  • Disturbances in the magnetosphere
    (Lecturer: Victor A. Sergeev)
    Theoretical models, observations and simulation results are combined to form a coherent picture of particle acceleration and energy transformation in the open convecting magnetosphere. Different aspects of internal magnetospheric dynamics including explosive energy dissipation events (substorms) as well as the convection `crisis problem are specifically addressed. Generation of field aligned currents and field-aligned acceleration in the 3-dimensional current system are described as basic phenomena in magnetospheric-ionospheric coupling.

Acceleration of electrons in the double layers potential regions. Development of substorm in polar aurora and in the magnetosphere's tail.

  • Physics of the highlatitude ionosphere
    (Lecturer: Andrey L. Kotikov)
    Problems of the physics and morphology of the highlatitude ionosphere are considered. The distribution of the different types of the layers in E region, ionic composition, the features of the auroral sporadic layer are explained as a result of the layer formation mechanisms . The association with the auroral particle precipitation zones are considered. The physics of the structure of the highlatitude layer F2 is studied. The convection of the ionospheric plasma, the drag of the neutral component, gravitatic waves are considered. By the consideration of the physics - chemical processes in D region the most attention are devoted to the auroral absorption, the absorption in the polar cap, the storm in the absorption and the riometer measurements. The charge particle diffusion in anisotropic gyrotropic plasma is studied. The evolution of the plasma instabilities is investigated.

  • Magnetic reconnections
    (Lecturer: Vladimir S. Semenov)
    The problem of rapid conversion of magnetic energy into plasma energy is considered in details including (i) usual Ohm dissipation; (ii) tearing-instability; (iii) Petschek-type reconnection. The importance of this process is illustrated on the examples of solar flares, magnetospheric substorms, flux transfer events (FTEs) at the dayside magnetopause and others.

  • Non-linear problems of magnetohydrodynamics
    (Lecturer: Vladimir S. Semenov)
    In the space magnetic fields and plasma are strongly coupled, and therefore very often magnetic flux tubes can be considered as non-linear MHD-strings. A special method based on introduction so-called frozen-in coordinate system is considered in details with application to the "load"-"unload" processes in cosmic plasma.
