Websatellites we report on the statistical properties of bursty bulk flow events (BBFs) in the inner plasma sheet (IPS). A positive correlation between BBFs and the AE index suggests that BBFs are predominantly geomagnetically active time phenomena. Earthward BBFs are more frequent close to midnight and away from Earth, up to a distance of ~19 RE. WebJun 1, 2024 · Abstract. Using a global magnetospheric MHD model coupled with a kinetic ring current model, we investigate the effects of …

They found a link ... WebBursty Bulk Flow (BBF) events are an important means of plasma transport in the Earth's magnetotail during substorms. While several studies have been performed using in-situ plasma and field data to determine the characteristics of BBFs, remarkably little attention has been paid to the question of whether or not these events also manifest themselves in …
WebFeb 1, 2024 · In particular, we investigate bursty bulk flow driven multi-scale transfer of energy towards the dissipation scale, and provide evidence for the presence of non-linear interactions. We show that, in contrast with previous results, Alfvénic fluctuations together with 2D eddy interactions may appear as important constituents of turbulence in the ...
