风生近惯性波的传播和耗散综述

The Propagation and Dissipation of Wind-Generated Near-Inertial Waves:a Review

近惯性波广泛存在于全球海洋,对海洋中的能量级联非常重要。风输入海洋的近惯性能量在海洋中是如何传播和耗散的,能量在海洋中如何划分,一直是受到高度关注的话题。本文简要综述了风生近惯性波在海洋中的传播和耗散过程,包括影响近惯性波传播的因素,比如β效应、中尺度涡度、台风尾流和近惯性波自身的波数特征等;近惯性波在风暴等强天气过程下的传播方式;近惯性波在混合层中衰减时间尺度的模拟;近惯性能量在海洋中的分配以及现有研究中还未解决的问题。本文拟为今后的近惯性波研究提供一些思路,进一步促进近惯性波机制和模拟等方面研究的深入开展。

Near-inertial waves are ubiquitous in global ocean and important for ocean energy cascade.The propagation and dissipation of wind-generated near-inertial waves,as well as their energy partition in the ocean,are of great scientific importance.This article briefly reviews the propagation and dissipation processes of wind-generated near-inertial waves in the ocean,including the factors affecting the propagation of near-inertial waves,such as theβeffect,mesoscale vorticity,typhoon wake,and the modes of near-inertial waves;the propagation of near-inertial waves under strong weather perturbations,such as storms;the simulations of the decay timescale of near-inertial waves in the mixed layer;the partition of near-inertial energy in the ocean;and the unresolved problems so far.The review is expected to provide insight for future research on mechanisms and simulations of near-inertial waves.
