T-28 Participation in the Convection and Precipitation/Electrification(CaPE)
experiment
From July 8 - Aug 18, 1991, the T-28 participated in the Convection and Precipitation/Electrification
field project in east central Florida. The experiments focused on five objectives:
- Identification of the relationships among co-evolving wind, water, and electric fields within
convective clouds.
- Determination of the meteorological and electrical conditions in which natural and triggered
lightning can (and cannot) occur, and understanding its initiation and propagation.
- Development of mesoscale numerical forecasts (2-12 hr) of wind, clouds, and thunderstorms.
- Improving techniques for performing short-period forecasts (nowcasts, < 2 hr) of convection
initiation, downbursts, and tornadoes.
- The characterization of precipitation particles and remote estimation of rainfall.
The T-28 flew to support the multiparameter radar studies and investigations of the microphysical
and electrical structure of thunderstorms, into regions of the storm where conditions precluded
other research aircraft. The T-28 was also available to supply in-situ measurements in clouds
being scanned from above by various prototype remote sensing instruments.
The standard package of instruments provided for the
determination of temperature, vertical wind, electric fields, water content, etc. During CaPE the
T-28 carried a PMS 2D-P optical probe.
