Abstract
Feasibility and accuracy of the dissipation methods for estimating turbulence fluxes of the momentum, sensible and latent heat are further investigated with the turbulence data acquired over the rice paddy field. The dissipation rates of the turbulence kinetic energy and that of the scalar variance are calculated through the Fourier spectrum as well as through the second-and thirdorder structure functions, and these two estimates are compared with each other. The value of the Kolmogorov constant and Obukhov-Corrsin constant are estimated by using structure functions. Validity of Taylor's frozen turbulence hypothesis and the isotropy of the turbulence field in the inertial subrange are also investigated.
