Magnetic Energy Storage and the Nightside Magnetosphere–Ionosphere Coupling
The change in the magnetic energy stored in the Earth’s magnetotail as a function of the solar wind IMF conditions are investigated using an empirical magnetic field model. The results are used to calculate the two normal modes contained in the low-dimensional global model called WINDMI for the solar wind driven magnetosphere–ionosphere system. The coupling of the magnetosphere–ionosphere (MI) ...
متن کاملMagnetosphere-Ionosphere Coupling by Alfvén Waves: Beyond Current Continuity
Many numerical models of magnetospheric dynamics treat the ionosphere as an inner boundary condition. These models have traditionally used the current continuity condition, treating the ionosphere as a sheet current in which the electric field is electrostatic. A more general boundary condition is suggested that not only is more complete, but also straightforward to implement. Results from a mo...
متن کاملThe magnetosphere–ionosphere system from the perspective of plasma circulation: A tutorial
This tutorial review examines the role of O in the dynamics of magnetosphere–ionosphere coupling. The life cycle of an O plasma element is considered as it circulates from the midto high-latitude ionosphere. Energization and diversion of the convecting plasma element into outflows involves Alfvénic turbulence at the low-altitude base of the cusp and plasmasheet boundary layer and in downward-cu...
متن کاملOptical and VLF Imaging of Lightning-Ionosphere Interactions
This work addresses some of the key topics of space physics research recommended in the National Research Council 2003 report “A Decadal Research Strategy in Solar and Space Physics”, namely, the thunderstorm-driven electrodynamic coupling between the troposphere, mesosphere, lower ionosphere, and magnetosphere. Lightning-induced electron precipitation encompasses all of these regions, from atm...
متن کاملSaturn: atmosphere, ionosphere, and magnetosphere.
The Cassini spacecraft has been in orbit around Saturn since 30 June 2004, yielding a wealth of data about the Saturn system. This review focuses on the atmosphere and magnetosphere and briefly outlines the state of our knowledge after the Cassini prime mission. The mission has addressed a host of fundamental questions: What processes control the physics, chemistry, and dynamics of the atmosphe...
