| 摘 要： | 本文是在的基础上,对内边界处理地形的能力进行了进一步的试验,为突出其作用,改用了P坐标,内边界改为尽量逼近真实地形(水平方向)的多边形。结果表明,多边形地形的高度场比长方形地形的结果稳定得多,且有预报能力。内边界不仅有处理地形的能力,还具有不受地形高度限制的优点。

| Abstract: | The experiment of internal boundary model for topographical effect has been carried on further on the base of Ouyang's paper1]. For protruding topographical effect and approaching the real condition of the Tibetan Plateau, the P-coordinate is used.
The experiment shows, the main trough will move eastward and weaken gradully without the topographical effct. When the topographical effect exists, the weather systems will become more stable, they can be forecasted with no restriction for the height difference of the topography using the model introduced in this paper. |
