Good Afternoon,
I am plotting 700 mb temperature advection in both the RUC and WRF outputs.
I am attempting to do so without using WRF functions as much as possible
(since I will be comparing the WRF and RUC, hence I am trying to keep as
many plotting features similar as possible, since WRF-functions cannot be
used on the RUC output).
While plotting the 700 mb temperature advection works very well in the RUC
output, the WRF introduces some strange grey shadows/smears in the filled
contours. I believe this is likely due to the smoothing option I employed.
Unfortunately, given the high resolution of the data, the other smoothing
options I have tried never could smooth the data properly (if at all). I
tried re-adjusting the wrf_smooth_2d function but it appears to not have
any effect on eliminating the smearing and changing the color table scheme
does not seem to work either. I doubt the smearing is due to the way I
overlay the figures.
I have attached the working RUC code and associated image along with the
WRF code/image that has the issue. In an attempt to be helpful, I also
ftp'd my RUC and WRF files in case someone wanted to work with the exact
files. For the WRF, I used the wrf_post file I generated from the
wrfout_to_cf script that I used to convert my height grid onto a pressure
coordinate. Perhaps this could be responsible for some of the things I
experienced as well? If anyone could identify what that smearing problem is
and kindly provide any suggestions as to how to go about eliminating it, I
would greatly appreciate it.
