| Abstract: | In terms of the wind data measured with three-axes anemometers in Chongqing city (Dec. 16,1989-Jan. 14,1990),the turbulent characteristic vectors including the turbulent parameters, the Eulearian-time correlation, the integral time-scale of turbulence, the turbulent intensity,the friction velocity and the Reynolds stress in the surface layer have been calculated under winter light wind condition in Chongqing so as to understand the surface-layer turbulent characteristics of the city. |
