摘要
本文对北太平洋海温与鲁西南夏季降水关系进行相关分析建立１２个相关场，得出赤道海域、黑潮海域阳北太平洋海域三大主要优势相关区。选出３５个预报因子进行主成份分析，应用前１０个合成主成份变量建立预报方程，收到了较好的预报效果。
Based on correlation analysis of North Pacific SST(Sea Surface Temperature) with SW Shandong summer precipitation,twelve correlation patterns are established,indicating that predominant ocrrelation sea area are cocated in the equatoial rigion,Kuroshio and North Pacific.Principal component analysis is performed among 35 predictors, first ten principal components are used to construct a prognostic epuation.The final results are satisfactory.
