| 内容記述 | Some results of HF Doppler (HFD) measurements using the Communications Research Laboratory HFD network during the large geomagnetic storm of February 6-9, 1986 are reported. In association with the storm sudden commencement at 1312 UT on February 6, HFD frequency deviations belonging to an SCF(+-) type, which is believed to be caused by westward and subsequent eastward electric fields, were observed. Wave parameters of large-scale traveling ionospheric disturbances (period = 80-100 minutes, phase velocity = 440 m/s and horizontal wavelength= 2100- 2600 km) detected on the night of February 7 are almost completely consistent with those observed by the MU radar at Shigaraki. Very clear, sinusoidal HFD oscillations with a period of 2.5 minutes triggered by the sudden impulse at 1748 UT on February 9 were simultaneously accompanied with the geomagnetic pulsation. These HFD oscillations can be explained by the compressions and rarefactions of the ionospheric plasma due to the pulsation magnetic field. | |||||
