Predictions of the snow water equivalent (SWE) over Siberia in spring (March-April-May) and its relationship with the accompanied summer (June-July-August) precipitation over China are investigated using the reforecast (1983–2010) from the National Centers for Environmental Prediction (NCEP) Climate Forecast System version 2 (CFSv2). The CFSv2 for one month lead (LM0) well predicts the leading pattern of Eurasian SWE in spring, characterized by homogeneous variations over most of Eurasia centered in Siberia. Overall, the CFSv2 for LM0 exhibits a reasonable level of prediction skill for variations of Siberian spring SWE, but the initial SWE in the CFSv2 shows a dominant effect on the re-forecasted Siberian SWE climatology. Using the initial condition in April, the CFSv2 can predict the SWE over the Siberia in May and the corresponding summer rainfall pattern over China. Positive SWE in May in the CFSv2 is associated with negative summer rainfall anomalies in South and North China and part of Northeast China, and with positive anomalies between the Yangtze River and the Huaihe River and over Inner Mongolia and parts of the north of the Tibetan Plateau and southeastern Tibetan Plateau. The result is consistent with observed features.
