A set of field measurements of air turbulence above an outdoor urban scale model and a rice paddy field was conducted. This study was aimed to find out the differences between turbulent statistics over urban-like canopy and those over vegetation canopy. Momentum roughness of the rice paddy field was larger than that of the urban scale model. This is probably due to the large frontal area index of the paddy field. Quadrant analyses indicate that momentum is efficiently transferred by turbulence on the paddy field. Spectral analyses also indicate that the momentum is efficiently transferred at a specific frequency.
