Magnetospheric substorm activity is presently understood as the combined effect of energy transport and dissipation which is directly driven through the solar-terrestrial interaction and of the unloading of energy stored in the magnetotail. Many studies of particle and field signatures of substorms in the magnetotail have led to the proposal that a neutral line forms close to the Earth at the time of expansive phase onset with the plasma sheet population on the anti-Earthward side of the neutral line ultimately being lost to the solar wind through the ejection of the plasmoid. While the near-Earth neutral line model has provided a useful working model for substorm phenomenology, it is not a unique description for understanding the observations.
