# Wind Variables

By default, wind trajectories and the first set of wind slices are computed from the variables named U, V, and W while the second set of wind slices are computed from the variables named U2, V2, and W2. Other variables can be specified through the "UVW VARS" button on the control panel. When you click on this button a pop-up window appears in which you can specify the names of the variables to use for computing trajectories, the first set of wind slices, and the second set of wind slices. Just type in the new variables names. Be aware that uppercase and lowercase are significant. Be sure you enter valid names otherwise vis5d may not compute the graphic you select.

When multiple data sets are being viewed in one display a period and data context index number must be appended to the end of each variable to specify a data set index number. For example the first set of UVW's might be " U.0 V.0 W.0" while the second set might be "U.2 V.2 W.2". The wind variables belonging to a set MUST be from the same data set other wise they will be considered invalid.

After you've entered new wind component variable names click on APPLY to use the new values but keep the window visible. Click on OK to use the new values and close the window. Click on CANCEL to discard your changes and close the window.

You can also specify the wind component variables on the command line when you start vis5d. See section 6.1 .
