Analyses of interactions between the atmosphere and the continental surface in climate and weather forecast models are summarized in the paper. Phase 4 of the project, which considers the performance of land-surface schemes when coupled to selected atmospheric models, is described and preliminary results are discussed. A summary of phase 2 analyses, which compared land-surface schemes to observed fluxes and included a sensitivity analysis, is presented in some detail for background information and comparison purposes. Phase 4 is designed to develop a general coupling scheme which is able to link selected land-surface schemes to atmospheric models, to apply this to two test cases, and to analyze the results. This paper presents a method for coupling land-surface schemes to the vertical diffusion parameterization of an atmospheric model that can accommodate most numerical schemes. Implicit, semi-implicit, and explicit coupling methods are described. 18 refs., 6 figs.
