    1. Introduction [2] The turbulent motion in the upper ocean is a highly specific example of turbulence in a liquid whose free surface is subject to wind friction. The ultimate result of this action is the formation of waves, pure drift currents, and turbulence, leading to strong vertical mixing of the upper ocean :// Southern Ocean climate change is at the heart of the ocean's response to anthropogenic forcing. Variations in South Polar atmospheric circulation patterns, fluctuations in the strength and position of the Antarctic Circumpolar Current, and the intertwining intermediate deep water cells of the oceanic meridional overturning circulation have important impacts on the rate of ocean carbon ?id=sowg.

      The paper presents formulas for the statistical moments of a plane sound wave propagating in moving random media (the turbulent atmosphere and ocean, turbulent flows of gases and fluids, etc.) with arbitrary spectra of temperature and medium velocity :// Transfer of slightly soluble gases across the air-sea interface under conditions where no significant wave breaking is occurring is considered. The flow field near the interface is described by an Orr-Sommerfeld equation with the key boundary condition being the variation in interfacial stress caused by a turbulent wind flow over small-wavelength waves.

Approved for public release; distribution al analyses are performed on turbulence data obtained over natural ocean waves during BOMEX. Results are obtained for variance and co-variance spectra, phase and coherence Abstract.

Turbulence data obtained over ocean waves during the BOMEX experiment of are presented. Procedures in measurement and analyses are described which include adjustments for possible platform, R/V FLIP, motion. Momentum transfer is shown to have been influenced by both stability and wind-wave :// Over the last two decades, it has been shown that the intensity of turbulent mixing is not uniform but strongly varies geographically.

Actually, turbulent mixing in the global ocean is thought to be dominated by breaking of tidally generated high-mode internal waves over topographic features (boundary mixing; e.g., van Haren et al. The ocean surface responds with drift currents, surface waves, and turbulent eddies over a broad range of scales.

There are other phenomena—such as bubble injection, spray ejection, rainfall, foam, and surfactants—which further affect the dynamics and complicate the :// 「Turbulence in the ocean」を図書館から検索。カーリルは複数の図書館からまとめて蔵書検索ができるサービスです。 近くの図書館から探してみよう カーリルは全国の図書館から本を検索できるサービスです This topic browser contains over terms and is organized in a three-level hierarchy.

This production of TKE is believed to occur mostly through the large shear at the forward face of breaking waves (Ardhuin and Jenkins ).

Ocean waves are ubiquitous features that cover the ocean's surface under most conditions. Surface waves range in wavelength from a few centimeters (capillary waves) to hundreds of meters (for wind waves or swell) with corresponding High- and low-pressure systems, commonly referred to as synoptic systems, are the most energetic fluctuations of wind and temperature in the midlatitude troposphere.

Synoptic systems are a few thousand kilometers in scale and are governed by a balance between the pressure gradient force and the Coriolis force. Observations collected near the tropopause by commercial aircraft indicate a change   Theories for the Synoptic-to-Mesoscale Transition.

Dewan first suggested that the mesoscale energy is dominated by a continuum of weakly nonlinear inertia–gravity dt showed that the mesoscale spectra of horizontal wind fluctuations as a function of horizontal wavenumber, vertical wavenumber, and frequency are related through the dispersion and polarization relations of inertia   The Doppler spectra of the signals of the airborne radar backscattered by the ocean water surface have been studied extensively in the past with the aim of characterizing the amplitude, period, and direction of the ocean waves.
