Roles of Magnetospheric Convection on Nonlinear Drift Resonance Between Electrons and ULF Waves
Journal of Geophysical Research: Space Physics, 2020In the Earth's inner magnetosphere, charged particles can be accelerated and transported by ultralow frequency (ULF) waves via drift resonance. We investigate the effects of magnetospheric convection on the nonlinear drift resonance process, which ...

ULF wave observations in Jupiter's magnetosphere
Advances in Space Research, 2001In previous work we have examined magnetometer data from the Ulysses Jupiter flyby, and in particular middle magnetosphere observations in the vicinity of the magnetodisk. Waves transverse to the background magnetic field were found in the heavy ion gyrofrequency regime, a signature of Ion Cyclotron (IC) waves. We examined the dayside and high latitude

Interaction of the solar ULF waves with the magnetosphere
AIP Conference Proceedings, 2007We present preliminary results of global simulations of the magnetosphere‐ionosphere system to investigate how the solar wind and the interplanetary magnetic field couple ULF wave energy into the magnetosphere, which waves are most geo‐effective and how the orientation influences the energy path down to the ionosphere. While more detailed investigation

Magnetospheric ULF Waves: A Review
2011Ultra-low frequency (ULF; approx. 1 mHz ≤ f ≤ 10 Hz) MHD plasma waves are readily recorded throughout the Earth’s magnetosphere and on the ground. Generated by a variety of instabilities, ULF waves transport and couple energy throughout the system, and may play important roles in the energization and loss of radiation belt particles.

ULF waves at very high latitudes
2006Observations in the ULF frequency range (from mHz to Hz) at very high latitudes, at the poleward auroral boundary and beyond, make it possible to characterize the turbulent energy transfer from the solar wind into dayside regions of the magnetosphere and the magnetotail.

The field of ultra-low frequency (ULF) wave research is an important piece in the jigsaw of the dynamics of the Earth's magnetospheric system. These waves are recognized through their interactions with particles and fields, and energy transfer processes.

Excitation of ULF and VLF waves in the ionosphere
Planetary and Space Science, 1980Abstract It is shown that a two-dimensional lower-hybrid wave structure can parametrically trigger the growth of VLF and ULF noises in a plasma. Analytical expressions for the increment and threshold of the instability are obtained. Application of our work to the auroral zones of the topside ionosphere is discussed.

Theory of ULF-modulated electrostatic wave
Planetary and Space Science, 1986Abstract Generation mechanism of ELF emissions in the presence of a coherent ULF wave based on the plasma maser theory is proposed. The results are consistent with the observation by Cornilleau-Wehrlin (1981).

The behaviour of ulf waves and particles in the magnetosphere
Planetary and Space Science, 1973Abstract A general study is made of the effect of low frequency waves in the magnetosphere on the adiabatic motion of particles. Previous ideas about the behaviour of resonant particles are confirmed and it is concluded that the transverse mode is generally likely to be most easily generated by bounce resonance in the magnetosphere.

ULF waves and the ground magnetic field
Journal of Geophysical Research: Space Physics, 1998A theory is put forward to account for the horizontal structure and polarization of the magnetic field of low‐frequency ULF waves on the ground at low latitudes. The theory is based on the condition that the component of the rotation of magnetic field normal to the Earth's surface vanishes in the neutral atmosphere and also on an assumption that the ...
