| 中文摘要 | In this paper, a preliminary study of the global corona for Carrington rotation (CR) 2055 is carried out by the 3D Solar-Interplanetary (SIP) adaptive mesh refinement (AMR) space-time conservation element and solution element (CESE) MHD model (SIP-AMR-CESE MHD model) (Feng et al. 2011a), which is driven by the daily-updated magnetic field synoptic data. To incorporate the observations into the model, the lower boundary conditions are specified according to the flux evolution of the observed magnetic field and the normal projected characteristic method. The simulated results are compared with solar observations and in-situ solar wind measurements, which are mapped from both Ulysses and other near-Earth spacecraft to the computation domain. Comparisons show that the MHD results have good overall agreement with coronal and interplanetary structures, including the size and distribution of coronal holes and the transition of the solar wind speeds and magnetic field polarities. The MHD results are also compared with the Potential Field Source Surface (PFSS) and Wang-Sheeley-Arge (WSA) methods. |
