| 摘 要： | 本文给出一个应用实测风和位势场形成原始方程模式初值的方法,取质量散度垂直积分为零作为约束条件。调整实测风,消去初始风场中的重力外波。计算结果是稳定的,预报的场是光滑的。这个方法尤其适用于形成产生暴雨的次天气尺度系统的初值。

| 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. |
