Magnetospheric substorms encompass a myriad of dynamical phenomena resulting from the coupling of the solar wind with the Earth’s magnetic field and the ionosphere. Although external solar wind conditions conducive to substorm development are generally regarded as identified, the precise cause for substorm onset remains an outstanding unresolved ...

Do events in the solar wind “trigger” substorms, or do substorms occur independently? Is there a difference between triggered and untriggered substorms? What kinds of events trigger onsets? Expansions? Can we learn about their physics from the things that do and do not trigger them?

A magnetospheric substorm is a transient process initiated on the night side of the earth, in which a significant amount of energy derived from the solar wind‐magnetosphere interaction is deposited in the auroral ionosphere and magnetosphere. Substorms are controlled by the interplanetary magnetic field, ceasing when it points northward for long ...

Multiple substorm injections and the new substorm paradigm: Interpretation of the CDAW 7 substorm
Advances in Space Research, 1993Abstract In the near-Earth neutral line model, the substorm is triggered by reconnection in the magnetotail and its effects radiate from there. In recent years new observations have suggested a new paradigm for substorms in which there are two coupled acceleration regions.

The recovery phase of the magnetospheric substorm is studied numerically by means of a two-dimensional time-dependent nonlinear resistive MHD code. The initial configuration was chosen from the earlier numerical model in which the magnetospheric substorm was driven by the solar wind plasmas. In order to study the recovery phase, the entering solar wind

We show that during magnetospheric substorms there is a clear tendency for the westward electrojet current to follow a characteristic curve that can be matched with an exponential equation. The substorm recovery phase has a characteristic timescale, or exponential time constant, that does not vary substantially from one substorm to the next. There is a

The mechanisms by which substorms are generated are still a subject of considerable controversy. A brief review of the historical development of some of the concepts of substorm generation, and the relative merits of these concepts, are discussed against the background of the large number of observational data now available.

Around the time the steady convection model was being developed, Akasofu (1964) was arranging ground-based magnetometer and all-sky camera observations of the complex time dependence of nightside auroral activity into the central phenomenological conception of tune-dependent magnetospheric physics—the auroral substorm.

Watts (1957) and Ellis (1957, 1959) were among the first to recognize atmospheric radio noise at kilocycle frequencies, which is closely associated with strong auroral and magnetic activity. Ellis (1959) showed that noise appears as bursts and that some of the bursts were well correlated with an enhancement of the red oxygen line (λ 6300) in airglow ...
