Connection of Compound Extremes of Air Temperature and Precipitation with Atmospheric Circulation Patterns in Eastern Europe

Recent studies show an increase in the frequency of compound extremes air temperature and precipitation many parts world, especially under dry hot conditions. Compound have a significant impact on all spheres human activity, such as health, agriculture, energy. Features atmospheric circulation are closely related to occurrence anomalies precipitation. The article analyzes relationship modes with that had greatest Atlantic–European region over territory Eastern Europe past 60 years extreme Combinations humidity conditions (indices)—cold-dry (CD), cold-wet (CW), warm-dry (WD) warm-wet (WW)—were used extremes. Indices were calculated according E-OBS reanalysis data. Estimates between two time series carried out using standard correlation composite analyses, well cross wavelet analysis. Phase relationships intervals for different climatic indices different. period most fluctuations was from 4 12 observed during 1970–2000. coherent WD WW North Atlantic oscillation (NAO) index occurred rather phase, those CD Arctic (AO) antiphase, Scandinavia pattern (SCAND) antiphase.
