Abstract

An extended data set of magnetopause crossings observed at geosynchronous orbit was collected for nine major magnetic storms that occurred from 2000 to 2005. The new set of geosynchronous magnetopause crossings (GMCs) was used for comparative analysis of several magnetopause models during severe, strong, and extremely strong magnetic storms. The analysis allowed verification of specific effects such as saturation of an influence of interplanetary magnetic field Bz and dawn-dusk asymmetry. It was shown that the effects of saturation and duskward magnetopause skewing were important on the main phase of magnetic storms. Among the models considered, the most accurate prediction of GMCs was found for three models: Kuznetsov and Suvorova (1998a), Lin et al. (2010), and Dmitriev et al. (2011). The model by Lin et al. (2010) demonstrated the best capability of GMC prediction in a wide range of geomagnetic disturbances from severe to extremely strong magnetic storms.
