Abstract空间灾害性天气的预报是日地物理学界及高科技领域的热门话题 .未来预测太阳剧烈扰动所造成的行星际风暴到达地球空间的状态势必借助于数值方法 .浅析了空间灾害性扰动事件数值预报存在的问题及未来设想 ,针对这一目的对一维球对称问题提出了处理行星际激波的 6步求解方法 ,指出未来空间灾害性扰动事件预报模式应是一个基于三维的以真实太阳风为背景自洽建立起来的、以太阳等离子体输出及磁场全球结构为初边值、太阳、行星际、地磁因果耦合模式 .
Other AbstractThe prediction of disastrous space weather is a hot topic among solar-terrestrial physics and high technological fields.We propose that the future forecasting of the physical conditions that the violent solar disturbance causes at the earth by propagating in solar wind depends heavily on the numerical method.This paper analyses the existing problems we are facing in the numerical prediction of disastrous disturbance events in solar-terrestrial space,and then gives some suggestions for future study.For such a propose, a six step solution method is developed to deal with one-dimensional synanetric interplanetary shock dynamics. It should be point out that that initialixation of fully self-oonsis-tent 3-D MHD codes considering the solar-interplanetary-geomagnetic coupled relations with initial一boundaryvalues at 1R⊙ of the global output of solar plasma and magnetic field using available solar observations is.essentialrequirerneni in space weather operational codes for forecasting purpose.
