intensities.",
