Time series of 16, 20 or 24 years of temperature data from 18 Italian stations were analyzed on a statistical base. The results of classical statistical analysis of climate data were compared with corresponding results of Fourier analysis. It was found that time series of temperature can be described by two components: a mean represented by a maximum of 19 Fourier complex coefficients, the stochastic component. A method is described to obtain a typical annual type function, a monthly mean day and other typical time functions, by means of coefficients of the Fourier Transforms.

Abstract
Time series of 16, 20 or 24 years of temperature data from 18 Italian stations were analyzed on a statistical base. The results of classical statistical analysis of climate data were compared with corresponding results of Fourier analysis. It was found that time series of temperature can be described by two components: a mean represented by a maximum of 19 Fourier complex coefficients, the stochastic component. A method is described to obtain a typical annual type function, a monthly mean day and other typical time functions, by means of coefficients of the Fourier Transforms.File in questo prodotto:
