All screenshots are from 2-17-08. Click on a pic for a larger view.
A line of thunderstorms from around Birmingham, AL to around Mobile, AL with a lone supercell out in front (near the gulf
coast, moving out of Alabama into the Florida panhandle).
Tan lines = General Thunderstorm Risk
1 Green Line = Slight
Thunderstorm Risk
2 Green Line = 5% Tornado Risk
These line are a part of the "placefiles" that can be loaded into the
program. You can clearly see the Tornado Watch box and the thunderstorm and tornado warnings.
Zoomed in on the storm out front. You can see the supercell characteristics, the inflow notch, etc.
Rotation is indicated on the radar by the green circle.
Compared with pic #2, you can see that the storm is really starting to wrap and hook even more in pic #3. Also,
notice the purple triangle. That is a TVS or a Tornado Vortex Signature. That is a strong indicator to the presence
of a tornado. Again, radar cannot verify that, the NWS needs spotters, but the tornado warning is still ongoing.
A screen shot of the Storm Relative Velocity. Where the red color hooks into the green color, that is the area of
strong rotation.
A screen shot of the storm tops. The storm's top clouds are located at 46,000 feet. Again, you can see rotation
in the hook of the storm.
One downside to GRLevel3 is it only has the ability to only work one radar at a time. But, you can see different
attributes of the same storm like this. Here is the Base Reflectivity Radar (0.50 degree tilt), the Storm Relative Velocity,
the Tops of the storm, and the Vertical Integrated Liquid. It is the same storm system from the above pictures, a little
bit later in the day.
