The Storm Cell Identification and Tracking Algorithm: An Enhanced WSR-88D Algorithm
J. T. Johnson,Pamela L. MacKeen,Arthur Witt,E. De Wayne Mitchell,Gregory J. Stumpf,Michael D. Eilts,Kevin W. Thomas +6 more
TL;DR: The SCIT algorithm, a centroid tracking algorithm with improved methods of identifying storms (both isolated and clustered or line storms), correctly identified 68% of all cells with maximum reflectivities over 40 dB Z and 96% ofall cells withmaximum reflectivities of 50 dBZ or greater.
Journal ArticleDOI
An Enhanced Hail Detection Algorithm for the WSR-88D
Arthur Witt,Michael D. Eilts,Gregory J. Stumpf,J. T. Johnson,E. De Wayne Mitchell,Kevin W. Thomas +5 more
TL;DR: In this article, an enhanced hail detection algorithm (HDA) has been developed for the WSR-88D to replace the original hail algorithm, which estimates the probability of hail (any size), probability of severe-size hail (diameter ≥ 19 mm), and maximum expected hail size for each detected storm cell.
Journal ArticleDOI
The National Severe Storms Laboratory Mesocyclone Detection Algorithm for the WSR-88D*
Gregory J. Stumpf,Arthur Witt,E. DeWayne Mitchell,Phillip L. Spencer,James T. Johnson,Michael D. Eilts,Kevin W. Thomas,Donald W. Burgess +7 more
TL;DR: The National Severe Storms Laboratory developed a mesocyclone detection algorithm (NSSL MDA) for the Weather Surveillance Radar-1988 Doppler (WSR-88D) system designed to automatically detect and diagnose the radar radial velocity patterns associated with storm-scale (1-10-km diameter) vortices in thunderstorms.
Journal ArticleDOI
A Real-Time, Three-Dimensional, Rapidly Updating, Heterogeneous Radar Merger Technique for Reflectivity, Velocity, and Derived Products
TL;DR: A technique for taking the base radar data and derived products from multiple radars and combining them in real time into a rapidly updating 3D merged grid is described, and innovative, real-time techniques for combining velocity and velocity-derived products are demonstrated.
Journal ArticleDOI
The National Severe Storms Laboratory Tornado Detection Algorithm
E. De Wayne Mitchell,Steven V. Vasiloff,Gregory J. Stumpf,Arthur Witt,Michael D. Eilts,J. T. Johnson,Kevin W. Thomas +6 more
TL;DR: The NSSL TDA as discussed by the authors is an improvement over the current Weather Surveillance Radar-1988 Doppler (WSR-88D) Tornadic Vortex Signature Algorithm (88D TVS).
