These regions located at the two ends of the PDO-related summer rainfall dipole. The warm phases of the PDO coincide with anomalous dry periods in both North and South China, and wet periods in the middle and lower Yangtze River Valley. The opposite moisture regimes exist in cool phases. This pattern is a result of changes in the strength of the summer monsoon and the position of the subtropical high altered by the PDO. During warm phases, the summer monsoon is weak, and the strong subtropical high is located far to the south and west. Therefore, the summer rainfall in eastern China can provide useful information about the PDO. #------------------- # Publication # Authors: Shen, C., W.-C. Wang, W. Gong, and Z.

Here we used a data set of the drought/flood index (a proxy of summer rainfall) since 1470 AD to reconstruct the annual PDO index. The reconstruction indicates that the PDO is a robust feature of North Pacific climate variability throughout the study period, however, the major modes of oscillation providing the basic PDO regime timescale have not been persistent over the last 530 years. The quasi-centennial (75-115-yr) and pentadecadal (50-70-yr) oscillations dominated the periods before and after 1850, respectively. Our analysis suggest that solar forcing fluctuation on quasi-centennial time scale (Gleissberg cycle) could be the pace-maker of the PDO before 1850,and the PDO behavior after 1850 could be due, in part, to the global warming. #------------------- # Funding_Agency # Funding_Agency_Name: Biological and Environmental Sciences, Office of Sciences, U.
