Заглавие: Dynamics of the Field-Aligned Current Systems Observed during The Super-Storm on Nov. 20, 2003

Количество страниц: 4 с.

Spatial distribution in the polar ionosphere of field-aligned currents density is studied by using data of the events on 20.11.03. Observable distributions are described in terms of three Regions of Iijima and Potemra, with taken into account in each Region of three types of spatial inhomogeneities. These inhomogeneitie were overlooked earlier. Dynamics of classical substorm current wedge SCW1, and the "current wedges" SCW2 and SCW3, both creating a polarization and amplification of the westward auroral electrojet, are described.

Заглавие: Dynamics of the Ionospheric Convection Systems Observed during The Super-Storm on Nov. 20, 2003

Количество страниц: 3 с.

In the accompanying Papers 1 and 2 was fulfilled timing of the 20.11.05 super-storm. Were detected 4 various types of the magnetospheric disturbances observable at southward IMF, and presented a new model of the field-aligned currents density spatial distribution in the polar ionosphere. In this paper are described the ionospheric convection systems, characteristic for the above various types. Are mentioned the mesoscale spatial inhomogeneities, which are observed more or less regularly but have not been mentioned in the past literature.

Заглавие: Effect of Bγ IMF in substorm current wedge formation

Количество страниц: 4 с.

Based on the data of longitudinal chain of midlatitude stations in the northern hemisphere, substorm-associated field-alighned currents (FACs) are examined. A comparison of IMF component variations with surface FAC characteristics in substorm sites is performed. It is shown that the ratio between the upward and downward surface FAC intensities depends on By IMF. In this regard, the conditions are discussed that favor currents flowing from the dayside cusp to nightside auroral region. These currents, which position is dependent on By IMF direction, can be responsible for difference between the upward and downward current-wedge-associated FACs.

Заглавие: Evolution of negative SI-induced ionospheric flows observed by SuperDARN King Salmon HF radar

Количество страниц: 14 с.

The spatial evolution of vortex-like flow structures induced by a negative sudden impulse (SI-) is studied on the basis of SuperDARN King Salmon HF radar (KSR) with other ground and satellite data. A large dip in the solar wind density induced a fairly large SI- with a SYM-H amplitude of ~40 nT. The SI-induced ionospheric flow signatures in the evening sector (MLT ~ 19 h) were observed by KSR as a westward flow associated with the preliminary impulse (PI) followed by a more intense eastward flow with the main impulse (MI) in the sub-auroral region on the magnetic latitude ~60-70 deg, consistent with the local ground magnetic field observations. Following the first PI-MI flow sequence, KSR saw a second and possibly third sequence of flow variation which were much smaller in flow amplitude than the first pair but showed qualitatively very similar flow variations and latitudinal/longitudinal propagation characterististics/ These observations can be interpreted as aftershocks of the first PI-MI; the same sequence of vortices and field-aligned currents were generated and then drifted anti-sunward with the same mechanism, namely the pumping motion of dayside magnetosphere. These results are qualitatively consistent with predictions suggested by recent numerical simulations.
