| Research Abstract |
Flux measurement with eddy-covariance method employs the assumption of horizontally homogeneity of the fields. The effects of sudden transition from grass land to forest and of two-dimensional simple topography were investigated with wind tunnel experiment. The experiment demonstrated that the field of flow and turbulence at x<30H(H : forest canopy height) was complicated, and that advection flux was much larger than turbulent flux in the wind tunnel experiment. The effects of complex terrain on the flux measurement were examined at two flux tower sites of TKY and TKC in Gifu prefecture.
