Based on the stream discharge data (1961-2001) of the Manas river in Xinjiang province and the temperature and precipitation data of nine meteorological stations in northern Xinjiang, the characteristics and laws of stream discharge, temperature, and precipitation were analyzed, which were also been made correlation analysis with North Atlantic Oscillation Index. The study shows that in winter the NAO index has positive relationships with stream discharge, while in summer the relationships are negative, and the NAO index has significant relationships with temperatures and precipitations both in winter and summer. Moreover using cross wavelet analysis, the authors found the closest oscillation periods of the relationships between the NAO index and the stream discharge of the Manas river in winter and in summer, also the characteristics of which in different timescale were analyzed.
