Magnetohydrodynamic Modelling of Interplanetary Disturbances Between the Sun and Earth
Author: Murray Dryer
Publisher:
ISBN:
Category : Magnetic storms
Languages : en
Pages : 52
Book Description
A time-dependent, nonplanar, two-dimensional (2-D) magnetohydrodynamic computer simulation model is used to simulate a series of solar flare-generated shock waves and their subsequent disturbances in interplanetary space between the sun and the earth's magnetosphere. The canonical or anzatz series of shock waves include initial velocities near the sun over the range 500 to 3000 km/sec. The ambient solar wind, through which the shocks propagate, is taken to be a steady-state flow that is independent of heliolongitude; its radial dependency consists of a representative set of plasma and magnetic field parameters which will be presented. Particular attention is directed to the MHD model's ability to address fundamental operational questions regarding the long-range forecasting of geomagnetic disturbances. These questions are: (1) will a disturbance (such as the present canonical series of solar flare shock waves) produce a magnetospheric and ionospheric disturbance, and, if so; (2) when wil it start; (3) how severe will it be; and (4) how long will it last? The model's output is used to compute various solar wind indices of current interest for this purpose. It is concluded that future work should be focused on a cohesive updating of, for example, daily measured solar parameters as input for the model whose output should be compared with spacecraft data for specific events.

Book Description
These proceedings contain the review and contributed papers given at the SMY--SMA Workshop held in Irkutsk (USSR), 17--24 June 1985. The main themes of the Workshop were plasma physics and magnetohydrodynamics with applications to processes occurring in solar flares. The papers published in this volume are organized around the following topics: -- the reconnection of coronal magnetic fields as a source of flare energy -- the acceleration of particles to high energies -- the dynamics of interplanetary clouds and shocks

Space Weather Monitoring by Ground-Based Means
Author: Oleg Troshichev
Publisher: Springer Science & Business Media
ISBN: 3642168035
Category : Medical
Languages : en
Pages : 305
Book Description
This book demonstrates that the method, based on the ground polar cap magnetic observations is a reliable diagnosis of the solar wind energy coming into the magnetosphere Method for the uninterruptive monitoring of the magnetosphere state (i.e. space weather). It shows that the solar wind energy pumping power, can be described by the PC growth rate, thus, the magnetospheric substorms features are predetermined by the PC dynamics. Furthermore, it goes on to show that the beginning and ending of magnetic storms is predictable. The magnetic storm start only if the solar energy input into the magnetosphere exceeds a certain level and stops when the energy input turns out to be below this level.
