| 摘 要： | 利用一个开边界北太平洋海盆尺度环流模式模拟了北太平洋CFCs的吸收和分布.模式计算了CFC_11海气界面通量及其在海洋中的输运和再分布，考察了开边界对模式模拟结果的影响以及开边界模式中不同沿等密度面扩散系数的影响.打开南边界可以很好地改善赤道以南海区的CFC_11模拟.增加沿等密度面扩散系数使得137°E和165°E断面模拟的高CFC_11水向南、向下输送的强度和影响范围都有明显增大，能很好地改善西北太平洋的模拟结果.西北太平洋是CFC_11的一个重要的汇区，此外在赤道东太平洋上升流区还存在一个小的汇区.

| Abstract: | A basin wide ocean general circulation model with open boundary is used to study the uptake and distribution of CFCs in the North Pacific. The air sea flux and the distribution of CFC 11 are computed. Based on the simulation the influences of different isopyncal diffusion coefficients and open boundary on the distribution of CFC11 are examined. Opening the southern boundary of the model can improve the simulation of CFC 11 in the area south of equator dramatically. Increasing the isopyncal diffusivity can make the water with high CFC 11 concentration at 137°E and 165°E have stronger transports southwards and downwards to cover a larger area. Increasing the isopyncal diffusivity can improve the simulated distribution of CFC 11 in the Northwest Pacific. The Northwest Pacific is an important sink of CFC 11 and there is a weak sink in the eastern equator. |
