[ncl-talk] Visualization of WRF Output: Superimposition and Zooming

[Ehsan Taghizadeh]

Hi Kemal,
 
Thank you so much for sharing your script! It looks great and very well-commented, making it easier to understand its functionality. I truly appreciate the effort you've put into creating and providing this.
I'm planning to use your script to plot WRF data for my research.
Just to clarify, my main challenge involves zooming in on a specific region, superimposing three variables, and plotting the wind vector for a specific interval of grid points.
I hope it's okay to ask for a bit more guidance—specifically on how to modify the dataonmap_zoom_10.ncl script to meet these requirements. If anyone has any insights on achieving this or can suggest adjustments, that would be incredibly helpful.
Additionally, if any GeoCAT or Python scripts might suit these needs, I'd greatly appreciate your recommendations.
Any further assistance would mean a lot to me.

Hi Ehsan,
 
  
 
Try the attached ncl script to plot horizontal cross sections of several variables from your WRF output. Just read the command lines and posted comments to understand how the script operates and disregard the warnings that ncl issues. You can plot other variables by looking at the examples given in the script.
 
  
 
Kemal.

Dear NCL team,
 
  
 
I would like to plot 10 m wind vectors, 2 m temperature as contours, and topography as shaded from a WRF output file. Additionally, I need to zoom in on a domain approximately 1 × 1 degree. For instance, I would like to display one wind vector for every five grid points.
 
I reviewed the provided page (https://www.ncl.ucar.edu/Applications/wrfzoom.shtml) and tried the attached script. While it is relatively clean, it has some issues—particularly with the labels on the axes, as shown.
 
Any assistance in creating such a script would be greatly appreciated.
