简介:一个全球海洋碳周期模型基于海洋将军发行量模型流行音乐和改进biogeochemical模型,OCMIP-2被采用在历史上观察的大气的CO2集中和不同未来情形(叫的代表性的集中小径,或RCP)下面模仿碳周期过程。在这份报纸的RCP为第五份评价报告(AR5)在气候变化(IPCC)上跟随Intergovernmental面板的设计。模型结果证明海洋从空气吸收CO2,被吸收将在四RCP下面在第21世纪继续。由空至海的CO2流动在历史的时间期间增加了并且到达的网1.87Pg/a(由碳计算了)在2005;然而,它将在第21世纪到达山峰然后减少。海洋主要专心于CO2中间的纬度,并且在赤道区域释放CO2。然而,在南极围绕天极的水流(ACC)区域,海洋将在升起的CO2集中下面从来源改变到水池,包括RCP4.5,RCP6.0,和RCP8.5。在2100,人为的碳将被搬运到40摥漠敶?桴?湥楴敲礠慥?獩爠畯桧祬?呼??湡?桴?潲敬漠???獩琠敨猠慭汬獥t
