SYSTEM AND METHOD FOR EVALUATING OF THE PERFORMANCE OF GLOBAL CLIMATE MODELS

摘要

PURPOSE: A system and a method for evaluating the simulation performance of a global climate model are provided to increase the reliability of climate prediction by reducing the climate prediction uncertainty of the East Asia. CONSTITUTION: A method for evaluating the simulation performance of a global climate model includes the following: climate data are detected from global climate simulation data and global observing data(S201); the signal-to-noise ratio, the empirical orthogonal function, the correlation coefficient, the standard deviation of the climate data are calculated(S202); the empirical orthogonal function of the global observing data is calculated(S203); the correlation coefficient of the empirical orthogonal function of the global observing data is calculated; the correlation coefficient and the standard deviation of the global climate simulation data and the global observing data are calculated to verify the climate simulation capability of a global climate model(S204); and the calculated correlation coefficient is compared with a saved boundary value to select a global climate model with superior simulation performance(S205, S206).
