太阳风参数组合的计算

太阳风参数组合的计算 COMPUTATION OF THE SOLAR WIND PARAMETERS 王敬芳 Wang Jingfang first-author 地磁指数与太阳风参数组合的关系近年来已有广泛的统计研究。为了弄清与地磁指数相关的太阳风参数组合与太阳耀斑扰动的关系,本文采用2维3分量磁流体动力学（MHD）模型跟踪了耀斑扰动在黄道面内传播的情况,并在地球轨道的不同位置算得了有关太阳风参数组合随时间变化的关系。初步结果表明,这种计算将有助于说明太阳扰动对地磁活动的不同影响。 There have recently becn a number of statistic studies for the geomagnetic index relative to solar wind parameters. In this paper, a numerical study has been made for the solar wind parameters which correlate with geomagnetic index by using 2-dimentional 3-Component magnetohydrodynamical model to understand the correlation between flares and the solar wind parameters. The Computational results show that this kind of numerical studies is useful to illustrate the different effects of solar disturbances on geomagnetic activity. 磁流体力学 计算机模拟 太阳风 地磁指数 Magnetohydrodynamics Computer simulation Solar wind Geomagnetic index 1987-02-01 2021-04-01 2
