英文摘要: In this paper, decadal variability of the Pacific-South America (PSA) mode is examined from year 1871 to 2008 based on the newly developed ocean and atmosphere reanalysis products. The PSA mode, mirroring the Pacific-North America mode in the Northern Hemisphere, emerges as the second EOF mode of 500 mb geopotential height anomalies. The mode displays substantial interannual-decadal variability with distinct timescales between 3–8 and 10–18 years, respectively. The decadal variability of the PSA mode is found to be associated with the coupled ocean–atmosphere interaction over the subtropical South and tropical Pacific. The subduction of the subtropical temperature anomalies in the South Pacific in conjunction with the tropical–subtropical atmospheric teleconnection plays important role in the decadal variability of the PSA mode. © 2015, Springer-Verlag Berlin Heidelberg.
