Abstract:

Three dimensional (3D) Magnetohydrodynamics (MHD) ambient solar wind model is a critical tool for solar-terrestrial coupling process research and space weather forecast. Current development trend of such model is the data-driven 3D MHD ambient solar wind modelling, which uses continuously time-varying solar observations as input, and is able to generate 3D distribution of the ambient solar parameters and its time-dependent evolution. In this paper, the space weather effects of the ambient solar wind and the functions and ingredients of the 3D MHD ambient solar wind model are summarized. The research progress of the data-driven 3D MHD ambient solar wind model in recent years is reviewed. Discussion is made on further development of the data-driven model.

Key words: Magnetohydrodynamics, Solar wind, Numerical Simulation, Data-driven
