山背波:对飞机的潜在威胁
Mountain lee waves as a latent menace to aircraft
  
中文摘要:
      山背波河飞机的潜在威胁现已毋庸置疑.为了提高在这方面作出更确切判断的能力并能进一步找出实践中可行的相应措施,首要的问题就是必须对山背波本身有足够的认识,而这正是当前国内文献中极为薄弱的环节.有鉴于此,本文系统地、较全面地介绍了山背波这种独特的次声波,对其发生机理和基本特征、以及作为其直接衍生物的相关云相和晴空湍流──—后者正是对飞机的主要潜在威胁所在──—作出简明扼要的评述.
英文摘要:
      Now there is no doubt that the mountain lee waves is a latent menace to aircraft. What of the first importance for enhancing the capacity of more exact judgement in this aspect and for attaining appropriate measures feasible in practice is the sufficient understanding of the mountain lee waves itself, but this is just the vulnerable spot in domestic literatures at present. In view of this fact, this pa per makes a systematic and relatively comprehensive introduction to the waves of interest, a distinctive kind of infrasonic waves, and gives a concise review of the mechanism of generation and fundamental characteristics of such waves as well as their direct derivants, the related cloud patterns and the clear air turbulence (CAT), where the chief latent menace to aircraft hides.
