Statistical Structure of Air Electric Conductivity in Dusheti
Results of analysis of the statistical structure of mean six month and yearly values of total air electric conductivity (accordingly Ywarm, Ycold and Y) in Dusheti have been considered (in latitude 42.08 degrees, in longitude 44.7 degrees, 900 m altitude a.s.l.). An observation period makes 25 years, from 1966 to 1990.The correlation analysis of the indicated time-series of observations is carried out (coefficient of linear correlation, Kendall and Spearmen rank correlation coefficients, autocorrelation coefficient). It is obtained, that all three indicated time-series are autocorrelate and non accidental. The estimation of confidence interval of mean values of air electric conductivity taking into account and without taking into account the data about the values of autocorrelation coefficient is carried out. The trend + background and random components of time-series of the air electric conductivity are studied. Trend of the mean half year and annual values of air electrical conductivity is negative and satisfactorily approximated by linear equations.
