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 کاملInterhemispheric observations of the ionospheric signature of tail reconnection during IMF-northward non-substorm intervals
This paper presents the first interhemispheric radar observations interpreted as the ionospheric response to tail reconnection during IMF-northward non-substorm intervals. SuperDARN measurements of plasma convection in the nightside ionospheres of both hemispheres, taken on 21–22 February and 26–27 April 2000, show bursts of flow in the midnight sector which are understood to be characteristic ...
متن کامل2D plasma sheet ion density and temperature profiles for northward and southward IMF
[1] We previously developed a method for inferring plasma sheet ion temperature and density from ionospheric observations. Using this method and DMSP observations for 1992, we present 2D profiles of the equatorial plasma sheet ion density and temperature for southward and northward IMF for b2i > 64 or Kp < 3. During periods of northward IMF, cold dense ions can be found plentifully along the pl...
متن کاملAsymmetry of the ion diffusion region Hall electric and magnetic fields during guide field reconnection: observations and comparison with simulations.
In situ measurements of magnetic reconnection in the Earth's magnetotail are presented showing that even a moderate guide field (20% of the reconnecting field) considerably distorts ion diffusion region structure. The Hall magnetic and electric fields are asymmetric and shunted away from the current sheet; an appropriately scaled particle-in-cell simulation is found to be in excellent agreement...
متن کاملComparative analysis of dayside magnetic reconnection models in global magnetosphere simulations
We test and compare a number of existing models predicting the location of magnetic reconnection at Earth’s dayside magnetopause for various solar wind conditions. We employ robust image processing techniques to determine the locations where each model predicts reconnection to occur. The predictions are then compared to the magnetic separators, the magnetic field lines separating different magn...
