| Abstract | Abstract : Our approach to parameterization of roll vortices in a TC model resembles the superparameterization approach used to simulate cloud physics processes in general circulation models (Grabowski 2001). This methodology includes embedding a roll vortex resolving high-resolution 2-D LES model into the 3-D equation system representing a TC model. The decomposition of a 3-D equation system into two coupled equation systems for the mean flow and convective scale motions (roll vortices) is described in detail by Ginis et al. (2004) for an idealized 2-D mean flow. In this project, we extended this procedure for a general case of a 3-D TC model. The two models are coupled and explicitly solve the two-way interaction between the large-scale flow and roll vortices. The approach is schematically illustrated in Fig. 1. The 2-D LES model numerical meshes are oriented perpendicular to the direction of the mean wind flow generated by the TC model within the lowest 3 km thickness layer. The exact location of the convective meshes are determined experimentally |
