Zusammenfassung |
Using the extension of Monte Carlo Singular System Analysis
(MC SSA), based on evaluating and testing the regularity of the
dynamics of the SSA modes against the colored noise null
hypothesis, we demonstrate detection of oscillatory modes with
period of about 27 months in records of monthly average
near-surface air temperature from several European locations, as
well as in the monthly North Atlantic Oscillation index. According
to their period, the detected modes can be attributed to the
quasi-biennial oscillations (QBO). The QBO modes extracted from
the temperature and from the NAO index underwent synchronization
analysis and their phase synchronization has been confirmed with
high statistical significance. |
