摘要
本文利用声雷达的探测资料对大气稳定度分类进行了尝试,并与目前国内外常用的某些稳定度分类方示进行了比较。结果表明,利用声雷达记录划分的大气稳定度与双向风标的风向垂直脉动角o_(?)划分的结果比较接近。当大氯稳定度仅仅分为稳定不稳定的和中性时,声雷达所得到的分类结果与Pasqill——Turner法和o_(?)值的分类结果几乎一致。
The attempt of using acoustic radar for atmospheric stability classification was made and compared with other methods generally adopted at home and abroad. The results show that the value of atmospheric stability by using acoustic radar is quite approximate to that of wind-direction vertical fluctuation criteria σψ. when atmospheric stability is classified into stable , unstable and neutral conditions, the results of stability classitication by acoustic rader are almost the same as that of pasqill-Turner and σψ.
