A GLOBAL MODEL OF MAGNETIC RECONNECTION AT MAGNETOPAUSE FOR NORTHWARD IMF

摘要: 在对背阳面磁层顶区局域磁场重联模拟的基础上提出了一个行星际磁场北向时磁层顶磁场重联的全球模式。行星际磁场北向时碰层顶磁场重联导致近地尾瓣的能量被输送到远磁尾,太阳风能量不在磁尾储存,向阳面磁层顶变厚,磁层受到一系列扰动。Abstract: A 2D compressible model is used to simulate the local magnetic reconnection at the nightside magnetopause for northward IMF. Based on the simulation result, a globe magnetic reconnection model for northward IMF is proposed. As results of magnetic reconnection at magnetopause for northward IMF, the magnetic energy in tail lobe is transported to far magnetotail, dayside magnetopause become thicker, and the magnetosphere is disturbed.
