摘　　要：The Jovian magnetosphere is modulated by the solar wind and centrifugal force. The configuration of the magnetic field in the previous model of the magnetosphere including the centrifugal force is consistent with the observations at low magnetic latitude （Λ〈50°）, while there is a substantial difference between the results of the model and the observations at high magnetic latitude （Λ≥50°）, especially in the distant magnetotail. Based on the previous model, a new configuration of the Jovian magnetosphere in the night side is suggested by a three-step transformation in this study. The new magnetosphere obtained by the transformation method is flattened in the z-direction and stretched in the x-direction in distant magnetotail, which agree with general knowledge.The Jovian magnetosphere is modulated by the solar wind and centrifugal force.
