ROTATE-2003 Observations:
15 May 2003 Several, about 6, tornadoes
were intercepted in the northern Texas panhandle. At at least two
different times, two separate tornadoes were occurring in the same
supercell, and cyclic tornadogenesis was observed.
This was the first successful deployment of the
Rapid-DOW (DOW5) and it collected simultaneous multilevel data in a
tornado as it was at ranges from 2-15 km.
- DOW3 images of tornado near 22:57 UTC when Samaras in situ
probe was in/near tornado. DOW at > 10 km range and conducting
mobile survey scans, so resolution is compromized. Tick marks
are at 1 km intervals.

- Rapid-DOW images coming soon. Data were good, but we can
only playback, not translate yet.
Unlicensed chaser and research radars are Illegal and a hazard to research, destroying
data.
Marine radars are
not licensed for overland operation and should not be used by chasers
