Multiple time scales analysis of precipitation in Hotan, China

The wavelet transform and detrended fluctuation analysis (DFA) were introduced briefly. Then DFA and discrete wavelet were used to analyze the fluctuation characteristics of precipitation in Hotan from 1954 to 2003. It was shown by analysis with the methods of de-trend fluctuation and wavelet transform that the precipitation in Hotan will decreased in near future for several years, and will last 21 months at least.
