Series of rainfall, wind components, sea surface temperature monthly data of the tropical Atlantic Ocean were subjected to cross spectrum and filter analyses. Main interest was directed to teleconnections and phase relationships time lags of the annual cycle and to long-term fluctuations periodicities between one and ten years. The following statistical results are discussed in detail spectra, filtered series e.g. biennial pulse, coherency, and phase differences. The behavior of the biennial cycle and some other results are compared with those of the equatorial Pacific region. Author
