  • Using 86 CME-interplanetary shock events, the correlation between the peak values of (a) the solar wind parameters (Bz, Ey, Pdyn) and the geomagnetic indices (SYM-H, ASY-H, Kp), (b) the coupling functions (Borovsky, Akasofu, Newell) and the geomagnetic indices, (c) the solar wind parameters/coupling functions/geomagnetic indices and the ionospheric parameter (Δf0F2min), are investigated. The statistical results show that in group (a), Bz min and SYM-Hmin have the best correlation, that in group (b), the best correlation is between the peak values of Akasofu function (Amin) and SYM-Hmin, and that in group (c), the best correlation is between Kpmax and Δf0F2min. Based on the statistical results, a method for predicting f0F2 of a single station is attempted to be set up. The input is modified Bz min and the outputs are SYM-Hmin and Δf0F2min. Then 25 CME-IPS events that caused geomagnetic storms in 1998 and 2009 are used to check the prediction method. The results show that our method can be used to predict SYM-Hmin and Δf0F2min.
