中文摘要:
      针对目前处理初始资料中存在的问题,提出了一个满足能量守恒和整层无辐散等约束条件的变分方案,并就风的调整进行了试验。结果表明,在严格满足约束条件的情况下,调整后的风及其分布比调整前改变并不大。调整值可以作为预报方程的初值。文中还针对某些参数因人、因地而取值不同的问题,提出了一个可以随流场、温度场调整的方案。
英文摘要:
      In this paper, the causes of the inconsistencies between the initial data and the prognostic model, are discussed. One of the preliminary conclusions reached is that the inconsistencies are in many cases, primarily caused by the disagreement between the assumptions (or the treatments) made in the model and the observations taken as initial values. A scheme for initialization, constrained to total energy conservation and non-divergence of the whole air column, is proposed. Finally, a scheme for choice of certain parameters, subject to the global integral constrain is suggested.
