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 کاملGeomagnetic transport in the solar wind driven nightside magnetosphere–ionosphere system
A spatially resolved nonlinear dynamical model of the solar wind driven geomagnetic tail plasma is developed for the purpose of space weather predictions. The model represents the fluctuating electromagnetic fields and high pressure central plasma sheet by a large number (2N&200) of semiglobal coupled current loops ranging from the near-Earth geosynchronous orbit position for substorm dynamics ...
متن کاملMultiple discrete - energy ion features in the inner magnetosphere : 9 February 1998 , event
Multiple discrete-energy ion bands observed by the Polar satellite in the inner magnetosphere on 9 February 1998 were investigated by means of particle simulation with a realistic model of the convection electric field. The multiple bands appeared in the energy vs. L spectrum in the 1–100 keV range when Polar traveled in the heart of the ring current along the outbound and inbound paths. We per...
متن کاملEffect of storm-time plasma pressure on the magnetic field in the inner magnetosphere
[1] We investigate the effect of plasma pressure on the magnetic field in the near-Earth magnetosphere (2 to 6.5 RE) during the major magnetic storm of October 21–25, 2001. For this we obtain a time series of ‘‘snapshots’’, in each of which the magnetic forces are equilibrated by plasma pressure gradient forces. Each snapshot is computed using our 3-D equilibrium code, which is fed anisotropic ...
متن کاملDiscovery of nitrogen in Saturn’s inner magnetosphere
[1] We detected N in Saturn’s magnetosphere in the range L 3.5 to 9.5 Saturn Radii (Rs) using data collected by the Cassini Plasma Spectrometer during Saturn Orbit Insertion and the following orbit (Rev A). The presence of N in Saturn’s magnetosphere has been a source of much debate since Voyager’s detection of unresolved mass/charge 14–16 amu ions in this region. Two principal nitrogen sources...
