摘要
利用一个全球海洋动力学环流模式所模拟的海洋环流场 ,建立了一个全面的二维海洋碳循环模式。此模式摒弃了传统箱模式的缺陷 ,充分考虑了诸如大气与海洋间的碳交换、光合作用和氧化分解、碳酸钙的产生和溶解、悬浮颗粒物的下沉等过程 ,尤其是在模式中耦合进了以往甚少考虑的海洋生物过程对碳循环的影响 ,引入了详尽合理的参数化方案。通过模拟发现 :在稳定状态下 ,大气和海洋中总碳含量分布依赖于发生在海洋中的各种物理化学过程及边界条件 。
A global two-dimensional (latitude×depth) model of the ocean carbon cycle, which is based on a dynamic, general circulation model of the world ocean created by Institute of Atmospheric Physics, Chinese Academy of Sciences, has been developed. The model gets rid of the shortcoming of the box model and includes the procedures such as the exchange of carbon dioxide between the atmosphere and ocean, photosynthesis and decay, calcium carbonate production and dissolution, and both kinds of suspended particles sinking into the deeper water. In particular, the effect of the ocean biota on carbon cycle is coupled into the model and the detailed and reasonable methods of parameterization is also introduced.
