Abstract

Decadal changes in the subseasonal evolution and the phase-locked climatological intraseasonal fluctuation of summertime rainfall over the Korean Peninsula before and after the mid-1990s are investigated. The activity and the migration speed of the monsoon rain band over the East Asian region are altered in the recent decade, resulting in the drier conditions in late spring and the earlier onset of Changma. In early August when a climatological monsoon break was clear in the earlier decade, the precipitation has increased dramatically with a meridional coherency. The response to the enhanced convection over the South China Sea and southeastern China provides a favorable condition for more precipitation in early August through the changes in moisture transport and tropical cyclone passage.
