Speed of Magnetopause Motion: A New Hypothesis for Using Ion Speed
Original language description
The magnetopause is the critical boundary where the shocked solar wind fromthe Sun meets the Earth's magnetic field. Once the upstream solar wind conditions alter,the magnetopause moves to (and oscillates about) a new position and changes its shapeaccordingly. Previous studies usually calculated the magnetopause moving speed fromspatial and temporal differences of two crossings close in location and time observed bytwo spacecraft. However, based on observations, a magnetopause boundary layer witha thickness of hundreds of km is often observed. We propose a new way of estimatingmagnetopause speed by applying the ion speed in the boundary layer. This study aims tocheck whether our idea is correct by using numerous magnetopause crossings recorded bythe THEMIS mission, and the magnetopause speed calculated by the traditional method iscompared with the mean velocity inside the boundary layer.
