中文摘要:
      本文应用考虑大气整层辐散作用的正压涡度方程,在快速电子计算机上对一个移动性系统的流型进行数值预报。结果发现系统移动速度偏慢,这种偏慢现象和正压模式所取的平均高度以及考虑控制超长波后退的方法有关。最后提出了一种经验的改进方案。
英文摘要:
      The divergent bcrotropic vorticity equation has been uscd in the 500 mb forecasts for Eurasia.The result shows that the movement of presure systems obtaincd from this model is slower than that of actual case.It is estimated that this phenomenon is firstly due to the unsuitable choise of the mean level adopted in this barotropic model,and sccondly due to the effect of the factor which controls westward movcmcnt of the ultralong waves。Finally an improved barotropic model is proposed.
