摘要：

Maximum entropy spectral analysis for the estimation of power spectra is used to study monthly and annual spectra of air temperature and precipitation at 63 weather stations in Duero Hydrographic Basin. Annual data are first submitted to the maximum entropy method (MEM) and the resulting power found are analysed. These spectra were then stratified according to the spectral peaks and on this basis several climatic regions were defined for the Duero Basin. The MEM spectral estimates of monthly values clearly show the annual and semi-annual cycle.
