摘要
在二流近似的基础上,提出了两种计算晴空大气中长波辐射传输的方法,整个长波辐射区域被分成两个宽的光谱带,它们分别对相应的宽带光学厚度和发射率作参数化处理。这两种方法,所需的计算时间很少,但有相当好的精度,因而适于在大气环流模式中进行辐射传输的计算。
Based on the two-stream approximation, two approximate calculation schemes of long-wave radiation transfer in clear atmospheres are presented, the entire infrared region from 100 to 2600 cm is divided into two broad spectral intervals, and parameterization treatments for the corresponding broad-band optical depth and emissivity are made respectively.These two computation schemes are very fast and rather accurate, so that they are suitable for the calculations of IR radiative transfer in general circulation models.
