A search for extreme points for the correlation coefficients of UOHT and Cl, SA and Cl was made by applying the method of successive phase displacement (from 1 to 29 months onward and backward) o f Cl o f respective planets. Also, the positions of the closest and, as a rule, local extreme points allowed to detect phase displacements of some processes in respect to other ones and to estimate correlations (direct or inverse). Furthermore, the dynamics of changes in the correlation coefficients was used to separate a general rhythm (periods between local maximum points o f r, in months) for each pair of processes. On manifestation ofperiodical disturbances o f interplanetary medium influctuations o funtil oxidation half-time Fig. 1. Components of UOHT Sb S7 (curves 2-8) resulted from adaptive filtration of the primary range of monthly average values (1). As there is a frequency pulsation in the curves Sb ..., S7, manifesting themselves as wave trains with the maximum amplitude in the center of each train (Pic.l), we added the values of their periods (underlined) to Table 1.

The periods of rhythmic processes of circa 40 months (with Cl of Mrc-Jup) and circa 22 months (with Cl of mar-Npt) are in agreement with the results of spectral analysis. The period of 42.67 months was detected in the
