摘    要:通过求解海冷水团叶绿素一维模式控制方程,首次对风搅拌混合、潮混合和光衰减强度的影响机制进行了解析研究。结果表明,湍流湿合过程和光的衰减强度对叶绿素夏季垂向分布结构具有重要影响。增强海面风搅拌合作用的结果,导致叶绿素表层分布趋于均匀;增强潮温合,导致叶绿素最大值增加,最大值的位置向海面抬升;减少光的衰减强度,导致叶绿素最大值增加,最大值的位置下沉。

关 键 词:黄海冷水团  叶绿素  影响机制

Abstract:This paper deals with the effect mechanisms on chlorophyll a vertical distribution during the summer months. The relative importance of various environmental factors such as light, stratified waters and turbulence mixing process are discussed in this paper. The degree of vertical turbulent mixing, which largely determines the inorganic nutrients for phytoplankton growth, can be defined in terms of wind and tide. The theoretical approach indicates that when the wind increased, the homogeneous layer of chlorophyll a in the upper seawaters will be increased. While when the tidal mixing becomes stronger, the maximum value of chlorophyll a will be increased and the maximum position will be shoaled. The light, on the other way, is the more effective factor on chlorophyll a vertical distribution. When the extinction coefficient increase, the maximum value of chlorophyll a will be decreased and the maximum position will be also shoaled.
Keywords:Yellow Sea Cold Water Mass    Chlorophyll    a      Effect mechanism
