Abstract

We use five years of Geotail and AMPTE/IRM measurements in the near-Earth magnetotail to compute angles between vectors of fast earthward plasma flowand the local magnetic field. In the low-beta parts of the magnetotail, fast flows were found to be nearly field-aligned with an average angle of similar to 20 degrees. In the high-beta plasma sheet the average angle was larger than 45 degrees. The existence of a substantial convective component inthe plasma sheet confirms the importance of the bursty bulk flow phenomenon for the magnetotail convection process.
