RISA Method for Extracting Postevent Storm Tracks
Publisher: American Meteorological Society
Abstract: lthough existing algorithms for storm tracking have been designed to operate in real time, they are also commonly used to do postevent data analysis and research. Real-time algorithms cannot use information on the subsequent ...
Landsat Identification of Tornado Damage by Land Cover and an Evaluation of Damage Recovery in Forests
Publisher: American Meteorological Society
Abstract: ultispectral satellite imagery provides a spaceborne perspective on tornado damage identification; however, few studies have explored how tornadoes alter the spectral signature of different land-cover types. In part 1 of ...
Development of an Operational Convective Nowcasting Algorithm Using Raindrop Size Sorting Information from Polarimetric Radar Data
Publisher: American Meteorological Society
Abstract: AbstractRaindrop size sorting is a ubiquitous microphysical occurrence in precipitating systems. Owing to the greater terminal fall speed of larger particles, a raindrop?s fall trajectory can be sensitive to its size, and ...
The Relationship between Automated Low-Level Velocity Calculations from the WSR-88D and Maximum Tornado Intensity Determined from Damage Surveys
Publisher: American Meteorological Society
Abstract: he relationship between automated low-level velocity derived from WSR-88D severe storm algorithms and two groups of tornado intensity were evaluated using a 4-yr climatology of 1975 tornado events spawned from 1655 supercells ...
Tornado Formation and Intensity Prediction Using Polarimetric Radar Estimates of Updraft Area

Dissipation Characteristics of Tornadic Vortex Signatures Associated with Long-Duration Tornadoes
Publisher: American Meteorological Society
Abstract: Weather Surveillance Radar?1988 Doppler (WSR-88D) data from 36 tornadic supercell cases from 2012 to 2016 are investigated to identify common tornadic vortex signature (TVS) behaviors prior to tornado dissipation. Based ...
Tornado Warning Decisions Using Phased-Array Radar Data
Publisher: American Meteorological Society
Abstract: he 2012 Phased Array Radar Innovative Sensing Experiment identified how rapidly scanned full-volumetric data captured known mesoscale processes and impacted tornado-warning lead time. Twelve forecasters from nine National ...
Forecaster Performance and Workload: Does Radar Update Time Matter?
Publisher: American Meteorological Society
Abstract: mpacts of radar update time on forecasters? warning decision processes were analyzed in the 2015 Phased Array Radar Innovative Sensing Experiment. Thirty National Weather Service forecasters worked nine archived phased-array ...
Effects of City Size on Thunderstorm Evolution Revealed through a Multiradar Climatology of the Central United States
Publisher: American Meteorological Society
Abstract: AbstractFive years of 0.01° latitude ? 0.01° longitude multiradar multisensor grids of composite reflectivity and vertically integrated signals from the maximum expected size of hail (MESH) and vertically integrated liquid ...
Impacts of Phased-Array Radar Data on Forecaster Performance during Severe Hail and Wind Events
Publisher: American Meteorological Society
Abstract: he ongoing Phased Array Radar Innovative Sensing Experiment (PARISE) investigates the impacts of higher-temporal-resolution radar data on the warning decision process of NWS forecasters. Twelve NWS forecasters participated ...
