✦ Synopsis

A diagnostic modei for the determination of similarity profiles of turbulence and mean-wind gradient in the planetary boundary layer is developed. Vertical profiles of a turbulence length scale and the flux Richardson number are formulated through the extension of the relationships for the constant flux layer. These profiles together with a turbulence energy equation and a similarity profile empirically determined for heat or momentum flux are used to compute the turbulence energy. Relationships previously derived from a turbulence closure model are used to compute second moments of turbulence.

Physick et al. (1989) have discussed some difficulties associated with simulation of the sea-breeze thermal internal boundary layer (TIBL), using a numerical model containing a profile exchange coefficient formulation developed by O'Brien (1970). They suggested that a closure scheme based on a pr
