Prediction of Summer Temperature with SVD in Northeast China

Base on the summer temperature from 80 observational stations of Northeast China and North Pacific sea surface temperature(SST) data from 1961 to 2002, the relationship between the SST of the preceding winter and the summer temperature in Northeast China is studied with the Singular Value Decomposition(SVD). The results show that the SST in preceding winter has a very close relationship with the summer temperature in Northeast China. The prediction method based on the SVD is developed. The predict-examination in the last years shows that the method has the ability of prediction and steady character.
