The aim of the paper is to analyze a possible teleconnection of Quasi-Biennial Oscillation (QBO), South-ern Oscillation (SO), North Atlantic Oscillation (NAO), and Arctic Oscillation (AO) phenomena with long-term streamflow fluctuation of the Bela River (1895–2004) and Cierny Hron River (1931–2004) (central Slovakia). Homogeneity, long-term trends, as well as inter-annual dry and wet cycles were analyzed for the entire 1895–2004 time series of the Bela River and for the 1931–2004 time series of the Cierny Hron River. Inter-annual fluctuation of the wet and dry periods was identified using spectral analysis. The most signifi-cant period is that of 3.6 years. Other significant periods are those of 2.35 years, 13.5 years, and 21 years. Since these periods were found in other rivers of the world, as well as in SO, NAO, and AO phenomena, they can be considered as relating to the general regularity of the Earth.
