VAS Retrievals as a Source of Information for Convective Weather Forecasts: An Objective Assessment and Comparison with Other Sources of Upper-Air Observations
Publisher: American Meteorological Society
Abstract: Objective experiments have been carried out to determine which moisture and stability indices as derived from the VISSR Atmospheric Sounder (VAS) contain the greatest amount of predictive information with respect to ...
Wind Profiler Observations Preceding Outbreaks of Large Hail over Northeastern Colorado
Publisher: American Meteorological Society
Abstract: Wind profiler, rawinsonde, and surface observations of the atmosphere over northeastern Colorado during the morning hours on 44 days were compared to the severity of subsequent thunderstorm activity. On half of thes days, ...
The WSR-88D Severe Weather Potential Algorithm
Publisher: American Meteorological Society
Abstract: The WSR-88D severe weather potential (SWP) algorithm is an automated procedure for the detection of severe local storms. The algorithm identifies individual thunderstorm cells within radar imagery and, for each cell, yields ...
The Use of Volumetric Radar Reflectivity Predictors in the Development of a Second-Generation Severe Weather Potential Algorithm
Publisher: American Meteorological Society
Abstract: The operational WSR-88D Severe Weather Potential (SWP) algorithm is an automated nowcasting procedure aimed at providing guidance in the detection of severe local storms. It yields a numerical index proportional to the ...
Improving QPE and Very Short Term QPF: An Initiative for a Community-Wide Integrated Approach
Publisher: American Meteorological Society
Abstract: Accurate quantitative precipitation estimates (QPE) and very short term quantitative precipitation forecasts (VSTQPF) are critical to accurate monitoring and prediction of water-related hazards and water resources. While ...
