We … Web20 jan. 2024 · A magnetospheric substorm is a major space disturbance that poses several unanswered questions [16,17]. An important feature is the reconfiguration of the magnetic field in the magnetosphere at substorm onset. Prior to its onset, the magnetic field in the near-Earth magnetosphere is stretched considerably along its tail axis.
Web1 feb. 2024 · Auroral beads. Akasofu (1964) identified the auroral counterpart of the magnetospheric substorm. The auroral substorm is the explosive brightening of the most equatorward auroral arc and the rapid poleward expansion of the aurora, corresponding to the reduction of open magnetic flux in the magnetosphere. In figure 2 we show false … Webattention of magnetospheric physicists as regards the varied forms of their occurrence and the physical mechanisms responsible for them, and equally importantly the complex storm-substorm relationship (see, Sharma et al., 2003).
