[ncl-talk] problem with background on moving domain

[Wang,Yu]

Dear Mary,


Thank you so much for your help. I wondered if I could ask you another question. I have unmatching lat/lon on the left and right graphs(example attached) when I am using gsn_csm_xxxx to plot moving domains. What might be the problem for that?


Best,


Yu

Yu,

I'm looking into this and am writing a version of your script that follows the domain of your lat/lon data.

The basic issue is that each WRF output file has global attributes that define the map area of interest. This is a fixed area, that I assume is big enough to enclose the full boundary of your moving nest.

When you use wrf_xxxx plotting routines, they set the map projections based on the WRF global attributes on the file, and not based on the individual lat/lon domain.

Are you saying that you want the map to be redrawn such that the center of your storm is roughly in the center of the map? If so, then you probably don't want to use the wrf_xxxx routines for plotting.

I'm creating a version of your code that uses gsn_csm_xxxx to do the plotting and will report back when it's done.

Hello,


I am trying to make some dbz plots with multiple files of a moving domain. The contour line  seems right and moving centered on the storm but all the graphs that I created have exact same background which is not right since my domain is a moving one. What should I do I am dealing with a moving domain? Is there a certain function I should or should use? I have attached my script, hope some one could give me some help.


Thank you so much for your help.


Best,


Yu
