Abstract: A method is presented for initialization the primitive equation model including real wind and height data. Vertical mean mass divergence is set to zero as a kine-matic constraint for eliminating the extra-gravity wave in the initial wind field. Errors in the real wind are altered by assuming that they effect only the divergence part of the flow. The three dimensonal consistent array of velocity components and the height are used as the initial value of the model. The numerical results appear to be better then the balance approximation. This procedure is more effective for the initializing the sub-synoptic circulation system.
