The data of wind measurements are analyzed to yield the information of characteristics of turbulence in the rice. An exponential function is presented to express the wind profiles observed in the rice canopy. Calculations are carried out to make clear the vertical profiles of momentum flux, mixing length and turbulent transfer coefficient within the rice canopy. It is shown that the magnitude of the extinction coefficients of the respective profiles are somewhat smaller than that in a maize canopy with relatively lax leaves.
The power spectra of both horizontal and vertical components of wind are calculated above and within the rice canopy. The spectral curves of the vertical wind component are used to obtain the turbulent transfer coefficient.
