AbstractThe ionospheric spread-F has many significant effects on radio waves that propagation through the Earth's atmosphere, such as refraction, reflection, absorption, time delay, phase change, amplitude change, Doppler shifts, and so on. In this paper, we used the data from DPS-4 Digisondes at low latitude station Hainan (19.4 degrees N, 109.0 degrees E), China, and high altitude stations Yakutsk (62 degrees N, 129 degrees E) and Zhigansk (66 degrees N, 123 degrees E), Russia to study the ionospheric Spread-F (SF) properties during geo-magnetic storm time. Some new results are obtained by data analysis. In Hainan and Yakutsk, SF was observed only in night time, but in Zhigansk it was also observed in day time. The SF seems more activity over Yakutsk. The SSF concerned with equatorial plasma bubble is only observed at low latitude station Hainan and the branch SF is only observed at high latitude stations Yakutsk and Zhigansk. For most cases start time of SF is later if the station latitude is lower. This implies that plasma instability caused ionospheric irregularity is propagation from high latitude to low latitude ionosphere.; The ionospheric spread-F has many significant effects on radio waves that propagation through the Earth's atmosphere, such as refraction, reflection, absorption, time delay, phase change, amplitude change, Doppler shifts, and so on.
