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…

X-ray Emissions in a Multiscale Fluid Model of a Streamer Discharge
Nikolai G. Lehtinen, Nikolai Østgaard
We use a three-specie fluid model of electric discharge in air to simulate streamer evolution from the avalanche-to-streamer transition to the collision of opposite-polarity stream…
