Here is a vorticity advection product I created for WINGRIDDS. Key WINGRIDDS graphic feature used in making this product is the Line Based Graduated Color (CTLG) command whick will be used to show the vorticity advection. See page 154 of the WINGRIDDS Users Guide for further information on the use of the CTLG command. For this display I used the default colors for CTLG so there is no need to create a CLN* configuration file.
