Interaction Subrange Spectra of Turbulent Wind Over an Air-Water Interface
Interaction Subrange Spectra Air-Water Interface Turbulent Win
2009/4/3
The nonlinear interaction of wave-induced air motion and the turbulent wind is examined in spectral space with the aid of a model developed through two averaging processes. The averaging periods are d...
The Spatial and Temporal Variations of the Turbulent Fluxes of Heat, Momentum and Water Vapor over Lake Ontario
Temporal Variations Water Vapor Turbulent Fluxes
2009/3/24
During the 1972 IFYGL “alert” periods, the NOAA/RFF/DC-6 gust probe instrumented aircraft was used to record time series of wind, temperature and water vapor at heights ranging from 18 to 300 m above ...
Variations of the Turbulent Fluxes of Momentum, Heat and Moisture over Lake Ontario
Turbulent Fluxes Heat Momentum Moisture Lake Ontario

During the International Field Year on the Great Lakes measurements of turbulence and turbulent fluxes were made with an instrumented jet aircraft. After removing effects of aircraft motion the fluxes...
The Rate of Dissipation of Turbulent Energy in the Upper Layer of the Ocean
Turbulent Energy Upper Layer
2009/3/24
Based on empirical data for the upper layer of the ocean, estimates of the rate of turbulent energy dissipation are obtained. The calculations of were made in four ways. The slope of the spectra E1(...
