Re: Re: [ncl-talk] Error in using wrf_cape_2d

Mary,

About the NCL version, I have problem in using NCL 5.2.1 or 6.0.0 because of the
old gcc version on my computer(gcc version 3.4.6, Red Hat 3.4.6-9). I have no
idea to update the gcc(the computer is not connected the internet), so I faild in
using new NCL.

My domain size is 265*265 with vertical level of 35, and the grid size is 9km. The
array type is float. And I also tried to enlarger the memory limit in the .hluresfile
(wsMaximumSize from 65113376 to 130226752, or even larger), it do not work.
