| Abstract | The dynamics of the convective boundary tayer (CBL) play an important role in the land-surface atmosphere interaction by controlling the transfer of the turbulent fluxes from the surface to the free atmosphere. The depth of the CBL gradually increases during the day, not only due to direct heating from the surface, but also because the surface fluxes (thermal and mechanical) provide the energy necessary for airparcels to rise, overshoot the top of the inversion and return (due to their negative buoyancy in the air above the mixed layer) entraining warm and dry air frorn aloft into the layer. The CBLdoes-not merefy grow passively in response to this turbulence but has mechanisms of interaction in the opposite direction: the entrainment flux brings drier air into the layer, changing the saturation deficit and hence modifying the partition of energy in terms of sensible and làtent heat fluxes at lhe surface. As an active link between the surface and the free atmosphere, the CBL has to be well understood and accurately represented in General Circulation Models (GCMs) if they are to provide realistic sirnulations of the climate. It is also an essential component of pollutant dispersion models (Raynor and Watson, 1991). The parameterization of the CBL in GCMs has been reviewed by-Garratt (1993) who summarized the most important components of a CBL scheme in such models as: the depth of the CBL for vertical distribution of momentum and energy; the values of the turbulent fluxes and other turbulent properties, and the role of clouds. Deardoff (1972) has discussed two contrasting methods of representing the CBL in GCMs: the multi-layer schemes where the lowest levels of the GCM vertical grid are used to describe the CBL, and the bulk layer approach which considers the entire CBL as a single layer. Although schemes of the first type are more realistic, as the parameters are represented explicity, they can consume a great deal of computer time. In contrast, bulk layer representations are simple and permit one to obtain a prognostic equation for the height of the CBL. However, they have the disadvantage ofbeing difficult to impfement in GCMs as they require the model to have a variable vertical grid spacing to be able to represent the temporal variabilityofthe CBL height. |
