Sažetak
The novel missions, IMAGE, CLUSTER, and THEMIS have given a new insight into the plasmaspheric dynamics and have revealed different unexpected plasmapause structures (e.g., plumes, notches, and shoulders) that are mainly formed during the periods of enhanced geomagnetic activities. Generally, great progress has been made in understanding the plasmaspheric dynamic and plasmapause structure formation. Nevertheless, the basic questions related to the global plasmapause behavior, as MLT of the plasmapause formation and propagation characteristics of the main plasmapause have still remained unclear. By applying the cross-correlation analysis to the plasmapause databases based on CLUSTER, CRRES and THEMIS satellites, and both solar wind parameters and geomagnetic indices we derived the most important physical effects on plasmapause formation and propagation. The derived plasmapause characteristics are compared with the numerical simulations based on interchange instability mechanism. The obtained results will be discussed and the implication for space weather will be emphasized.
