Abstract

This work investigates the relationship between the seasonal streamflows and the dominant modes of climate variability. For this work, monthly and seasonal data from 33 hydrometeric stations located in the NORTHWEST OF IRAN were used during the period of 1971-2009. CONTINUOUS WAVELET TRANSFORM was implemented on the mean seasonal streamflows for all sites. CROSS-WAVELET analysis was also applied to the seasonal streamflows and three selected teleconnection indices [North Atlantic Oscillation (NAO), Pacific-North America (PNA) and Southern Oscillation Index (SOI)]. The wavelet cross-spectra of all seasons revealed strong climate-streamflow covariance within (2–6)-years time interval just after 1991. CORRELATION ANALYSIS within (2-6)-years time interval between the seasonal streamflow and the selected teleconnection indices showed the largest positive correlations with the NAO, for spring and winter seasons after the change point (1991). In contrast, PNA and SOI showed statistically significant correlations for all seasons before 1991. The CROSS-WAVELET spectra and the CORRELATION ANALYSIS within (2–6)-years interval also confirmed the occurrence of a change point around 1991 in seasonal streamflows.
