A Study of Hail Growth Utilizing Observed Storm Conditions
Publisher: American Meteorological Society
Abstract: Hail growth is studied in the Westplains, Colorado, storm for which a variety of observations were collected. Measurements from a triple-Doppler radar network and a penetrating aircraft are used to synthesize fields of ...
Variance Spectrum Analysis of Doppler Radar Observations in Continuous Precipitation
Publisher: American Meteorological Society
Abstract: A continuous record of precipitation falling through a fixed volume in space was obtained by means of a vertically-pointing pulsed-Doppler radar during a period of continuous precipitation. The range gate was held fixed ...
Determination of the Boundary Layer Airflow from a Single Doppler Radar
Publisher: American Meteorological Society
Abstract: In the warm season the optically clear boundary layer often contains scatterers that can be detected by sensitive radars to distances of 50?100 km. Inhomogeneities in the field of reflectivity lead to echo patterns that ...
Case Study of a Hailstorm in Colorado. Part III: Airflow From Triple-Doppler Measurements
Publisher: American Meteorological Society
Abstract: Triple-Doppler measurements are presented for a hailstorm of moderate intensity that occurred over the High plains of northeastern Colorado, and an airflow model is synthesized. The storm had a number of persistent features ...
Case Study of a Hailstorm in Colorado. Part I: Radar Echo Structure and Evolution
Publisher: American Meteorological Society
Abstract: A detailed description is given of the morphology and evolution of a moderate hailstorm in terms primarily of quantitative S-band reflectivity factor measurements. During the early phase of the storm's life its movement ...
Results of a Randomized Hail Suppression Experiment in Northeast Colorado. Part I: Design and Conduct of the Experiment
Publisher: American Meteorological Society
Abstract: The results of a three-year randomized seeding experiment carried out as part of the National Hail Research Experiment are described in a nine-part series. In this first part the design of the statistical experiment is ...
Results of a Randomized Hail Suppression Experiment in Northeast Colorado. Part VI: Post Hoc Stratification by Storm Intensity and Type
Publisher: American Meteorological Society
Abstract: The surface hail and rain data collected during the randomized seeding experiment of the National Hail Research Experiment (NHRE) are stratified according to storm intensity in a search for seeding effects. The problems ...
Precipitation Production in a Large Montana Hailstorm: Airflow and Particle Growth Trajectories
Publisher: American Meteorological Society
Abstract: Computations of air motion and precipitation growth using winds derived from Doppler radar measurements were analyzed to reveal important flow features that influenced the production of precipitation during the nearly ...
