摘要

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.
