Abstract: The possibility of extending existing techniques for turbulence parameterization in the planetary boundary layer to attitude, orography-induced turbulence events is examined. Starting from a well-tested scheme, we show ...

Abstract: This paper investigates the problem of aggregation of land surface properties in a large area comparable in size with a model grid box of a GCM. The study is based on 3D numerical results obtained for atmospheric situations ...

Abstract: In this last part, a detailed comparison of the model predictions with all the HAPEX-MOBILHY dataset available within a mesoscale subdomain is carried out. The simulation subdomain encompasses a fraction of a pine forest ...

Abstract: As a follow-up to the HAPEX-MOBILHY experiment in southwestern France, an advanced parameterization of land-surface processes has been designed. This paper and two companions report on the implementation of this new ...

Abstract: In this second part, we report on a one-day simulation with the French Weather Service limited-area model PERIDOT, including the new parameterization of land-surface energy budget. The emphasis is put on the assessment of ...

Abstract: The quasi-normal theory modified by the clipping approximation is used to construct a numerical model of vertically inhomogeneous turbulence in a Boussinesq fluid. The pressure-correlation terms are expressed according to ...

Abstract: A modification of the quasi-normal theory is proposed for the study of inhomogeneous turbulent flows. In this approximation realizability conditions for third-order correlations are enforced. These conditions are based on ...

Abstract: A high-order model is proposed for the study of the 24 h evolution of clear planetary boundary layers. The model includes the rate equations of correlations up to the third order, as required for an accurate description ...
