Relationships between heavy rainfall over the Korean peninsula and remote tropical cyclones

An investigation has been made to understand the relationships between heavy rainfall over the Korean Peninsula and remote tropical cyclones (TCs) with climatological and composite analysis. We examine the typhoon best track data, surface precipitation data, and reanalysis data. The statistical analysis of the period from 1980 to 2009 shows that landfalling TCs over southern and southeastern China and TCs over the eastern sea of Taiwan can induce heavy rainfall over the Korean Peninsula more frequently. In order to verify the role of remote TCs on heavy rainfall over the Korean Peninsula, composites are constructed for heavy rainfall and no rainfall environments. The composite study presents the moisture transport into the Korean Peninsula by remote TC's outer circulation and large-scale environments affects heavy rainfall over the Korean Peninsula.
