Graphics: NCL – Example

wrf_CrossSection4.ncl: An example script to plot data along a cross section.

In this script note:

    1. A cross section is created with a pivot point (plane) and an angle;
    2. The lines along which the cross section are plotted are also plotted on a terrain background.
    3. Data is first interpolated along this angle (to height), before plotted;
    4. Function wrf_overlays is used, as no map background information is needed;
    5. The vertical axis information is calculated.
    6. The cross sections only zoom into the first 6km.
    7. Lat and lon fields are interpolated along the cross section line (wrf_user_intrp2d).
      This information is used along the axis.
Note: Not all plots generated are depicted below.





The image above shows how a pivot point (plane) and an angle are used to create a cross section.
