Some statistically significant periodicities in the 2-6 years band, which are assumed to be associated with the El Nino occurrences, were found in the regional modular series of both parameters in Turkey.eninfo:eu-repo/semantics/openAccessEl Ninospectral analysisprecipitationstreamflowTurkeyArticle138719725N/AWOS:000224087300005Q4
