GRLevel3 compiles the Storm Attributes window for the current site from the five raw attribute data files. Storms are ranked according to the WSR-88D specification (ICD 2620003G):
- TVS
- ETVS
- MESO
- 3D Correlated Shear
- 2D Uncorrelated Shear
- POSH
- POH
- Cell-based VIL
Storms in the window are assigned colors based on their severity: purple for storms with TVS/ETVS, red for MESO, orange for 3DC Shear, light orange for 2D Uncorrelated Shear, green for POSH >50%, light green for POSH > 30%, blue for POH >50%, and light blue for POH > 30%.
To zoom the radar display in on a particular storm cell, double-click on the cell in the attributes window. GRLevel3 will center the radar display on the storm and set the viewing radius to 40nm.
Note: clicking on the X in the window caption does not unload the Storm Attributes product, it only hides the window. To unload the Storm Attributes product, use the Products menu.
