行星边界层急流结构数值分析

A NUMERICAL ANALYSIS OF THE JET STRUCTURE IN THE PLANETARY BOUNDARY LAYER

  • 摘要: 利用行星边界层初值分析方法对行星边界层内急流结构进行数值分析。根据1979年6月10日20时华南地区的地面和850mb观测资料,计算得到边界层内各个层次的风场。计算结果与实况比较一致,并且清楚地显示出急流的细致结构。

     

    Abstract: A method of initialization for the planetary boundary layer was presented to numerical analysis of the structure of PBL jet stream. Based on the surface and 850 mb level data over the southern China, by using this method, the wind fields at 50,100,300,600,900,1200,1500 m levels are calculated. It is evident that these results are close to the observatio ns and may give a more fine description of the structure of PBL jet stream. Probably this method is applicable to numerical analysis for the PBL.
