We simulated the three-dimensional (3D) propagation of a shock wave caused by a coronal mass ejection (CME) on November 13, 2003. The 3D simulations were performed using a high-resolution adaptive mesh refinement (AMR) technique. The AMR technique enabled us to resolve near the sun with (0.06R_◎)^3-sized cells and to resolve the entire shock front with (0.24R_◎)^3-sized cells in an interplanetary simulation within a (500R_◎)^3-sized computational box. The solar wind was measured by an imaginary spacecraft positioned at point L1 in the simulations. A model fitted for solar wind density fluctuations observed by the ACE spacecraft was employed, and models in which some CME parameters were changed were employed for comparison. The relationships between the CME parameters and the solar wind fluctuations were also investigated, and the results were compared with the solar wind data observed at point L1 by the ACE spacecraft.
