【 摘 要 】

Thisstudyinvestigatesthetele-connectionofthe southeastAsianmonsoonsystemsbycomparingthe summer monsoon (June to September) rainfall variability between Pakistan and south Korea. The daily data sets (1981-2014) of rainfall of Pakistan and south Korea are utilized to explore the possible link. Thedata products of the National CentersforEnvironmentalPredictionand NationalCenterforAtmosphericResearch(NCEP/NCAR) were alsoused for the understanding of the large-scale atmospheric environments. The patterns of summer monsoon rainfall on a daily basisbetweenPakistanand southKorea followedtoeachotherthroughouttheyear.Sub-seasonaldifferencesofthe summer monsoon revealed that July is the wettest month in both countries. The large-scale atmospheric environment of highergeopotentialheightrevealedthattheTibetanhighandthewesternnorthPacificsubtropicalhighareshowing positive anomalies during positive phases over south Asia and east Asia,respectively. The anomalies of zonal wind are negative during positive phase and adversein the negative phase between 20-40oN. The reduced westerly is interpreted as the seasonalvariation and moving of jet streams from the east Asian route. The Tibetan high, northwestern Pacific subtropical high and the east Asian jet stream have reliable and sufficient linkage between the Pakistan and south Korea summer monsoon system.
