摘要
使用CORDEX-EA过去气候态(2000-2009年)与RCP4.5情景下近未来气候态(2041-2050年)大气强迫结果驱动中国东部陆架海域耦合DMS模块生态模型,模拟了黄海过去及近未来表层DMS浓度(C_(DMS)),探究了黄海近未来C_(DMS)时空分布的变化及其影响因素.结果表明:近未来黄海C_(DMS)的年循环发生变化,北黄海C_(DMS)极高值出现月份由5、9月转变为4、10月,南黄海由4、9月转变为4、8月;局部C_(DMS)高值区也发生变化,春季山东半岛附近海域、夏季苏北浅滩、南黄海中东部、秋季南黄海东部C_(DMS)高值区加强,夏季山东半岛附近C_(DMS)高值区减弱.近未来热通量、风应力对山东半岛、南黄海中东部海域C_(DMS)影响较大;降水量、云量对西朝鲜湾C_(DMS)的影响占优;苏北浅滩C_(DMS)受多个气候因子共同作用.
In order to investigate the past and near future tempo-spatial distributions of surface DMS concentrations(C_(DMS)),characteristics of change,and their influencing factors in the Yellow Sea,the C_(DMS)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 C_(DMS)in the Yellow Sea will change in the near future,with the months of very high C_(DMS)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 C_(DMS)areas will alter.The C_(DMS)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 C_(DMS)high value area weakened near the Shandong Peninsula.The near future heat flux and wind stress have a strong influence on C_(DMS)in the Shandong Peninsula and the central-eastern part of the South Yellow Sea;precipitation and total cloud cover have a strong influence on C_(DMS)in the West Korea Bay;and C_(DMS)in the shallows of northern Jiangsu Province are affected by all climate factors.
