Evidence of structured Brownian dynamics from temperature time series analysis
Servizio Meteorologico dell' Aeronautica, 2ºCMR-Aeroporto "De Bernadi", Via de Pratica di Mare, I-00040 Pratica di Mare (Roma), Italy
Abstract. An analysis of time series of monthly mean temperatures ranging from 1895 to 1989 is performed through application of Singular Spectrum Analysis (SSA) to data of several places in the USA. A common dynamics in the reconstructed spaces is obtained, with the evidence of a non-trivial and structured coupling of two Brownian motions, resembling the so-called Lévy flights. The idea that these two correlated functions are related to the zonal and eddy components of the atmospheric motions is suggested.
