A five-level baroclinic model for numerical prediction of height fields at 1000, 850, 700, 500, and 300 mb is developed and programmed. Several forms of the model are tested to determine the contribution of the various terms of the vorticity equation. Forecasts from three different methods are compared. The model shows utility in prognosis. Although there are individual differences among the methods, no one of the three is significantly better over the entire hemisphere on the data tested here. The writers wish to express their appreciation to Professor George Haltiner of the U. S. Naval Postgraduate School for his assistance and guidance in this investigation. Appreciation is also expressed to the personnel of the U. S. Navy Fleet Numerical Weather Facility for their cooperation during the preparation of this paper. We are especially indebted to CDR L. C. Clarke and LT G. Lawniczak for use of their solution of the omega equation, and for their assistance to us, and to LCDR M. Jane Frawley for her aid and advice in programming.
