| Abstract: | Temporal variability of the relationship between the phases of quasi-decadal oscillations (QDOs) of total ozone (TO), measured
at the Arosa station, and the Ri international sunspot number have been analyzed for the period of 1932–2009. Before the 1970s, the maximum phase of ozone
QDOs lagged behind solar activity variations by about 2.5–2.8 years and later outstripped by about 1.5 years. We assumed that
the TO QDOs in midlatitudes of the Northern Hemisphere were close to being in resonance with solar activity oscillations in
the period from the mid-1960s to the mid-1970s and assessed the characteristic delay period of TO QDOs. The global distribution
of phases and amplitudes of TO QDOs have been studied for the period from 1979 to 2008 based on satellite data. The maximum
phase of TO QDOs first onsets in northern middle and high latitudes and coincides with the end of the growth phase of the
11-year solar cycle. In the tropics, the maximum oscillation phase lags behind by 0.5–1 year. The maximum phase lag near 40–50°
S is about two years. The latitudinal variations of the phase of TO QDOs have been approximated. |
