A series of experiments is described in numerical forecasting in which the wind field at mid‐tropospheric level is derived from a stream function, but the wind shear in the lower troposphere is computed in a variety of ways. The results show that the overestimation of the pressures in the region of anticyclones, which is inherent in models in which the mid‐tropospheric wind field is assumed to be geostrophic, is significantly reduced.
