子午面磁层顶位形结构的MHD模拟研究
An MHD Simulation Study on the Location and Shape of Magnetopause in Meridian Plane
摘要
Abstract
Based on the Solar wind-Magnetosphere-Ionosphere coupling global MHD simulation, the position and shape of the noon midnight meridian plane magnetopause under several solar wind dynamic pressure and interplanetary magnetic field (IMF) conditions are studied. The simulation results show that,in the noon midnight meridian,plane magnetopause shape has a concave structure. And at certain Dp,when southern IMF Bx(Bx<0) increases,the subsolar position (ro) of the magnetopause decreases and when northward (Br>0) increases, the subsolar position r0 keeps gradually increasing. Significant decreasing of r0 appears with the increase of Dp. For all cases studied,the flare angle (z0/x0) of the magnetopause increases when (Bx<0) increases. These simulation results are consistent with the empirical results based on satellite data in high-latitude empirical model (BOO) and (Schield) model. That is to say,MHD simulation is an effective tool to study the magnetopause shape. It is an effective way,based on the configuration of physical theory on magnetopause numerical simulation data,to solve the problem that relates to the obtaining of transversing data in high latitudes being limited.关键词
