The relationship between soil moisture and precipitation has became a research focus,because soil moisture has the “memory”.Using the data of soil moisture from CPC (Climate Prediction Center) and the SVD (Singular Value Decomposition) method,the influence of soil moisture on summer precipitation in Tibetan Plateau (TP) in spring was discussed.The results showed that the cumulative covariance percentages of the first two modes reached 59.15%,and the time correlation coefficients of the two field expansion sequences were 0.78,reflecting the main characteristics of the two field relations.The soil moisture field shows the consistency of the north and south phases;however,the consistency of the precipitation field was weak.The first mode indicated that when the soil moisture in the northern part of the TP in spring was higher than that of other areas,the precipitation in the northern and southeastern part of the TP in summer was lower than that of other areas.The second mode indicated that when the soil moisture was higher than that of other areas in most areas of the TP in spring,the precipitation in the northern and central parts of the plateau was higher than that of other areas in summer,and the precipitation in the southern part was low.The 500 hPa circulation and precipitable water field match well.When the soil moisture was relatively high in spring,negative anomalies were controlled in the northern part of the TP,and the corresponding high-level precipitation was relatively large.The configuration was conducive to more precipitation in the southwest of the TP.
