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…

Dayside and nightside magnetic field responses at 780 km altitude to dayside reconnection

K. Snekvik, N. Østgaard, P. Tenfjord +4

During southward interplanetary magnetic field, dayside reconnection will drive the Dungey cycle in the magnetosphere, which is manifested as a two-cell convection pattern in the i…

North-south asymmetries in cold plasma density in the magnetotail lobes: Cluster observations

S. Haaland, B. Lybekk, L. Maes +7

In this paper, we present observations of cold (0-70 eV) plasma density in the magnetotail lobes. The observations and results are based on 16 years of Cluster observation of space…

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…
