摘要
对流边界层中,大气湍流扩散参数化将依赖于对流速度尺度W和混合层高度Zi。显然,正确估算显热通量是很重要的。本文根据实测资料,对六种估算显热通量H的方法进行了比较分析。结果表明Holtslag and Ulden(1983)提出的方法效果最好。显热通量H值从不稳定层结时的10~2量级变化到稳定层结时的-10~1量级。
In convective boundary layer, parameterization of atmospheric turbulence diffu~ sion depends on W*, scale of convective velocity and zi,height of mixing layer. Evidently, correct estam tion of sensible heat flux is a great important. Based on obeservation data, we compared and analysed six kinds of method for calculating sensible heat flux in tie paper. The results show that the method proposed by Holtslag and Ueden (1983) is the best. The ranges of value calculated the sensible hoat flux change from order of 102 order in unstable condition to 10'1 in stable condition.
