太阳风暴经过地球时,地球空间环境会产生整体剧烈的灾害性变化.行星际空间是太阳风暴吹袭地球空间的必经传输通道,是了解日地系统空间天气整体变化过程的重要纽带.如何减轻或避免太阳风暴所造成的损失是人类高科技时代所面临的重大前沿课题.基于物理的以强大计算能力为基础的太阳风暴日冕行星际过程三维数值研究,不仅具有了解太阳风暴在行星际空间传播的动力学过程的科学意义,还具有预测太阳风暴吹到地球的时间、强度和可能引起的地球空间天气效应方面的现实意义.目前基于MHD方程数值研究行星际太阳风暴的工作已经从初期的定性原理性理论研究过渡到定量的系统性研究具体事件和数值预报试预报阶段.现有基于物理的三维数值预报模型主要有:美国空间环境建模中心(CSEM)开发的空间天气模型架构(SWMF)、美国集成空间天气建模中心(CISM)开发的日冕和日球层模型(CORHEL)和我国空间天气学国家重点实验室SIGMA研究小组开发的太阳行星际守恒元解元(SIP-CESE)三维太阳风模型.本文将概述现有基于物理的主要三维数值预报模型的算法特点及其研究成果,评述行星际太阳风暴的数值模拟研究在今后工作中的努力方向.
As the sun storms pass through the earth, the global space environment will produce an overall and catastrophic catastrophic change.The interplanetary space is an essential transmission channel through which the sun storms hit the earth’s space and is an important link to understand the overall weather and space changes in the space system of Japan and the Earth. Or to avoid the damage caused by the solar storms is a major frontier issue facing the human high-tech era.Research on the three-dimensional numerical study of the interplanetary processes of the solar storm based on the physics based on powerful computational capabilities not only has the understanding of the solar storms in the interplanetary space The scientific significance of the kinetic process and the realistic significance of predicting the time, intensity and potential weather effects caused by the solar storm blowing to the earth.At present, the research on the interplanetary solar storms based on the MHD equation has been carried out from the initial qualitative The theoretical research on the transition from the quantitative to the concrete event and the forecasting stage of the numerical forecasting are as follows: The existing three-dimensional numerical prediction model based on physics mainly includes the Spatial Weather Model Framework (SWMF) developed by the United States Spatial Modeling Center (CSEM) , The United States Integrated Space Weather Modeling Center (CISM) on (CORHEL), and the solar-satellite interplanetary solar-satellite (SIP-CESE) three-dimensional solar wind model developed by the SIGMA research group of the State Key Laboratory of Space Weather of the People’s Republic of China.This article will outline the existing physical- The algorithm features of three-dimensional numerical prediction model and its research achievements are reviewed, and the direction of efforts in numerical simulation of interplanetary solar storms in future work is reviewed.
