A simple statistical test is proposed for matching the peaks occurring in two spectra, and an application to rainfall data is described. By comparing the spectra of related variables, small peaks in the rainfall spectra are shown lo contain information. However regularities in the occurrence of minima and maxima in climatological spectra can be explained by non‐linearities in the noise portion of the input data.
