中文摘要:
      本文讨论在大范围高空温压场的斜压发展短期数值预报中考虑地形运动学边界条件的具体方法,并用张弛法计算了二个实例的高度倾向.计算结果说明在天山阿尔泰山一带地形变高在700mb上可以大到70-80米/24小时,下层更大,是需要考虑的.但是由于地面风决定的困难,还需要考虑改进模式,在高速电子数学计算机上大量试验,才能在日常预报中使用.
英文摘要:
      The computation method for the baroclinic large-scale development under the kinematic boundary condition of earth's topography is considered. Two tendency computations of development over Tienshan-Altai region are completed with relaxation technique. The results show that over Tienshan-Altai region the orographical disturbance may reach as large as 70-80m/24hr on 700mb and 100m/24hr on 900mb level. Thus the orographical influence is of importance over that area. However, owing to the difficulty in the proper selection of surface wind used in the present model, it is suggested that the boundary condition should be re-formulated.
