Analytical study of the energy rate balance equation for the magnetospheric storm - ring current
We present some results of the analytical integration of the energy rate balance equation, assuming that the input energy rate is proportional to the azimuthal interplanetary electric ®eld, Ey , and can be described by simple rectangular or triangular functions, as approximations to the frequently observed shapes of Ey , especially during the passage of magnetic clouds. The input function is al...
متن کاملEnergetic ion injection and formation of the storm-time symmetric ring current
An extensive study of ring current injection and intensification of the storm-time ring current is conducted with three-dimensional (3-D) test particle trajectory calculations (TPTCs). The TPTCs reveal more accurately the process of ring current injection, with the main results being the following: (1) an intense convection electric field can effectively energize and inject plasma sheet particl...
متن کاملEffect of solar wind pressure enhancements on storm time ring current asymmetry
[1] The effect of solar wind pressure enhancements on storm time ring current asymmetry is investigated by examining the asymmetric variations in the north-south (H) and east-west (D) components of the geomagnetic field during four magnetic storms. For two strong storms, on 25 September 1998 and 29 May 2003, pressure enhancements occurred during the main phase with strong and steadily southward...
متن کاملRelative contribution of electrons to the stormtime total ring current energy content
[1] We evaluate the relative importance of stormtime ring current electrons to protons by calculating the energy content ratio of electrons to protons for typical ring current energies inferred from observations and simulations. We analyze Explorer 45 measurements taken around the minimum Dst(= 171 nT) of the 17 December 1971 storm. We simulate the electron and proton ring current energy conten...
