Upon using an artificial neural network ( ann ) a new short-term climate forecast model with the monthly mean rainfall in june in the north of guangxi as predictand is established making empirical orthogonal functions ( eof ) to the 36 predictors ( 15 ssa predictors, 21 500hpa height predictors ) with over 0.05 significant correlation level of previous 500hpa height and sea surface temperature ( sst ) field, and selecting the high relative principal components, at the same time, a new approach of constructing ann learning matrix is developed . predictive capability between the new model ( principal components ann model ) and linear regression model for the same predictors is discussed based on the independent samples and historical samples 本文通过对广西北部6月平均降水量(预报量)同北半球月平均500hpa高度场和北太平洋月平均海温场进行相关普查,选取了前期36个同预报量相关显著水平达到0.05以上的预报因子(15个海温场预报因子,21个高度场预报因子),并运用自然正交函数展开方法对这36个前期预报因子展开,取其中同预报量相关程度高的主成分,结合人工神经网络技术,提出了一种新的构造人工神经网络学习矩阵的方法,建立了一种新的短期气候预测模型。
