A possible mechanism for the co‐variability of the boreal spring Antarctic Oscillation and the Yangtze River valley summer rainfall

Abstract: A significant correlation between the boreal spring Antarctic Oscillation (AAO) and the Yangtze River valley summer rainfall (YRVSR) has been found in previous studies, although the mechanisms that might lead to such far-reaching teleconnection remain unresolved. In this study, one of possible mechanisms responsible for the co-variability of the boreal spring AAO and the YRVSR is proposed. It follows that the convection activity over the region of the Maritime Continent serves as a bridge linking the boreal sp… Show more

“…SST anomalies associated with summer LLA CEFs emerged to the north and east of Australia in spring (Fig. 5) and then spread northward and intensified in summer, accompanying the seasonal advancement of the intertropical convergence zone (Sun et al, 2009). The spring LLA CEFs and summer rainfall observations show a correlation pattern quite similar to that of summer CEFs and rainfall (with negative values in the region between middle Yellow River and Yangtze River and positive in southern China), though the significant area was much smaller (not shown).…”

“…More recently, the Antarctic Oscillation (AAO) has been found to be related to the climate of the Northern Hemisphere, particularly to the East Asian summer monsoon (Xue et al 2003;Gao et al 2003;Wang and Fan 2005;Sun et al 2009) and to dust event frequency through atmospheric teleconnections (Fan and Wang 2004). These linkages suggest that this remote southern atmospheric oscillation may also significantly a¤ect climate variability in the Northern Hemisphere.…”

“…and East Asian summer rainfall 3.1 Characteristics of convective activity over the WTP Many studies (Nitta 1987;Huang and Sun 1992;Lau et al 2000;Lu 2001;Sun et al 2009) have addressed the effect of the low-level circulation in the tropical western Pacific on the variability of rainfall over the East Asian region. These findings clearly show that the convective activity induced by heating in the WTP is closely related to East Asian summer rainfall.…”
