Creator:: Smyth, W. D., Moum, J. N., Li, L., and Thorpe, S. A.
Abstract:: A new theory of shear instability in a turbulent environment is applied to eight days of velocity and density profiles from the upper-equatorial Pacific. This period featured a regular diurnal cycle of surface forcing, together with a clear response in upper-ocean mixing. During the day, a layer of stable stratification...

Abstract:: The effect of non-zero, but small, viscosity and diffusivity on the marginal stability of a stably stratified shear flow is examined by making perturbations around the neutral solution for an inviscid and non-diffusive flow. The results apply to turbulent flows in which horizontal and vertical turbulent transports of momentum and...

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...
