| Abstract: | In this paper, the Theory of Transient Turbulence (TTT) is applied to a 2-D local circulation model to parameterize the turbulent transport processes. Our purpose is to test the efficiency of TTT in higher dimensional model and the sensitivity of simulated results to the TTT parameters. The results show that under near-neutral and unstable situations the TTT is feasible, but the mean field and the turbulence field may hive different sensitivities to the parameters. Some modification should be given to the magnitudes of parameters suggested Stull and Driedonks (1987) for different background fields and numerical grid spaces. |
