Abstract：As solar storms are sweeping the Earth， adverse changes occur in geospace environment. Interplanetary space， as a linking medium of fully understanding space weather process in the Sun-Earth system， is the unique channel for solar storms to propagate from the Sun to Earth. How human can mitigate and avoid destructive damages caused by solar storms becomes an important frontier issue that we must face in the high-tech times. It is of both scientific significance to understand the dynamic process during solar storms propagation in interplanetary space and realistic value to conduct physics-based numerical researches on the three-dimensional process of solar storms in interplanetary space with the aid of powerful computing capacity to predict the arrival times， intensities， and probable geoeffectiveness of solar storms at the Earth. So far， numerical studies based on magnetohydrodynamics （MHD） have gone through the transition from the initial qualitative principle researches to systematic quantitative studies on concrete events and numerical predictions. The main physics-based three-dimensional numerical coronal and interplanetary models include Block Adaptive Tree Solar-wind Roe-type Upwind Scheme （ BATS-R-US）model in Space Weather Modeling Frame （SWMF） developed by the Center for Space Environment Modeling （CSEM）， the coronal and heliospheric （CORHEL） model by the Center for Integrated Space Weather Modeling （CISM） and Solar InterPlanetary-Conservative Element Solution Element （SIP-CESE） model by the solar interplanetary geomagnetic （SIGMA） group of State Key Laboratory of Space Weather， Center for Space Science and Applied Research， Chinese Academy of Sciences. In this paper， we review the main features of the difference schemes in the main three-dimensional numerical physics-based coronal and interplanetary models and their recent research results and outlook the important issues for future research.

Key Words：Interplanetary solar storms； Three-dimensional numerical prediction models； Space weather
