A Mass-consistent Model Applied to the Wind Field in the Upper Kitagami River Basin

Three-dimensional wind field are computed. The initial condition is givin by interpolation of the observed surface date and the gradient wind estimated from the pressure distribution, provided that the wind profile consists of the surface boundary layer, Ekman layer and free atmosphere. the optimum value of α=0.13 which is the ratio Gaussian precision moduli is determined so as that this ratio is equal to the ratio σ1/σ2, σi (i=1, 2) being deviations of the observed field from the desired adjusted field.
