  3. 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
