摘要
PURPOSE: An ensemble climate predicting method using empirical singular vector is provided to linearlize an atmosphere-ocean model by singular-vector-decomposing empirical function to obtain the singular vector and using the singular vector as initial ensemble perturbation. CONSTITUTION: Empirical function is generated based on past climate data. The empirical function is singular-vector-decomposed to obtain empirical singular vector. The empirical singular vector is used as initial ensemble perturbation. The empirical function is obtained based on general formula 1 and general formula 2. In the chemical formulas, the X and the Xn are initial condition state vector of a dynamic climate model. Y and Y(n+) are the predicated value state vector of the dynamic climate model. The is predication progress time. The L is empirical function. The is error from linear supposition.
