| Abstract | Simultaneous measurements of vertical velocity fluctuations, w′, and temperature fluctuations, T′, on scales of three-dimensional turbulence yield a direct measure of the turbulent heat flux, J[subscript]q. The scales contributing most significantly to J[subscript]q are tens of centimeters or about 10 times larger than the scales contributing to the turbulent kinetic energy dissipation for the data examined. A limited sample indicates that, instantaneously, J[subscript]q is almost as frequently positive (countergradient) as negative (downgradient). In contrast, instantaneous estimates of J[subscript]q from microstructure measurements of ϵ or χ are always, by definition, downgradient. |
