摘要
简要介绍了小波分析的原理与方法,并根据武汉和上海两个代表性测站523年的旱涝资料,利用小波变换技术对长江中下游地区在不同时间尺度上的旱涝周期进行了比较和诊断。同时,对长江中下游地区未来的旱涝趋势作了初步的分析。结果表明,小波分析在气候预测中具有一定的优越性。
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.
