Abstract

The variable length record method of spectral analysis is considered as a composite of perturbations of a simple harmonic analysis. By smoothing over near neighbours, the composite spectrum can be made to approach the true spectrum. Since the method is computationally expensive, a less costly technique of multiple interpolation is considered and shown to produce equivalent results. This method is suitable for examining the low frequency end of cli ma to logical spectra.

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 to contain information. However regularities in the occurrence of mini
