上传的是NUIST卢老师的天气诊断分析课件，38页前是计算的相应内容。

求一份资料看看

啊哈

楼主应该已经解决了。附上ncep reanalysis 2 说明：
Why isn't specific humidity available with in the NCEP Reanalysis 2 dataset? How do I calculate it?
Specific humidity isn't output from the model directly. For some datasets (such as NCEP/NCAR R1) is is calculated in postprocessing but NCEP did not do this for R2. You can calculate it yourself if you download the relative humidity and temperature and use the pressure. The Clausius–Clapeyron relation allows you to calculate the saturation humidity at a specific T,p and then you use the relative humidity to get the actual humidity. NCL has a routine mixhum_ptrh that does this.
