Creator:: Nash, Jonathan D. and Moum, James N.
Abstract:: At the smallest length scales, conductivity measurements include a contribution from salinity fluctuations in the inertial–convective and viscous–diffusive ranges of the turbulent scalar variance spectrum. Interpreting these measurements is complicated because conductivity is a compound quantity of both temperature and salinity. Accurate estimates of the dissipation rate of salinity variance...

Abstract:: Direct interception of windblown cloud water by forests has been dubbed “occult deposition” because it represents a hydrological input that is hidden from rain gauges. Eddy correlation studies of this phenomenon have estimated cloud water fluxes to vegetation yet have lacked estimates of error bounds. This paper presents an evaluation...

Creator:: Herbert, D., Moum, J. N., and Caldwell, D. R.
Abstract:: In spite of the effects of several form of temporal variability that tend to mask geographical patterns in turbulence intensity, our evidence indicates that the turbulence is enhanced above the equatorial undercurrent in comparison to latitudes north and south of it. This evidence consists of three meridional transects of micro-structure...

Creator:: Smyth, William D., Hebert, D., and Moum, James N.
Abstract:: A westerly wind burst observed in the warm pool of the western equatorial Pacific Ocean cooled the ocean's surface layer by about 0.8°C. Turbulent entrainment at the base of this layer caused cooling but also heating due to the reversal of the vertical temperature gradient during rain events. Consequently, the...

Creator:: Smyth, William D., Hebert, D., and Moum, James N.
Abstract:: The dynamic response to a westerly wind burst which occurred during the Couple Ocean Atmosphere Response Experiment in the warm pool of the equatorial Pacific Ocean is described using velocity, hydrography, and microstructure measurements. Turbulent fluxes distributed momentum input from the wind over a near-surface layer of variable thickness. Coriolis...

Creator:: Smyth, W. D., Zavialov, P. O., and Moum, J. N.
Abstract:: Measurements of velocity, hydrography, surface meteorology, and microstructure were made through several squall events during a westerly wind burst that occurred in the Western Pacific warm pool in December 1992. Sustained wind forcing generated a weakly stratified turbulent surface layer that extended to the top of the main thermocline. Following...

Creator:: Miller, Robert N., Zaron, Edward D., and Bennett, Andrew F.
Abstract:: Practical hydrostatic ocean models are often restricted to statically stable configurations by the use of a convective adjustment. A common way to do this is to assign an infinite boat conductivity to the water at a given level if the water column should become statically unstable. This is implemented in...

Abstract:: The role of stratified shear instability in maintaining the deep cycle of turbulence immediately below the equatorial mixed layer is examined by means of linear stability analysis. The Taylor-Goldstein equation is solved numerically, using observed currents and stratification from the Tropical Instability Wave Experiment (TIWE). Multiple unstable modes are found,...
