RISHigh-Temporal-Resolution Capabilities of the National Weather Radar Testbed Phased-Array Radar
Publisher: American Meteorological Society
Abstract: Since 2007 the advancement of the National Weather Radar Testbed Phased-Array Radar (NWRT PAR) hardware and software capabilities has been supporting the implementation of high-temporal-resolution (?1 min) sampling. To ...
Rapid-Scan, Polarimetric Observations of Central Oklahoma Severe Storms on 31 May 2013
Publisher: American Meteorological Society
Abstract: n 31 May 2013, a polarimetric WSR-88D located in Norman, Oklahoma (KOUN), was used to collect sectorized volumetric observations in a tornadic supercell. Because only a fraction of the full azimuthal volume was observed, ...
Intraseasonal Variability of Summer Storms over Central Arizona during 1997 and 1999
Publisher: American Meteorological Society
Abstract: Although previous climatologies over central Arizona show a summer diurnal precipitation cycle, on any given day precipitation may differ dramatically from this climatology. The purpose of this study is to investigate the ...
Evolution of a Quasi-Linear Convective System Sampled by Phased Array Radar
Publisher: American Meteorological Society
Abstract: n 2 April 2010, a quasi-linear convective system (QLCS) moved eastward through Oklahoma during the early morning hours. Wind damage in Rush Springs, Oklahoma, approached (enhanced Fujita) EF1-scale intensity and was likely ...
Validation of Polarimetric Hail Detection
Publisher: American Meteorological Society
Abstract: This study describes, illustrates, and validates hail detection by a simplified version of the National Severe Storms Laboratory?s fuzzy logic polarimetric hydrometeor classification algorithm (HCA). The HCA uses four radar ...
A Qualitative Analysis of NWS Forecasters’ Use of Phased-Array Radar Data during Severe Hail and Wind Events
Publisher: American Meteorological Society
Abstract: he 2013 Phased Array Radar Innovative Sensing Experiment (PARISE) investigated the impacts of higher-temporal-resolution radar data on National Weather Service forecasters? warning decision processes during severe hail and ...
Exploring Applications of Eye Tracking in Operational Meteorology Research
Publisher: American Meteorological Society
Abstract: ye-tracking technology can observe where and how someone?s eye gaze is directed, and therefore provides information about one?s attention and related cognitive processes in real time. The use of eye-tracking methods is ...
Strengths and Limitations of Current Radar Systems for Two Stakeholder Groups in the Southern Plains
Publisher: American Meteorological Society
Abstract: Advancements in radar technology since the deployment of the Weather Surveillance Radar-1988 Doppler (WSR-88D) network have prompted consideration of radar replacement technologies. In order for the outcomes of advanced ...
Exploring Impacts of Rapid-Scan Radar Data on NWS Warning Decisions
Publisher: American Meteorological Society
Abstract: apid-scan weather radars, such as the S-band phased array radar at the National Weather Radar Testbed in Norman, Oklahoma, improve precision in the depiction of severe storm processes. To explore potential impacts of such ...
Considerations for Phased-Array Radar Data Use within the National Weather Service
Publisher: American Meteorological Society
Abstract: AbstractThirty National Weather Service forecasters worked with 1-, 2-, and 5-min phased-array radar (PAR) volumetric updates for a variety of weather events during the 2015 Phased Array Radar Innovative Sensing Experiment. ...
