Regularities of warming observed in Siberia Regularities of warming observed in Siberia Analysis of unterannual changes of temperature regime Leading role of atmospheric circulation is characteristic for warming in Siberia in 20 th century (mostly due to winter months of recent decades) From correlation analysis of wavelet spectra the climatic phenomenon has been revealed in the middle of 20 th century, namely, high correlation between T and NAO index periodicities with the scale of 30-50 years Periodicity scale, years Analysis of phase shifts for T and NAO index wavelet spectra revealed delay of up to 7 years between the above periodicities . This fact is associated with inertial mechanisms of heat transfer by oceanic fluxes Wavelet location, years
