| 摘 要： | This paper presents a composite interaction formula based on the discrete-interaction operator of wave-wave nonlinear interaction for deriving its adjoint source function in the wave assimilation model.Assimilation experiments were performed using the significant wave heights observed by the TOPES/POSEIDON satellite,and the gradinet distribution in the physical space was also analyzed preliminarily.

| Abstract: | This paper presents a composite interaction formula based on the discrete-interaction operator of wave-wave nonlinear interaction for deriving its adjoint source function in the wave assimilation model. Assimilation experiments were performed using the significant wave heights observed by the TOPES/POSEIDON satellite, and the gradient distribution in the physical space was also analyzed preliminarily. |
