STOCHASTIC VARIABILITY IN THE ATMOSPHERIC ACTIVITY OF JUPITER

The atmospheric activity of Jupiter exhibits quasi-periodic character attributed to the stochastic nature of the involved mechanisms. Period icities between 4-33 years are obtained employing four spectrum analys is methods, (power spectrum employing the Blackman-Tukey window, maxim um entropy, Fourier, autocorrelation), whilst, their significance and their stationarity has been established with the application of genera l statistical tests (Kolmogorov-Smirnov, one sample and two sample tes t, randomness test, chi-square, various orders of autoregressive proce ss, analysis of truncated records).
