英文摘要In this paper, the CESE-HLL three-dimensional magnetohydrodynamic solar wind model is first modified to be able to work in a corona-heliosphere integrated approach and then used to simulate the evolution of solar wind from the solar surface to the Earth's orbit during year 2008. Here high-cadence photospheric magnetic field data are used to drive the model at the solar surface via the projected normal characteristic boundary equations. The simulated results are analyzed and quantitatively evaluated by comparing the simulated results with solar and interplanetary observations. The analyses demonstrate that our model reproduces the main pattern and the evolutionary feature of large-scale coronal structures. The simulated results show that the height of the pseudostreamer X point is positively correlated with the distance of the coronal holes connected by the pseudostreamer. During year 2008, the helmet streamer belt is found to have a net southward displacement from the equator while the pseudostreamer belts are biased to the Northern Hemisphere. Both helmet streamer belt and pseudostreamer belts exhibit a general trend of becoming more concentrated along the equator throughout 2008. The evaluation of the simulated results at the L1 point shows that the general structures can be generated by the model, and that speed is the best among the solar wind parameters reproduced. However, the temperature of the fast solar wind and the magnitude of the interplanetary magnetic field are underestimated. The success rate of prediction and arrival time error are also calculated for magnetic field polarity reversals and stream interaction regions.
