| 摘 要： | Relationship between the onset date of South China Sea (SCS) summer monsoon and the summer rainfall in Shandong Province was examined by comprehensive analysis to establish a conceptual model of the link. If the summer monsoon occurs earlier, the 500 hPa level would induce the teleconnection of Eurasian pattern in the summer (June-August), which indicates that the western Pacific subtropical high is displaced northward further than usual, the Siberian high is intensified and the Okhotsk low is deepened. Under such circumstance, Shandong, located in the west side of the subtropical high and in front of the mid-Siberia high, would be expected to have a wet summer because it is quite possible for cold and warm air to meet and interact with each other in Shandong. Statistical analysis revealed that the 500 hPa anomalies over Korea and Japan were sensitive to the SCS monsoon onset date and very important to precipitation in Shandong, and that the convective activities over the deep water basin in the SCS in 24-26 pentads significantly influenced the position of the ridge line of the western Pacific subtropical high. These findings yielded better understanding of the causative mechanisms involved in the precipitation generation, so that the knowledge gained can possibly be applied for long-lead forecast.

| Abstract: | Relationship between the onset data of South China Sea (SCS) summer monsoon and the summer rainfall in Shandong Province was
examined by comprehensive analysis to establish a conceptual model of the link. If the summer monsoon occurs earlier, the
500 hPa level would induce the teleconnection of Eurasian pattern in the summer (June–August), which indicates that the western
Pacific subtropical high is displaced northward further than usual, the Siberian high is intensified and the Okhotsk low is
deepened. Under such circumstance, Shandong, Iocated in the west side of the subtropical high and in front of the mid-Siberia
high, would be expected to have a wet summer because it is quite possible for cold and warm air to meet and interact with
each other in Shandong. Statistical analysis revealed that the 500 hPa anomalies over Korea and Japan were sensitive to the
SCS monsoon onset date and very important to precipitation in Shandong, and that the convective activities over the deep water
basin in the SCS in 24–26 pentads significantly influenced the position of the ridge line of the western Pacific subtropical
high. These findings yielded better understanding of the causative mechanisms involved in the precipitation generation, so
that the knowledge gained can possibly be applied for long-lead forecast.
