Ocean Mixing by Kelvin-Helmholtz Instability

Creator:: Smyth, William D. and Moum, James N.
Abstract:: Kelvin-Helmholtz (KH) instability, characterized by the distinctive finite-amplitude billows it generates, is an important mechanism in the development of turbulence in the stratified interior of the ocean. In particular, it is often assumed that the onset of turbulence in internal waves begins in this way. Clear recognition of the importance...

Tracking the Strength of the Walker Circulation With Stable Isotopes in Water Vapor

Creator:: Dee, Sylvia G., Nusbaumer, Jesse, Bailey, Adriana, Russell, James M., Lee, Jung-Eun, Konecky, Bronwen, Buenning, Nikolaus H., and Noone, David C.
Abstract:: General circulation models (GCMs) predict that the global hydrological cycle will change in response to anthropogenic warming. However, these predictions remain uncertain, in particular, for precipitation (Intergovernmental Panel on Climate Change, 2013, https://doi .org/10.1017/CB09781107415324.004). Held and Soden (2006, https://doi.org/10.1175/JCLI3990.1) suggest that as lower tropospheric water vapor concentration increases in a...

Instability and hydraulics of turbulent stratified shear flows

Creator:: Liu, Zhiyu, Thorpe, S. A., and Smyth, W. D.
Abstract:: The Taylor–Goldstein (T–G) equation is extended to include the effects of small-scale turbulence represented by non-uniform vertical and horizontal eddy viscosity and diffusion coefficients. The vertical coefficients of viscosity and diffusion, A[subscript V] and K[subscript V], respectively, are assumed to be equal and are expressed in terms of the buoyancy...

Laboratory experiments on counter-propagating collisions of solitary waves. Part 1. Wave interactions

Creator:: Chen, Yongshuai and Yeh, Harry
Abstract:: Collisions of counter-propagating solitary waves are investigated experimentally. Precision measurements of water-surface profiles are made with the use of the laser induced fluorescence (LIF) technique. During the collision, the maximum wave amplitude exceeds that calculated by the superposition of the incident solitary waves, and agrees well with both the asymptotic...

Shelfbreak upwelling induced by alongshore currents: analytical and numerical results

Creator:: Miller, Robert N., Matano, Ricardo P., and Palma, Elbio D.
Abstract:: Alongshore flow in the direction of propagation of coastal trapped waves can result in upwelling at the shelfbreak. The intensity of this upwelling can be comparable in magnitude to wind-driven coastal upwelling, with its associated ecological features. Recent numerical experiments by Matano & Palma indicate that this upwelling results from...

The geography of semidiurnal mode-1 internal-tide energy loss

Creator:: Kelly, S. M., Jones, N. L., Nash, J. D., and Waterhouse, A. F.
Abstract:: The semidiurnal mode-1 internal tide receives 0.1-0.3 TW from the surface tide and is capable of propagating across ocean basins. The ultimate fate of mode-1 energy after long-distance propagation is poorly constrained by existing observations and numerical simulations. Here, global results from a two-dimensional semi-analytical model indicate that topographic scattering...

Laboratory experiments on counter-propagating collisions of solitary waves. Part 2. Flow field

Creator:: Chen, Yongshuai, Zhang, Eugene, and Yeh, Harry
Abstract:: In the companion paper (Chen & Yeh, J. Fluid Mech., vol. 749, 2014, pp. 577–596), collisions of counter-propagating solitary waves were studied experimentally by analysing the measured water-surface variations. Here we study the flow fields associated with the collisions. With the resolved velocity data obtained in the laboratory, the flow...

Tidally Driven Processes Leading to Near-Field Turbulence in a Channel at the Crest of the Mendocino Escarpment

Creator:: Musgrave, R. C., MacKinnon, J. A., Pinkel, R., Waterhouse, A. F., and Nash, J.
Abstract:: In situ observations of tidally driven turbulence were obtained in a small channel that transects the crest of the Mendocino Ridge, a site of mixed (diurnal and semidiurnal) tides. Diurnal tides are subinertial at this latitude, and once per day a trapped tide leads to large flows through the channel...

The leading edge of a tropical instability wave : interpretation as a gravity current

Creator:: McHugh, Elizabeth Helen
Abstract:: A sharp temperature front, oriented along the south-west corner of the leading edge of a Tropical Instability Wave (TIW) warm trough, was encountered at 0°N, 140°W on November 2, 2008 and detected by a 0.45°C increase in SST that occurred over 7 s. The distinct SST signal was observed at...
