印尼海浪潮流耦合数值模式的发展及其上升流模拟应用

发布时间：2021-04-17 23:39

　　印尼周边海域具有海洋生物多样性高和生产力高的特点,也是世界是重要的渔业资源区,每年出产480万吨深海鱼类。上升流区海水涌升和剧烈地垂直运动,对渔业产量有着重要的影响。精确的上升流预测能够为渔业生产和渔业资源管理提供科学的依据,帮助提高经济效益。提出一种可以表示上升流变化的简单表述,是描述上升流区域的位置和强度的迫切需要。国家海洋局海洋环境与数值模拟实验室（MASNUM）发展的三维海浪潮流耦合模式,显著提高了在中国近海的模拟性能：在马来西来海域也表现出了较好的模拟能力。本文将应用该模式模拟印度尼西亚海区的上升流。用基于垂直速度计算得到的上升流指数来表示上升流的变化,并与叶绿素a和渔业产量进行对比。数值模式因其较高的时空分辨率,为上升流指数的计算的提供了一种非常重要工具。本文中采用了并行计算的方法来提高计算效率。为检验模式的模拟性能,对模式的模拟结果与卫星观测数据和现场观测数据进行了对比；海浪模式计算的有效波高（SWH）与Jason-1卫星数据进行了比较。海浪模式在侧边界有较大的误差,并且冬季误差要大于夏季误差。模式的水平网格分辨率不够,在与观测站点对比时会产生误差；同时垂向sigma分层...
