AORTA

The Auroral Electrojetsosphere. These current systems permit energy imparted to the convective motion of magnetospheric plasma to be dissipated in the ionosphere through the process of Joule heating. In this paper we shall review the various component three-dimensional current systems which relate to the electrojets and w

Studies of Currents and Electric Fields in the Auroral Zone Ionosphere using Radar Auroral Backscattffects of the two-stream and gradient-drift plasma instabilities. These instabilities require relative streaming of the electrons and ions. Measurements at VHF frequencies have shown that the instabilities generally are excited when the streaming velocity is in excess of 300 to 400 m/s. At UHF frequ

Electric Fields and Currents in the Earth’s Magnetosphere The main results of calculations include the well-known patterns of space distribution E. and j. j., based on the satellite measurements (OGO-5,6, TRIAD),etc) and, besides, some essential additions. For example, ionospheric projection of the magnetospheric cleft (of polar cap boundary) or the outer

Magnetic Substorm Characteristics Described by Magnetic Potential Maps for 26 – 28 March 1976 from 52 northern hemisphere observatories are used to create magnetic potential contour plots representing so called “equivalent ionospheric current” systems. Contour plots of 10 isolated and storm-time substorms for 26 – 28 March 1976 demonstrate the dynamic behavior of the westward and eastward e

Macroinstabilities of the Magnetotaille process is an instability of the magnetotail. The stability theory of the tail is summarized and the major predictions are described. It is argued that the spontaneous reconnection (tearing) picture is consistent with observations made in the magnetotail. In particular, it can explain field-align

Substorms and Magnetospheric Energy Transfer Processes This is in contrast to the widely accepted premise that solar wind energy is accumulated in the magnetosphere and then released by an instability process occurring in the magnetotail. It is shown that much of the plasma sheet behavior associated with auroral substorms can be interpreted in terms of

Drawing with Vertices and Matriceson that the process of reconnection is occurring. However, it does not elucidate the physical mechanisms by which such reconnection occurs. The study of the physical processes at the magnetopause and their control by the IMF is actively being investigated on the ISEE mission. Initial results indicat
