- A 3D display of the isosurfaces appears in the main window.
It is complex because the initial isosurface value is low, and there
are many low values in the display.
What are Radar Reflectivity Isosurfaces?
- Change the isosurface value to 50.0 dBZ
with the
Isosurface Value
slider in the control window.
- Rotate, pan, and zoom in as needed to see the new display in 3D.
- What kind of weather system produced this radar result?
What are the vertical shapes with isosurface value 50.0 dBZ?
What does this arrangement of them mean?
