摘要

摘要: 南海和阿拉伯海均位于热带的相近纬度（0°-24°N）。季风在两个海域的上层海洋环流中起到类似的作用，但是在南海和阿拉伯海之间却出现不同的叶绿素a浓度分布模式。夏季（6-8月）南海叶绿素a浓度通常低于阿拉伯海，且相对于南海来说，夏季阿拉伯海叶绿素a浓度表现出更强的年际变化。从MODIS获取的2003-2008年数据发现阿拉伯海的气溶胶光学厚度与海表面风速都相对南海更高。此外，由气溶胶光学厚度表征的尘降指数与叶绿素a浓度之间，以及风速与叶绿素a浓度之间都存在良好的相关性。这意味着海表面风和尘降从空气中、次表层或沿岸地区给阿拉伯海带来更多的营养盐，从而导致更高的叶绿素a浓度。结果表明，夏季阿拉伯海和南海表面风速与尘降在叶绿素a浓度分布上扮演了重要角色。海表面风诱发的上升流是南海西部初级生产力的影响主要因子，而气溶胶对此影响较小。

Abstract: The South China Sea (SCS) and the Arabian Sea (AS) are both located roughly in the north tropical zone with a range of similar latitude (0°-24°N). Monsoon winds play similar roles in the upper oceanic circulations of the both seas. But the distinct patterns of chlorophyll a (Chl a) concentration are observed between the SCS and the AS. The Chl a concentration in the SCS is generally lower than that in the AS in summer (June-August); the summer Chl a concentration in the AS shows stronger interannual variation, compared with that in the SCS; Moderate resolution imaging spectroradiometer (MODIS)-derived data present higher atmospheric aerosol deposition and stronger wind speed in the AS. And it has also been found that good correlations exist between the index of the dust precipitation indicated by aerosol optical thickness (AOT) and the Chl a concentration, or between wind and Chl a concentration. These imply that the wind and the dust precipitation bring more nutrients into the AS from the sky, the sub-layer or coast regions, inducing higher Chl a concentration. The results indicate that the wind velocity and the dust precipitation can play important roles in the Chl a concentration for the AS and the SCS in summer. However aerosol impact is weak on the biological productivity in the west SCS and wind-induced upwelling is the main source.
