0129301Carnevale"Inertially Unstable Currents and Internal Waves"In the ocean, inertial instability is thought to be the primary mechanism that maintains anticyclonic shears and vortices at stable and marginally stable values. This project will utilize a series of numerical simulations to study the evolution of inertial instability in detail. Theoretical predictions will be made for the occurrence and physical location of the instabilities initial growth from a variety of ocean models of vortices and currents. Both methods will be used to help determine the nature of the internal wave radiation that is generated by the inertial instability. Analytical and numerical work will then be undertaken to investigate the complex behavior of packets of dimensions and amplitudes consistent with the oceanic investigations.

在海洋中，惯性不稳定性被认为是维持反气旋切变和涡旋在稳定和边缘稳定值的主要机制。本项目将利用一系列数值模拟来详细研究惯性不稳定性的演化。利用各种海洋涡旋和海流模型对不稳定性初始增长的发生和物理位置进行理论预测。这两种方法都将用于帮助确定由惯性不稳定性产生的内波辐射的性质。然后将进行分析和数值工作，以研究与海洋调查一致的尺寸和振幅包的复杂行为。
