| 摘 要： | 本文利用1954～2005年中国740站逐日降水资料和NCEP/NCAR再分析资料,分析江淮夏季降水季节内振荡(ISO)的年际变化,并讨论了异常年的海气背景特征.诊断分析的结果表明:(1)当江淮夏季降水ISO活跃时,江淮流域、孟加拉湾、南海及其以东海域和日本南部海区上空大气都表现出显著的季节内振荡特征.在江淮夏季降水不...

| Abstract: | Based on the 740 stations' daily rainfall datasets in China from 1954 to 2005 and the NCEP/NCAR reana-lysis data,the interannual variability of the intraseasonal oscillation(ISO) of summer rainfall over the Yangtze-Huaihe River basin was analysed and the associated air-sea features were discussed.The results are as follows:(1) when the ISO of summer rainfall is more active,the 30-60-day oscillation is significant in atmosphere over the Yang-tze-Huaihe River basin,the Bay of Bengal,the South China Sea and th... |
