| 英文摘要 | On 3 March 3 2007, five THEMIS satellites on the dusk side of the magnetic layer, three geosynchronous GOES satellites on the downside and morning and ground geomagnetic stations all observed Pc5 ULF waves for almost four hours. We use cross wavelet correlation analysis to calculate the pulse's propagation speed and MVA to determine the propagation direction. Then we combine the speed and the direction to obtain the information of the Pc5 phase velocity vectors. THEMIS satellite observed that Pc5 waves were of compression, propagating sunward at a speed about 6 similar to 20 km/s. Compared to the magnetic layer Alfven speed (1000 km/s), this velocity is relatively low. They may come from the magnetotail or innermagnetosphere instability. Three GOES satellites observed different Pc5 ULF pulsations dominated by the poloidal mode and have the wave packet structure which means that Pc5 waves have the Alfven wave feature, likely originated from K-H instability. The ULF disturbance amplitude observed by ground stations strengthened with increasing latitudes. Pc5 waves reached the highest level at 60 degree latitude. There is good similarity in waveforms between the pulses observed by the Dumont Durville station and the waves observed by THEMIS. |
