Investigations of ionospheric E-region field-aligned irregularities observed with Kunming VHF radar
The statistical characteristics of mid-low latitude ionospheric E-region field-aligned irregularities(FAI)observed with the Kunming very high-frequency(VHF)radar are presented.First,the observational results show that the irregularities appeared mainly in periods before noon and near night,with the nighttime echoes being more intense and covering a greater height extent than that during the daytime.Second,we observed the existence of two well-defined types of echoes in the nighttime: the lower E-region echoes(115-130km)and upper E-region echoes(130-150km).Moreover,there are differences in FAIs motion characteristics at different range in the daytime and nighttime.Without in-field measurements,it is difficult to verify what physical mechanisms may explain the formation of the irregularities,which we will combine other facilities to analyze it in the future.
