Real Time Tornado Warning Utilizing Doppler Velocities from a Color Display.

摘要

In April to June 1977, an operational test was conducted in Oklahoma utilizing Doppler radar as the basis for real-time warning of severe weather. The Air Force Geophysics Laboratory color display was mated to the 10 cm Cimarron Doppler radar and used as warning back-up capability to the operations center at Norman. Experiences in real-time identification of mesocyclone signatures which are characteristic of severe weather are discussed. A detailed analysis of parameters associated with one tornadic mesocyclone is presented. A comparison is made between parameter values determined from the color display and from fine resolution digitized data. (Author)
