HAAR WAVELET ANALYSIS OF CLIMATIC TIME SERIES
International Journal of Wavelets, Multiresolution and Information Processing, 2014 In order to extract the intrinsic information of climatic time series from background red noise, in this paper, we will first give an analytic formula on the distribution of Haar wavelet power spectra of red noise in a rigorous statistical framework. After that, by comparing the difference of wavelet power spectra of real climatic time series and red ...
