摘要
利用黄海冷水团物理-生态耦合模式,对冷水团水域叶绿素垂向分布的季节变化进行了数值模拟研究。物理模式为冷水团热动力模型;生态模式主要考虑叶绿素、营养盐和食植浮游动物基本状态变量的耦合方程。研究结果表明,黄海冷水团上升流对叶绿素垂向分布的夏季上层结构具有显著影响。整个夏季,受上升流的影响,叶绿素垂向分布最大值的位置向海面抬升,量值增大,混合层叶绿素的平均浓度增加。与实测资料比较表明,考虑冷水团上升流的影响比不考虑上升流与实测结果符合要好。
Based on the physicalecological coupling model, the seasonal variations of vertical chlorophyll distribution are modeled numerically. The physical model is a thermodynamic model for the Yellow Sea Cold Water Mass, and the ecological model contains the variables of chlorophyll, nutrients and zooplankton. It is shown from the study results that the upwelling current in the Yellow Sea Cold Water Mass has a significant effect on the vertical chlorophyll distribution structure in the upper ocean in summer, the position of the vertical chlorophyll maximum rises towards the sea surface, its maximum value increases, and the mean chlorophyll concentration in the mixing layer increases due to the effect of upwelling current in the summer season. It is shown from the comparison with the observed data that the modeling results considering the effect of upwelling current are more consistent with the observed data than those considering no effect of upwelling current.
