Horizontal Velocity Field Overlay

Previous: HSlice Window | Up: Intro to cslice | Next: VSlice Window

By taking the Velocity Overlay choice in the Adv. Edit menu, one can access the control window for overlaying the velocity field onto the horizontal slice. The velocity overlay is drawn when the Show Arrows radio box is set.

Assuming that the velocity (u and v) units in your NetCDF file are m/s, you can think of the arrow scale representation on the screen as being cm/s, which can be scaled with the appropriate slider in the control window.
