| 英文摘要 | The observed mars remnant magnetism suggests that there was an active dynamo in the martian core. we use the mosst core dynamics model to simulate the martian historical dynamo, focusing on the variation of the dynamo states with the rayleigh number ra (a non-dimensional parameter describing the buoyancy force in the core). our numerical results show that the mean field length scale does not vary monotonically with the rayleigh number, and the field morphology at the core mantle boundary changes with rayleigh number. in particular, it drifts westward with a speed decreasing with rayleigh number. |
