Here's
an image from Dallas Texas on March 19th, 2002 showing some
large cells
Its an example of the Animated beam sweep that runs during the
image analysis.
The beam isn't just "flash" but rather the pixels under the
beam are being
analyzed to determine the VIP level. Note how the thickness of
the beam
diverges with distance away from the center. This follows true
to the way the
actual NEXRAD radar beam transmits through the atmosphere, and
the
beam VIP analysis accounts for the "wider" pixels that occur
to the increased
aspect ratio at the outer radii of the beam. Click the image
for an AVI Movie
showing the beam sweep during image analysis. |

Here's
an image from Atlanta, GA on December 17th, 2001 showing a
line of
moderate precipitation moving through the area with some
embedded cells.
The DTD Tools menu is open and you can see the Radar Site
Selector showing the location of the NEXRAD image. Note also
that the upper right portion of the DTD frame shows the SCAN
STATUS. You might think that it should show "STORM DETECTED",
but that's not the case here. DTD's advanced image analysis
identified the echoes as not reaching the trigger levels set
in the Precipitation Threshold slider. Even though there are
echoes in the Personal Strom Alert Zone, they aren't enough to
trigger an alert. This is how DTD avoids false alarms. |

Here's
an animated loop from San Angelo Texas on March 19th, 2001.
This is a strong line of thunderstorms moving east of the
radar. These cells produced some large hail and several
tornado warnings. Note how additional cells are forming even
after the passage of the main squall line.
This is a perfect example of how DTD's looping capability
can show you new thunderstorm threats being generated even
after the passage of a large storm front.

Here's
an image from San Angelo Texas on March 19th, 2001 showing the
VIP Storm Cell Analyzer Window enabled.
This is a strong line of thunderstorms, and there are some
very strong embedded cells that have VIP levels in excess of
10. Watch this animated Windows AVI file showing how the VIP
analyzer allows you to determine exactly what the intensities
are.
Also note that the SCAN STATUS shows STORM DETECTED because
the VIP levels of the cells in the Personal Storm Alert Zone
met the criteria for triggering an alert. |

Here's
what the Popup Alert Window looks like when DTD has
detected a Storm Cell inside the Personal Storm Alert Zone
that meets the criteria set in the DTD Tools Menu for
Precipitation threshold and sensitivity. |
