[1] In this study we present the first results from the University of Michigan’s coupled magnetosphere-ionosphere-thermosphere general circulation model. This code is a combination of the Michigan MHD model with the NCAR thermosphere-ionosphereelectrodynamics general circulation model (TIEGCM). The MHD code provides specification of the high-latitude ionospheric electric potential and the parti...

The dissipation power and size of auroral blobs are investigated in detail to examine the possible analogy between the dynamic magnetosphere and a forced and/or selforganized critical system. The distributions of these auroral parameters are sorted in terms of different levels of activity, namely substorms, pseudo-breakups, and quiet conditions. A power law (scale-free) component is seen in all...

Violation of the axial symmetry of a magnetic field essentially modifies the physics of the plasma outflow in the magnetosphere of rotating objects. In comparison to the axisymmetric outflow, two new effects appear: more efficient magnetocentrifugal acceleration of the plasma along particular field lines and generation of MHD waves. Here, we use an ideal MHD approximation to study the dynamics ...

Interactions during Substorms (THEMIS), and Cluster now enable comprehensive systematic studies 13 to address these questions in a better way. Therefore, this special issue "Magnetosphere IonosphereResponse the Solar Wind Transients" aims of integrating various pertaining response 15 magnetosphere ionosphere transient solar wind structures get an improved perspective 16 basic underlying physica...
