High-latitude cold ion outflow inferred from the Cluster wake observations in the magnetotail lobes and the polar cap region
Li, Kun; André, Mats; Eriksson, Anders; Wei, Yong; Cui, Jun; Håland, Stein Egil (Journal article; Peer reviewed, 2021)Cold ions with low (a few eV) thermal energies and also often low bulk drift energies, dominate the ion population in the Earth’s magnetosphere. These ions mainly originate from the ionosphere. Here we concentrate on cold ... -
A New Concept to Measure the Ambipolar Electric Field Driving Ionospheric Outflow
Li, Kun; Håland, Stein Egil; Wei, Yong (Journal article; Peer reviewed, 2021)Over the last few decades, the role of ionospheric outflow for the loss of atmospheric constituents, as a plasma supplier to the magnetosphere and hence for the evolution of the Earth’s atmosphere has been recognized. A ... -
The Polar Wind Modulated by the Spatial Inhomogeneity of the Strength of the Earth's Magnetic Field
Li, Kun; Förster, Matthias; Rong, Zhaojin; Haaland, Stein; Kronberg, E.; Cui, Jun; Chai, Lihui; Wei, Yong (Journal article; Peer reviewed, 2020)When the geomagnetic field is weak, the small mirror force allows precipitating charged particles to deposit energy in the ionosphere. This leads to an increase in ionospheric outflow from the Earth's polar cap region, but ...
