A 1750-year variation is confidently identified in all of the three series. The found phase shifts between the oscillations of this period in the three regions are related to a wave drifting from the east to the west at a rate of v ϕ ≈ +0.2° /yr. The correlation between the time series weakens as the characteristic time of the processes decreases. The character of the remaining oscillations in the wavelet spectra is discussed
