Modulation of dayside reconnection during northward interplanetary magnetic field
[1] On 17 September 2000 the IMF was directed continuously northward for more than 3 hours. Density fluctuations in the solar wind resulted in quasiperiodic variations in the solar wind dynamic pressure, and correlated fluctuations also occurred in the IMF Bz component. The Northern Hemisphere SuperDARN radars observed bursts of highlatitude high-velocity plasma flow during this northward IMF i...
متن کاملOn the triggering of auroral substorms by northward turnings of the interplanetary magnetic field
Some studies over the last decade have indicated that the instability responsible for substorm expansion phase onset may require an external trigger such as a northward turning of the interplanetary magnetic field (IMF). Statistical investigations have lead to contrasting interpretations regarding the relationship between proposed solar wind triggers and substorm onsets identified from geomagne...
متن کاملFilamentary field-aligned currents at the polar cap region during northward interplanetary magnetic field derived with the Swarm constellation
ESA's Swarm constellation mission makes it possible for the first time to determine field-aligned currents (FACs) in the ionosphere uniquely. In particular at high latitudes, the dual-satellite approach can reliably detect some FAC structures which are missed by the traditional single-satellite technique. These FAC events occur preferentially poleward of the auroral oval and during times of nor...
متن کاملNeutral Motions in the Polar Thermosphere for Northward Interplanetary Magnetic Field
On 24th November, 1982, The North-South (Bz) component of the Interplanetary Magnetic Field (IMF) became positive for a period of about 11 hours reaching a relatively large and steady value of---25 nT. During this rare occurrence, the Dynamics Explorer-2 (DE-2) spacecraft was in a configuration that enabled the dynamics of both ionic and neutral species of the high-latitude F-region to be measu...
متن کاملTransient changes in magnetospheric‐ionospheric currents caused by the passage of an interplanetary shock: Northward interplanetary magnetic field case
[1] We use results from a global MHD simulation to study the interaction of an interplanetary shock with the Earth’s magnetosphere for a northward interplanetary magnetic field orientation. We connect intensifications of the transient northward Bz (NBZ) and Region 1 currents in the ionosphere with the appearance of two strong dynamo regions in the magnetosphere: the first on the high‐latitude m...
