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…
Time-scale dependence of solar wind-based regression models of ionospheric electrodynamics
K. M. Laundal, J. P. Reistad, S. M. Hatch +6
The solar wind influence on geospace can be described as the sum of a directly driven component, or dayside reconnection, and an unloading component, associated with the release of…
Separation and Quantification of Ionospheric Convection Sources: 1. A New Technique
J. P. Reistad, K. M. Laundal, N. Østgaard +4
This paper describes a novel technique that allows separation and quantification of different sources of convection in the high-latitude ionosphere. To represent the ionospheric co…
Separation and Quantification of Ionospheric Convection Sources: 2. The Dipole Tilt Angle Influence on Reverse Convection Cells During Northward IMF
J. P. Reistad, K. M. Laundal, N. Østeward +5
This paper investigates the influence of Earth's dipole tilt angle on the reverse convection cells (sometimes referred to as lobe cells) in the Northern Hemisphere ionosphere durin…
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…
Interplanetary Magnetic Field Component Influence on Horizontal and Field-Aligned Currents in the Ionosphere
K. M. Laundal, J. P. Reistad, C. C. Finlay +4
Statistical analyses have shown that the sunward component of the interplanetary magnetic field, (Geocentric Solar Magnetospheric), moderately but significantly af…
