Abstract：In order to investigate the past and near future tempo-spatial distributions of surface DMS concentrations (CDMS), characteristics of change, and their influencing factors in the Yellow Sea, the CDMS in the Yellow Sea were simulated using a DMS module coupled to an ecological dynamics model of the eastern shelf seas of China. The past climate state dataset (2000~2009) and the near-future climate state dataset (2041~2050) under the RCP4.5 scenario for CORDEX-EA were used to drive the model. The results show that the annual cycle of CDMS in the Yellow Sea will change in the near future, with the months of very high CDMS shifting from May and September to April and October in the North Yellow Sea, and from April and September to April and August in the South Yellow Sea. Additionally, the local high CDMS areas will alter. The CDMS high value area is strengthened in the following areas: near the Shandong Peninsula in spring; the shallow shore in northern Jiangsu Province; the east-central South Yellow Sea in summer; and the east of the South Yellow Sea in autumn. In the summer, however, the CDMS high value area weakened near the Shandong Peninsula. The near future heat flux and wind stress have a strong influence on CDMS in the Shandong Peninsula and the central-eastern part of the South Yellow Sea; precipitation and total cloud cover have a strong influence on CDMS in the West Korea Bay; and CDMS in the shallows of northern Jiangsu Province are affected by all climate factors.
