Research Flight from OUN
Pilot: Tom Root
T.O. 22:37 UT
A storm complex starts to fire up to NW at 50 nmi at Initially there is little movement of this
complex. But as it develops, and an upper-level shortwave moves across, it
starts to move towards
Take-off at was followed by a climb to the W where the storms were near the 50 nmi range marker. Peak reflectivities exceed 65 dBZ at this time. An NO test was done in the clear at using a calibration mixture that had been put into its Tedlar bag the previous day. The first cloud pass to the west at an altitude of 17 kft started at Tom did not like the way the engine was running and did a 180o turn to the left to exit the cloud. He could not get the engine into high blower. We decide to re-enter cloud at 17 kft without being in high blower, but at the data system quit. A 180o turn to the right brought him back out and was followed by descent and return-to-base. It turns out that the data system came back on during descent. The data indicate passage through several precip-free cells with cloud liquid water peaks in the 2- 3 g m-3 range as the aircraft flew homeward through the developing cells out ahead of the advancing squall line.
Outflow from the storm the aircraft was working to the W and
NW triggered some new development right over
There were many empty buffers on the 2-DC. Hail images were OK where there was hail.
