Two storms from the 9 August, 1991 CaPE case were |
|
analyzed in-depth focusing on multiparameter radar |
|
signature evolution over 60 min. in coordination with 24 |
|
aircraft penetrations which provided particle image and |
|
electric field data together with vertical air motion, |
|
cloud water and other state parameters. A total of five |
|
discrete 'cells' were identified in the two storms and |
|
their life cycle fully documented, Collaboration with |
|
South Dakota School of Mines and University of Alabama at |
|
Huntsville has resulted in a full integration of aircraft |
|
image and field mill data (from SDSM&T T-28 aircraft) |
|
with vertical air motion from dual-Doppler wind synthesis |
|
(UAH). The cellular evolution starts with a warm rain |
|
phase where updrafts and a very low concentration of |
|
large drops dominate the cloud. As the supercooled drops |
|
rise in the updraft they freeze and acquire a water-coat |
|
possibly by collisions with other liquid drops. The multi- |
|
parameter radar signatures clearly identify this mixed- |
|
phase zone. The cloud thereafter gets electrified which |
|
may intensify to produce lightning depending on cloud |
|
vertical growth, and generation of updraft/ downdrafts. |
