Two spacecraft observation of plasma sheet convection jet during continuous external driving

説明
<jats:p>During ∼18 hours of continuous activity caused by long interval of southward IMF, the INTERBALL/Tail Probe and GEOTAIL spacecraft monitored the plasma sheet in dusk and dawn sectors of the midtail plasma sheet at 25–30 <jats:italic>R<jats:sub>E</jats:sub></jats:italic>. While bursty bulk flows were persistently observed at both spacecraft, there was a systematic difference between the hourly averages of the Earthward flux transport. During a 3‐hour interval the average flux transport rate (<jats:italic>E<jats:sub>y</jats:sub></jats:italic>) on GEOTAIL (dawn plasma sheet) was ∼3 times larger than both the average <jats:italic>E<jats:sub>y</jats:sub></jats:italic> on INTERBALL (dusk plasma sheet), and the cross‐tail <jats:italic>E<jats:sub>y0</jats:sub></jats:italic> expected for the existing IMF conditions. This implies that the most intense bursty bulk flows tend to be confined within a limited longitudinal sector of the magnetotail (<jats:italic>X</jats:italic> < −30 <jats:italic>R<jats:sub>E</jats:sub></jats:italic>) forming the observed average convection jet feature.</jats:p>
