This paper discusses the adequacy of representing the constant pressure surfaces in the atmosphere by considering only two levels, 1000 mb and 500 mb. The equations of motion and the thermodynamic equation are reviewed, together with the formulation of the Sawyer-Bushby and Godson two-level models. The height data for eight standard pressure levels from 1000 mb to 100 mb for January 1956 were used to determine linear correlation among the various levels. The multiple regression equations, so determined, were tested against independent data in 1958. It is found that the two levels account for most of the contour height variance up to 300 mb. The degree of representation drops above 300 mb and is quite variable at 100 mb. The experiment suggests that two-level representation of the synoptic scale contour height patterns is adequate, up to the 300 mb level.
