Abstract
On April 15th 2003, Cluster crossed the dayside magnetopause boundary and observed a series flux transfer events (FTEs) during the interval from 0630 to 0730 UT. During this period, the interplanetary magnetic field (IMF) showed a negative z component and a positive y component. Simultaneous corresponding transient plasma flows were identified in the near-conjugate polar ionosphere by the CUTLASS Finland HF radar, and the geomagnetic field disturbances were observed by the IMAGE ground-based magnetometers. By combing these data and applying the Cooling model, we show that the transient plasma flows and the geomagnetic field disturbances are closely related to the dayside FTEs.
