Modeling the evolution of the convective planetary boundary layer ( Wangara boundary layer experiment).

Abstract

The model is used to simulate the daytime evolution of the planetary boundary layer observed on day 33 of the Wangara boundary-layer experiment. The calculated vertical profiles of the mean wind, temperature and humidity are found to be in good agreement with the observations. The calculated vertical distributions of turbulence variables, including kinetic energy, temperature variance, heat and moisture fluxes, temperature and moisture variance, molecular dissipation, and some third-order moments, compare favorably with those estimated from other numerical models, aircraft observations and laboratory experiments. -from Authors.
