Observations of Asymmetric Lobe Convection for Weak and Strong Tail Activity
A. Ohma, N. Østgaard, J. P. Reistad +6
In this study we use high-quality convection data from the Electron Drift Instrument on board Cluster to investigate how near-Earth tail activity affects the average convection pat…
Characteristics of the Flank Magnetopause: THEMIS Observations
S. Haaland, A. Runov, A. Artemyev +1
The terrestrial magnetopause is the boundary that shields the Earth's magnetosphere on one side from the shocked solar wind and its embedded interplanetary magnetic field on the ot…
How the IMF Induces a Local Component During Northward IMF and Characteristic Timescales
P. Tenfjord, N. Østgaard, S. Haaland +7
We use the Lyon-Fedder-Mobarry global magnetohydrodynamics model to study the effects of the interplanetary magnetic field (IMF) component on the coupling between…
Observations of Asymmetries in Ionospheric Return Flow During Different Levels of Geomagnetic Activity
J. P. Reistad, N. Østgaard, K. M. Laundal +7
It is known that the magnetic field of the Earth's closed magnetosphere can be highly displaced from the quiet-day configuration when interacting with the interplanetary magnetic f…
Birkeland current effects on high-latitude groundmagnetic field perturbations
K. M. Laundal, S. E. Haaland, N. Lehtinen +8
Magnetic perturbations on ground at high latitudes are directly associated only with the divergence-free component of the height-integrated horizontal ionospheric current, $\textbf…
How the IMF induces a component in the closed magnetosphere and how it leads to asymmetric currents and convection patterns in the two hemispheres
P. Tenfjord, N. Østgaard, K. Snekvik +4
We used the Lyon-Fedder-Mobarry global magnetohydrodynamics model to study the effects of the interplanetary magnetic field (IMF) IMF component on the coupling bet…
