In this study, we analyzed the characteristics of summer rainfall over South Korea during recent five(2009-2013) years using observation data. There was a significant contrast in interannual variability between July and August rainfall since 1998. Large increase of rainfall in July (2009 and 2011) and August (2010 and 2012) were found to be consistent over all 60 stations in South Korea. Enhanced precipitation over western tropical Paciÿc and anticyclonic anomaly to the east of Korean peninsula were the common features when there was rainfall increase both in July and August. Intraseasonal summer rainfall over South Korea evolves in time lag with intraseasonal Indian and Western North Pacific monsoon indices. The meridional tripole structure of intraseasonal convection from the Western North Pacific to East Asia and the baroclinic structure of intraseasonal circulation anomalies centered over Korean peninsula provided a favorable condition for the extreme rainfall(90 percentile) events to occur.
