旋转流体中惯性波的完全Hamilton形式

Complete Hamiltonian formalism for inertial waves in rotating fluids

A. A. Gelash, V. S. L'vov, V. E. Zakharov

摘要:

本文提出了旋转不可压缩流体中惯性波的完全哈密顿形式。共振三波相互作用过程-衰减不稳定性和汇合的两个波-被证明是发挥关键作用的弱非线性动力学和统计的惯性波在快速旋转的情况下。研究和讨论了哈密顿方法在惯性波理论中的应用前景。

英文摘要:

Complete Hamiltonian formalism is suggested for inertial waves in rotating incompressible fluid. Resonance three-wave interaction processes -- decay instability and confluence of two waves -- are shown to play a key role in the weakly nonlinear dynamics and statistics of inertial waves in the rapid rotation case. Future applications of the Hamiltonian approach in inertial wave theory are investigated and discussed.
