T-28 Participation in VORTEX, 1995


The T-28 was deployed for three weeks each at Norman, Ok (May, '95) and Ft. Collins, Col (June, '95). Its mission was to penetrate convective clouds and provide in situ observations of the precipitation particle population in regions simultaneously being scanned by multi-parameter radar.

In Oklahoma the operations were in loose coordination with the Verification of Rotation in Tornadoes Experiment (VORTEX), which involved a fleet instrumented vehicles, mobile balloon launchers, and mobile surface and airborne radars. This assemblage was mobilized to intercept tornadic storms in the broad region from southern Kansas to northern Texas. The T-28, however, restricted its activities to within approximately 50 nautical miles of the radar at Cimarron, Ok.

In Colorado the T-28 performed similar service. Flights were confined to an area centered at the CSU-CHILL radar, located northeast of Greeley.

The standard package of instruments provided for the determination of temperature, vertical wind, electric fields, water content, etc. The T-28 carried a PMS 2D-P optical probe in Oklahoma and an HVPS probe in Colorado.
