9401300 Price The study consists of a series of numerical experiments to study the broadening of outflows of dense water from marginal seas to adjacent oceans. The method will be to run a three-dimensional ocean model and analyze the simulated outflows that will be guided by existing observations. The model uses the hydrostatic primitive equations, with horizontal resolution of 5 km along- stream, and 2 km across-stream on a 60 x 100 grid (domain size is 300 by 200 km). Specific questions to be addressed are: (1) what processes set the range of the product water T-S characteristics in a given outflow?; (2) how does the overlying ocean circulation interact with an outflow?; and, (3) can a large scale baroclinic instability of an outflow alter the mean T-S characteristics of the product water? ***

9401300 价格 该研究由一系列数值实验组成，旨在研究浓水从边缘海到邻近海洋的流出范围扩大。 该方法将运行三维海洋模型并分析以现有观测为指导的模拟流出量。 该模型采用流体静力原方程，在 60 x 100 网格（域大小为 300 x 200 km）上水平分辨率为沿流 5 公里、横流 2 公里。 需要解决的具体问题是：（1）什么过程设定了给定出水量中产水 T-S 特性的范围？ (2) 上覆海洋环流如何与流出相互作用？ (3) 出流的大规模斜压不稳定性是否会改变产水的平均 T-S 特性？ ***
