I have a question about the calculation and plotting of divergence.
I used the ncl function uv2dvG to calculate divergence and everything
works well with some of my data and with NCAR_NCEP reanalysis.
However I have a problem with one diagnostic. Basicaly I calculated the
dry static energy (DSE) divergence from my model output and from NCEP
reanalysis to do a comparison. But the divergence calculated from my model
output is wrong (see figure 1b attached) while the NCEP divergence
calculated using the same procedure is good (see figure 1a).
I compared the original files by plotting (ut,vt; uz,vz) for both data set
(NCEP and CCM3) and they are comparable. I think I'm making a
mistake using uv2dvG but I don't know what.
I attached to this email the ncl programme.
I hope you will be able to help me to solve this problem.
Thanks a lot in advance,
