PI: LeggProposal Number: 9985840Diapycnal mixing at straits and sills is observed to vary significantly from one location to another. Understanding the cause of this variation is important to climate modeling. The PI hypothesizes that planetary rotation is responsible for the observed variability. Funds are provided to characterize the structures and quantify the rates responsible for mixing in rotating, hydraulically controlled flows using large eddy simulation modeling. In particular, the dependence of these characteristics on the ratio of the channel width to internal Rossby radius of deformation will be determined.

PI：Legg Proposal Number：9985840海峡和海床的潜流混合在不同的位置有很大的不同。了解这种变化的原因对气候建模很重要。圆周率假设行星自转是观测到的变化的原因。通过使用大涡模拟模型，提供资金来描述旋转、液压控制的流动中的结构特征并量化混合率。特别是，将确定这些特性对通道宽度与内部Rossby变形半径之比的依赖关系。
