| 摘 要： | 对江南北部地区梅雨期降水和海温的SVD分析结果表明，与江南北部地区梅雨期降水异常相关的海温分布型是西正东负型，关键区恰好处于相关最显著的部位。前一年10—12月为海温的关键影响时段，且与梅雨期降水有很好的正相关关系。在该海温异常型的影响之下，江南北部地区次年梅雨期降水异常表现为同位相变化特征，而长江以南的下游地区为受其影响最显著的区域。 |

| Abstract: | SVD analysis of the relationship between northern Jiangnan Meiyu season precipitation anomalies and sea surface temperature anomalies(SSTA) shows that correlated SSTA distribution displays a pattern of west-positive-east-negative.The key region is just located in the most significant correlation area.The time period of the significant SSTA impact is from October to December in the previous year,i.e.the SSTA in the period is closely positively correlated with the Meiyu precipitation in northern Jiangnan.Under the influence of the SSTA pattern,the precipitation anomalies in the following Meiyu period in northern Jiangnan would exhibit a in-phase feature,and the most remarkable correlation region is the south part of the lower reach of the Changjiang River. |
