最优化方法在天气预报中的应用

本文根据最优化方法原理,提出了选择非线性最优预报因子和建立非线性预报方程的办法。试验表明:用此方法选出来的非线性预报因子和建立的方程比线性的好。最后还指出了此方法可推广到预报量离散的情况,建立非线性的判别方程,同时可用于长、中、短期天气预报。

An application of the optimizing method to the weather forecasting

In this paper, a method to select some nonlinear predictors and to build a nonlinear forecasting equation was proposed based on optimization principles. The experiments show both the nonlinear predictors and corresponding equation based on this method are better than those linear equations. Finally, the authors indicate that this method can be extended to building of nonlinear discriminatory equation when predi-ctands are discrete. This method is applicable to various forecastings of long-, medium- and short-ranges.
