Canuto (1994), among others, showed that second order turbulence closure models produce results in good agreement with LES data, so they are satisfactory for application in operational weather forecasting. On the other hand they are computationally too expensive to be implemented in operational models. Therefore lower order models are usually preferred. We compare the results obtained from the implementation of the complete second order model suggested by Canuto with the results obtained from lower order closures, namely E-ε and E-l models. The aim is to understand the limitations of this latter models and to find a suitable parameterization for the mixing length and for the dissipation equation.
