This paper discusses how to develop adjoint model(ADM) and tangent linear model(TLM) of the parallel model based on shallow water equation.The parallel strategy of TLM is the same as the original parallel model.Parallel strategy of ADM is different.The three adopt uniform domain decomposition in order to improve the parallel efficiency.One domain decomposition is adopted on cluster parallel computer system.The computing cost of TLM is about as double as the original model and ADM's is about 3 times as that.The communication cost of ADM is about as double as the original parallel model.The speed-up of TLM is the best among three models.
