Popis:	Conditional nonlinear optimal perturbation has been widely used in predictability and sensitivity studies of nonlinear numerical models. The main solution for CNOP is the adjoint-based method. However, many modern numerical models have no adjoint models which thus lead to a limitation of CNOP applications. To alleviate the limitation, we propose an ensemble projection method based on the orthogonal neighborhood preservation projection. To demonstrate the validity, we apply our method to CNOP of the Zebiak-Cane model and make a comparison with the adjoint-based method. Experimental results show that the proposed method can obtain similar results with the adjoint-based method.
