中文摘要: 应用东北区91个测站1955～2000年夏季(6～8月)逐日降水资料和相应的NCEP/NCAR逐日水汽输送资料,分析了该区夏季降水的区域特征,并进一步研究其多雨年的水汽异常输送特征。结果表明,东北地区的夏季降水异常具有明显的区域性,可分为6个独立的区域。对各区域多雨年和降水正常年的水汽异常输送进行对比分析,发现各区域多雨年的水汽异常输送路径和关键区均存在明显的不同。

Abstract:Based on daily summer rainfall data 1955—2000 at 91 stations in Northeast China and corresponding NCEP/NCAR water-vapor transportations, the regional characteristic of summer rainfall in Northeast China is analyzed, and further research of the features of abnormal water-vapor transportation of the flood years is carried out. The results show that the summer rainfall anomaly of Northeast China has obvious regional characters, there are six independent areas there. The study of the differences of water-vapor transportation between the flood years and the normal years indicates that the paths and key regions of the anomaly water-vapor transportation of one area are different completely to the other's.
