本文描述了对高空稳定大气层精细结构的研究。观测计划包括在一个穿越300米高塔的车厢上用快速响应湍流传感器进行测量，并将车厢数据与声学和雷达回声测深仪的数据进行比较。还显示了使用自由球载传感器的温度结构参数的一些支持意见。研究的层被发现是由片材和层的温度，湿度和风让人想起的片材和层结构经常报告在湖泊，河口和海洋。在温度和湿度的配置文件中的精细结构是非常高度相关的高架稳定层。这些片通常伴随着非常大的温度和湿度结构参数的薄区，显然是开尔文-亥姆霍兹不稳定性的结果，这说明了短波长雷达和声学探测器记录的这些区域的强烈回报。
Abstract A study of the finestructure within elevated stable atmospheric layers is described. The observational program consisted of measurements made with fast-response turbulence sensors on a carriage traversing a 300 m tower and comparison of the carriage data with data from acoustic and radar echo sounders. Some supporting observations using a free balloon-borne sensor of the temperature structure parameter are also shown. The layers studied were found to be composed of sheets and layers in temperature, humidity and wind reminiscent of the sheet and layer structures often reported in lakes, estuaries and the oceans. Finestructure in the profiles of temperature and humidity are very highly correlated within elevated stable layers. The sheets are generally accompanied by thin zones of very large temperature and humidity structure parameter, apparently the result of Kelvin-Helmholtz instability, that account for the strong returns from these zones recorded by short wavelength radar and acoustic sounders....
