[ncl-talk] NaN value of wrf_cape_3d function

[nafiseh pegahfar]

To whom it may concern,

I used "wrf_cape_3d" function to calculate Cape. for this aim I used 3D vand 
2D values. unfortunately in some points (based on lat/lon)  NaN value for 
cape is seen. I am sure that all data have correct units. Input values for a 
point is reported as below:

cape=9.969209968386869e+36

level=92500
TK=300.6299140816899
rv=0.008510922866573187
GPH=723.139880629395
z=0.7325572010323265
p=100078.4522848937
I think where rv value is less that 0.01, this nan value appears.
please help me to overcome to these nan values
Best Regards
