Other AbstractBased on the 3D global MHD numerical simulation data under extreme solar wind conditions,a dynamic 3D asymmetric magnetopause model under extreme solar wind conditions is developed.This magnetopause model parameters are fitted by the Levenberg-Marquart method and this magnetopause model has the ability to describe the saturation effects of the solar wind dynamic pressure P_d on the flaring of the magnetopause,the saturation effects of the interplanetary magnetic field(IMF) B_z on the subsolar standoff distance,the magnetopause indentation in the cusp region, the magnetopause asymmetry and the movement of magnetopause indentation center.On the basis of this model under extreme solar wind conditions,the subsolar point decreases with increasing P_d and increasing P_d causes the decrease of the magnetopause size but almost keeps the magnetopause shapes self-similar;with increasing southward(IMF) B_z,the subsolar point decreases slightly,the flaring of the magnetopause decreases and magnetopause indentation center moves towards lowlatitude. Through analysis of the solar storm on August 1,2010,it is found that this magnetopause model can describe the global magnetopause location and shape under extreme solar wind conditions.
