摘　　要：考虑到当前暖区降水和锋面降水的时空分布特征模型由于指标选取不当,导致特征分析结果与真实时空走向相差较大的问题,构建新型暖区降水和锋面降水的时空分布特征分析模型。使用经验正交函数对真实降水数据进行处理,得到模型所需的数据基础。提取时空分布特征分析模型参数,获取时空分布特征分析参考条件。将相关数据导入相关计算软件中,构建降水时空分布特征分析模型。构建实验分析环节,对此模型的使用效果加以分析。实验结果表明,此模型的所得时空分布特征与真实降水走向一致,由此可知此模型的使用效果优于当前模型。The results and trends predictions of the current spatio-temporal distribution characteristics model for warm areas are inaccurate due to the improper selection of indicators.A new spatio-temporal distribution characteristics analysis model is constructed.The empirical orthogonal function is used to process the real precipitation data and obtain the data base required by the model.The parameters of spatio-temporal distribution analysis model were extracted and the reference conditions of spatio-temporal distribution analysis were obtained.The relevant data were imported into the relevant computing software to build the analysis model of the spatial and temporal distribution characteristics of precipitation.The experimental analysis link was constructed to analyze the application effect of the model.The experimental results show that the spatial and temporal distribution characteristics of the model are consistent with the real precipitation trend,which indicates that the application effect of the model is better than the current model.
