The balance wind equation is derived, analysed and programmed for application in atmospheric models, and is compared and contrasted with other wind approximations. The mathematical concept of ellipticity of the equation is related to physical characteristics of the atmosphere. A review of three different numerical methods of solution is made; after simplification, one of these is adopted. The solution is performed on the Control Data G-20 computer located at the Central Analysis Office at Montreal Airport. The computations are carried out on a 1709 point octogonal grid covering the northern hemisphere from the Pole to 15°N latitude. The two 500 mb cases selected illustrate the efficiency of the balance equation in reducing the tendency for excessive anticyclogenesis frequently displayed in geostrophic barotropic forecasts, and show that it provides a good representation of the initial wind field.
