Does Ocean Turbulence Peak at the Equator?: Revisited
Publisher: American Meteorological Society
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 ...
The Rapid-Sampling Vertical Profiler: An Evaluation
Publisher: American Meteorological Society
Abstract: Evaluation of the Rapid-Sampling Vertical Profiler, which was developed for sampling the hydrophysical fields in the upper ocean from a moving vessel, shows that the instrument is useful for near-microscale measurements ...
The Efficiency of Mixing in Turbulent Patches: Inferences from Direct Simulations and Microstructure Observations
Publisher: American Meteorological Society
Abstract: The time evolution of mixing in turbulent overturns is investigated using a combination of direct numerical simulations (DNS) and microstructure profiles obtained during two field experiments. The focus is on the flux ...
Turbulence and Internal Waves at the Equator. Part I: Statistics from Towed Thermistors and a Microstructure Profiler
Publisher: American Meteorological Society
Abstract: High correlations between turbulent dissipation rates and high-wavenumber internal waves and the high values of turbulent dissipation associated with internal wave activity suggest that internal waves are the main direct ...
Turbulence and Internal Waves at the Equator. Part II: Details of a Single Event
Publisher: American Meteorological Society
Abstract: In the low Richardson number shear flow above the Pacific Equatorial Undercurrent, a single vertical microstructure profile intersected the overturning crest of a packet of high horizontal wavenumber waves. The observed ...
Turbulence Decay and Restratification in the Equatorial Ocean Surface Layer following Nighttime Convection
Publisher: American Meteorological Society
Abstract: Although the process of restratification of the ocean surface layer at the equator following nighttime convection is similar in many ways to the process at midlatitudes, there are important differences. A composite day ...
Does Ocean Turbulence Peak at the Equator?
Publisher: American Meteorological Society
Abstract: A 3°N to 3°S transect of the equator at 140°15'W was made in November 1984. Vertical profiles of temperature, conductivity and turbulent dissipation were obtained at approximately 1 km intervals. Contrary to previous ...
Zonal Momentum Balance at the Equator
Publisher: American Meteorological Society
Abstract: The conventional view of equatorial dynamics requires that the zonal equatorial wind stress be balanced, in the mean, by the vertical integral of ?large-scale? terms, such as the zonal pressure gradient, mesoscale eddy ...
Internal Waves, Dynamic Instabilities, and Turbulence in the Equatorial Thermocline: An Introduction to Three Papers in this Issue
Publisher: American Meteorological Society
Abstract: Appearing in this issue of the Journal of Physical Oceanography are three papers that present new observations of a distinct, narrow band, and diurnally varying signal in temperature records obtained in the low Richardson ...
