|
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...
