“…The average amount of precipitation and its dependence on the different QBO phases were studied in Eastern, Western and Central Europe (Brazdil, Zolotokrylin 1995). In most of Europe, statistically significant results were obtained in May, September and October, but these results differ pretty much from the results of this paper.…”

“…The statistically significant precipitation differences between the easterly and westerly QBO phases were established for May and September (90 % validity) and November (95 %). These results are the opposite of the results obtained for Central Europe and British Isles and coincide with the results obtained for the territory of Belarus in 1953-1972 (Brazdil, Zolotokrylin 1995).…”

“…A contrary situation occurs in the eastern part of the Ukraine and in the adjacent part of Russia where a strong signal yet of different character was observed in May: greater amounts of precipitation and their lower changeability were recorded during the westerly phase. The difference can be accounted for by diverse circulation patterns during the different QBO phases (Brazdil, Zolotokrylin 1995). The results obtained by measurements of maximal temperatures, NAO index and QBO in the North Atlantic using different statistical methods provide basis for assumption that these oscillations are interrelated what is proved by the high correlation coefficient.…”

The quasi-biennial oscillation (further -QBO) is a quasi-periodic oscillation of the equatorial zonal wind between easterlies and westerlies in the tropical stratosphere with a mean period of 26 to 29 months. Together with other circulation mechanisms, the QBO comprises a global climate system which affects the climate indices of different regions of the globe including Lithuania. The authors of the present paper chose to address the issue of the anomalies of precipitation in Lithuania. The research encompasses the time frame from 1953 to 2009: relationship between the periods without precipitation for 10 and more days, monthly precipitation sum and different phases of QBO. The highest statistically significant precipitation deviations according the QBO phase at the 30 hPa level were established to be in May, September and November. The anomalies of precipitation were found to be predetermined by the atmospheric circulation patterns.

“…So far, oscillatory terms in the precipitation field at the 2-3-year periodicity band have been detected across Mediterranean and Europe by many researchers (e.g., Maheras et al 1992;Brázdil and Zolotokrylin 1995;Rodo et al 1997;Corte-Real et al 1998;Karagiannidis et al 2008). Furthermore, significant 2.2-2.3-year oscillatory terms have been also detected in various North Atlantic Oscillation indices (e.g., Rogers 1984;Schneider and Schonwiese 1989;Hurrell and van Loon 1997;Cook et al 1998;Qian et al 2000), as well as in the Southern Oscillation Index (e.g., Allen and Smith 1996;Ghil et al 2002).…”

The present study examines the variability of the precipitation regime across the Ionian Islands complex, Greece (Central Mediterranean), for a period spanning more than one century. Significant negative long-term linear trends in the annual precipitation totals are observed, more pronounced in the southern parts of the studied area, while a climatic discontinuity possibly occurred during the 1970s, manifested first in the southern Ionian. Statistically significant nonlinear trends and subdecadal intermittent oscillations were detected using Monte Carlo singular spectral analysis. The correlation of the winter precipitation variability at Ionian complex with the North Atlantic Oscillation anomalies was also investigated and extended in the frequency domain. Finally, future projections were performed using an ensemble of Regional Climatic Models. Model simulations suggested a decrease of the order of ∼20% or more in the mean annual precipitation of the area by the end of the century.

“…These imply that atmospheric oscillations might influence precipitation across the whole Tibetan Plateau. In fact, although the Quasi-Biennial Oscillation, the Southern Oscillation, and the North Atlantic Oscillation are regional phenomena, they affect global climate (including temperature and precipitation) by modulating atmospheric circulation (Lau and Sheu, 1988;Yulaeva and Wallace, 1994;Brá zdil and Zolotokrylin, 1995;Hurrell, 1995;Baldwin et al, 2001).…”
