PROBLEMS OF GEOCOSMOS

Proceedings of the 7th International Conference "Problems of Geocosmos" (St. Petersburg, Russia, 26-30 May 2008)
have considered in [Sedykh, Ponomarev, 2002; Sedykh et al., 2004] the important but particular case of the
ionosphere-magnetosphere coupling in the region of auroral electrojets.
Conclusions
We managed to generally describe magnetospheric processes and phenomena since used the new
constructive conception based on the C.F. Kennel assumption [Kennel, 1969] that pitch-angle diffusion of
electrons and protons and convection of plasma are the main processes of magnetospheric physics.

Figure 7. The simplified scheme of the structurally adequate model of magnetospheric processes.
Apart from its cognitive value, the model (fig. 7) will be useful for predicting the response of the
magnetosphere to extreme situations absent from the teaching sample of empiric models, as well as for
compatibility between various empiric models predicting magnetospheric disturbances and determination of
the limits of their applicability.
