| Abstract: | In this paper a new tomography approach, the modal wave-number tomography (MWNT), is proposed for monitoring the cold water mass and a numerical simulation is carried out for the Yellow Sea cold water mass in this paper. A perturbation inversion method is used for inversing the sound speed profile (SSP), with empirical orthonormal functions (EOF) applied to reduce parameter search space. The numerical simulation shows that the modal wave number tomography can be used to invese the average SSP of the cold water mass. Therefore,it shows potential for monitoring ocean internal structure which is range dependent. |
