Scientific paper

The bursty bulk flows (BBFs) are known to have abrupt increases of the plasma flow velocity and the intensity of the northward/southward magnetic fields, occasionally followed by periodic variations with 1-3 minute characteristic time. In this paper, a theoretical model for the BBFs is proposed. In our model, a region of dawnward electric field is assumed to propagate earthward , which corresponds to the propagation of the fast-mode wave front generated by magnetic reconnection. The coupling between the magnetosphere and the ionosphere is modeled by means of an equivalent electric circuit. We made a series of test particle simulations with an assumption that each test particle corresponds to a magnetic flux tube. We further obtained an analytic solution that approximates the numerical results and suitably explains the main characteristics of actual BBFs.
