1. The prediction of disastrous space weather is a hot topi c among solar - terrestrial physics and high technological fields . we propose that the future forecasting of the physical conditions that the violent solar disturb ance causes at the earth by propagating in solar wind depends heavily on the num erical method . this paper analyses the existing problems we are facing in the num erical prediction of disastrous disturbance events in solar - terrestrial space , an d then gives some suggestions for future study . for such a purpose , a six step sol ution method is developed to deal with one - dimensional symmetric interplanetary shock dynamics . it should be point out that that initialization of fully self - con sistent 3 - d mhd codes considering the solar - interplanetary - geomagnetic coupled r elations with initial - boundary values at 1r of the global output of solar pl asma and magnetic field using available solar observations is an essential requi rement in space weather operational codes for forecasting purposes
   空間災(zāi)害性天氣的預(yù)報(bào)是日地物理學(xué)界及高科技領(lǐng)域的熱門話題.未來預(yù)測(cè)太陽劇烈擾動(dòng)所造成的行星際風(fēng)暴到達(dá)地球空間的狀態(tài)勢(shì)必借助于數(shù)值方法.淺析了空間災(zāi)害性擾動(dòng)事件數(shù)值預(yù)報(bào)存在的問題及未來設(shè)想，針對(duì)這一目的對(duì)一維球?qū)ΨQ問題提出了處理行星際激波的6步求解方法，指出未來空間災(zāi)害性擾動(dòng)事件預(yù)報(bào)模式應(yīng)是一個(gè)基于三維的以真實(shí)太陽風(fēng)為背景自洽建立起來的、以太陽等離子體輸出及磁場(chǎng)全球結(jié)構(gòu)為初邊值、太陽、行星際、地磁因果耦合模式
