The 3-dimensional numerical simulation of global ocean carbon cycle

First Institute of Oceanography, State Oceanic Administration, Qingdao 266061, China

摘要

摘要: 基于海洋环流模式POP和生物地球化学模型OCMIP-2,建立了全球海洋碳循环模式,并用于对全球海洋碳循环的模拟研究。该模式在大气CO₂为283×10^-6条件下,积分3 100 a,达到工业革命前的平衡态。在此基础上,用历史时期观测的大气CO₂浓度进行强迫,模拟了历史时期的海洋碳循环。模拟的无机碳浓度、总碱度与基于观测得到的结果基本一致,模式能够较好地模拟全球碳循环过程。模拟结果表明,在北半球中高纬度和南半球的中纬度,海洋是大气CO₂的主要汇区;在赤道南北纬20°之间和南大洋50°S以南,海洋表现为大气CO₂的源区。在1980s海洋吸收CO₂速率(以C计)为1.38 Pg/a,1990s为1.55 Pg/a。海洋中人为碳在北大西洋含量最大,向下到达海底并向南输运到30°N附近;在南极附近,浓度较小,深度达到3 000 m;在中纬度,人为碳被限制在温跃层以上。

Abstract: A general ocean carbon cycle model which is based on the ocean circulation model of POP and the biogeochemical model of OCMIP-2, is employed to simulate the global ocean carbon cycle. After spinning-up for 3 100 years, the model reaches the pre-industrial stable state, under the pre-industrial condition that the CO₂ concentration in atmosphere is 283×10^-6. Then the model is forced by the observed historical atmosphere CO₂ concentration. The distributions of the simulated dissolved inorganic carbon and alkalinity are consistent with the available observations. The model results show that in the mid-and high-latitude of the northern hemisphere and the mid-latitude of the southern hemisphere, ocean is the sink of CO₂, while in the equatorial area and south of 50°S, ocean is the source of CO₂. The global air-sea flux of CO₂ is 1.38 Pg/a in 1980s, while it reaches 1.55 Pg/a in 1990s. In the north Atlantic, the anthropogenic CO₂ concentration is the highest in the global ocean, and the anthropogenic CO₂ can reach the ocean deep layer and can be transported to 30°N, while in the vicinity of the Antarctic, the concentration is much lower. In the mid-latitude area, the anthropogenic carbon is trapped in the upper layer shallower than 1 000 m mainly by the thermocline and vertical mixing.
