摘要：
Analysis of data from an oblique HF phase path sounder deployed on sub-Antarctic Macquarie Island revealed quasi-periodic variations in the amplitude and change in phase path of the daytime radio echo when a travelling ionospheric disturbance (TID) was present at the point of reflection. The daytime amplitude records exhibit signatures of TIDs with a cut-off period at 23 min, whereas signatures appear in the daytime change in phase path records for TID periods up to 65 min. This phenomenon was investigated using ray-tracing analysis.
