[ncl-talk] nighttime zero cape from skewT_PlotData ?

[xiaoming Hu]

I got 0 cape from skewT_PlotData   always during nighttime. see: http://www.caps.ou.edu/micronet/WRF-UCM/FocusON_OKC/WRFV3.7.1/with_rr_fixed/wrfNCEP_DOE2d_UCM_Snudge_WangRec53waveCU14YSUparameterp_1.2005060100/wrfout_d01_skewt_1.png      which is different from what I got from   cinfo = wrf_cape_2d(pres , tk, q, z, HGT, PSFC, True )  mcape = cinfo(0,:,:)              
Apparently wrf_cape_2d  gives non-zero values. 
Anything wrong for one of them? 
ThanksXiaoming

Xiaoming,
We've been testing "conda" as a distribution mechanism for NCL, and we have a test version of NCL that you can try using this.  Please note that this is a TEST version, as we haven't released V6.4.0 yet.  This version does have the cape_2d fix.
Here's how to get "conda"
1) Download "miniconda" from:
http://conda.pydata.org/miniconda.html

Get the Python 2.7 version and not Python 3.5.
2) Install from a UNIX terminal window by typing:
conda create --name ncl_test --channel dbrown --channel khallock ncl
This creates a conda environment called "ncl_test" in which you switch in and out of from your default version of NCL
3) To activate the "ncl_test" environment, type (from bash/sh):
source activate ncl_test
4) Test NCL by typing:
ncl -Vng4ex xy01n -clean
If you have problems with the conda version, we would like to know about this right away, as we are still testing it out.
Thanks,
--Mary
