中文摘要:
      文中用一个带生物泵的三维全球海洋碳循环模式模拟了热带太平洋表面水中CO2总量(TCO2)在El Niño和La Nina事件期间的变化。试验结果表明,西北太平洋(0~20°N,120~150°E)和赤道中东太平洋(10°S~10°N,150°E~90°W)两个海区在El Niño事件期间表面水TCO2和海气分压差(ΔPCO2)的变化十分显著。El Niño期间,西北太平洋TCO2和ΔPCO2都增加;赤道中东太平洋TCO2和ΔPCO2都减少;La Nina期间,它们的变化与El Niño期间相反。模拟的El Niño期间热带太平洋表面水中TCO2和ΔPCO2的变化趋势与观测事实吻合得较好。
英文摘要:
      The changes of total dissolved CO2 in surface water in tropical Pacific (10°S-20°N, 120°E-90°W) during El Niño and La Nina events have been numerically simulated using a three-dimensional global ocean carbon cycle model with biot a pump. The simulated results show that the changes of total dissolved CO2(TCO2) and partial pressure difference between sea and air(PCO2) in northwest Pacific(0-20°N, 120-150°E) and in central and east equatorical Pacific(10°S-10°N, 150°E-90°W) were not iceable. During El Niño events, TCO2 and PCO2 were increased in northwest Pacific and decreased in central and east Pacific; There were opposite changes in both regions during La Nina events. The simulated change trends of TCO2 and PCO2 are consistent with observations.
