| Abstract: | The basic principle and method of wavelet analysis are briefly introduced. Based on 523 years of drought and flood data set in Wuhan and Shanghai, the periods on different time scales of drought and flood along the middle to lower reaches of Yangtze River are compared and diagnosed by using wavelet analysis technique. The future tendency of drought and flood in this area is also analyzed. The results indicate that the wavelet analysis to some extent has advantages on climate prediction. |

| Keywords: | wavelet analysis drought and flood climate prediction |
