Regularities of water flow cyclic fluctuations at rivers in Western Siberia

Regularities of mid-annual flow long-term fluctuations at rivers in Western Siberia in the conditions of modern climate change are investigated. By an original technique of processing the coherence coefficients, received in the wavelet-analysis, allocation of areas on character of mid-annual flow recurrence at rivers during 1955-2005 years are spent. Territorial features of change the characteristic periodicity which can influence functioning of natural complexes of Siberia are revealed.
