Abstract: The variation of temperature and precipitation in the Yellow River Basin was analyzed based on meteorological data at 54 metrological stations during 1961-2010. The results showed that the annual precipitation increased in upper and decreased in middle of the Yellow River Basin. The precipitation increased in upper in spring, decreased in midlist in autumn, and increased during whole winter, especially from January to March, and December. Temperature increased, but maximum and minimum temperature changed non symmetrically. Annual maximum, mean and minimum temperature increased with an amplitude peak in winter in whole basin, which increased obviously in summer and autumn.The increase rate of monthly mean temperature was highest, followed by monthly minimum temperature. It tended to warming wetting during winter in whole basin and same in upper during spring, warming drying in autumn in middle stream.
