摘　　要：该文利用Ｔ６３Ｌ１６和日本数值预报产品，采用相关分析方法提取典型因子场，再由典型因子场选点求取平均场及极值场，用逐步回归法制作黄河三角洲地区汛期降水预报。The data of T63L16 and NWP of Japan are used to select the canonical factor fields.Based on the correlations analysis,the average and maximum fields are then made by the use of the canonical factor fields.The regression analysis is used to forecast precipitation during flood season in the Yellow River delta.Results show that the regression equations have value in the operational forecast.
