美国标准大气1976的几点分析

本文分析了美国标准大气1976的大气参数表及制定的物理假设, 其主要结果是:1.可用绝对温度来定义整个温度剖面T(Z), 而不用“分子量温度”T_M。2.温度剖面的椭圆段在110公里处引进了一个量级为10-7J/m3·s的过大散热源。3.看来大气参数表中唯一的“系统”错误是导热系数。4.详细讨论了联结均匀大气层和高层非均匀大气计算的各种可能途径。5.建议在高层大气模式中引进CO₂分量并降低计算界面到80公里。 

AN ANALYSIS OF THE U. S. STANDARD ATMOSPHERE, 1976

In this note an analysis of USSA 1976 has been made about its physical assumptions and atmospheric tables.The main results are:1.Temperature profile T(Z) may be defined with absolute temperature in full height range without using molecular-scale temperature T_M. 2.The elliptical segment of T(Z) will give a sudden heat sink of the order of 10-7J/m3.s at 110 km which is too large.3.It seems the only systematic mistake in atmospheric tables is the coefficient of thermal conductivity.4.Adetailed discussion is given about the possible choices to connect the computations of the homosphere and the upper heterosphere.5.We suggert to introduce CO₂ as a component in the upper atmosphere model and lower the computing interface down to 80 km.
