FEATURES OF THE HEMISPHERIC NEAR-SURFACE TEMPERATURE VARIATION SYNCHRONIZATION IN OBSERVATIONAL AND MODELED DATA TIME SERIES IN TIMESCALES OF DECADES

Features of variations of the hemispheric surface air temperature and sea surface temperature are considered by means of a specially designed technique of the wavelet analysis (Vakulenko et al., 2004; 2016a; 2016b; 2017) as these are represented in time series of instrumental meteorological observations since the end of the 19th century so far. A strong phase synchronization of these variations between hemispheres and between the land and the sea in timescales of one, two, and six-seven decades is found as well as the absence of such synchronization in the intermediate timescales. It allows to think that the power spectrum of the temperature variations does not continuous in the considered range of timescales (from a year to about one century) as it could be expected if the considered variations were chaotic.
