The summer rain patterns in China were further divided into eight types on the basis of the three patterns divided by Liao Quansun et al. The situations of blocking high and subtropical high were combined together with the summer rain of China. Correspondingly, the circulation of 500 hPa was also divided into eight patterns. The correlation coefficients of the January circulation of forecast year with these eight patterns were calculated. The maximum correlation would be selected to be the forecast of that year. In this way, the precipitation predictions of years 2007 and 2008 were successful.
