A Prediction Method for△f0F2min of a Single Station From Interplanetary Parameters Based on Statistical Study
摘要
Abstract
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（△f0F2min）, 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 （pmax and △f0F2min）. Based on the statistical results,a method for predicting f0F2 of a single station is attempted to be set up.The input is modified B_（z min） and the outputs are SYM-Hmin and △f0F2min.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 △f0F2min关键词
