RISEvolution of Mesoscale Convective System Organizational Structure and Convective Line Propagation
Publisher: American Meteorological Society
Abstract: AbstractThis study examines organizational changes and periods of rapid forward propagation in an MCS on 6 July 2015 in South Dakota. The MCS case was the focus of a Plains Elevated Convection at Night (PECAN) IOP. Data ...

Dual-Wavelength Polarimetric Radar Analyses of Tornadic Debris Signatures
Publisher: American Meteorological Society
Abstract: tatistical properties of tornado debris signatures (TDSs) are investigated using S- and C-band polarimetric radar data with comparisons to damage surveys and satellite imagery. Close proximity of the radars to the 10 May ...
Kinematic and Polarimetric Radar Observations of the 10 May 2010, Moore-Choctaw Oklahoma, Tornadic Debris Signature
Publisher: American Meteorological Society
Abstract: ornadoes are capable of lofting large debris that present irregular shapes, near-random orientations, and a wide range of dielectric constants to polarimetric radars. The unique polarimetric signature associated with lofted ...
Variability of Surface Air Temperature over Gently Sloped Terrain
Publisher: American Meteorological Society
Abstract: Temperature and wind data from a rural micronet and nearby site of the Oklahoma Mesonet are analyzed to study the frequency, strength, and formation processes of cold-pool events in a region with gentle terrain. Spatial ...
A Comparison of Scan Speedup Strategies and Their Effect on Rapid-Scan Weather Radar Data Quality
Publisher: American Meteorological Society
Abstract: As the existing NEXRAD radar network nears the end of its lifecycle, intense study and planning are underway to design a viable replacement system. Ideally, such a system would offer improved temporal resolution compared ...
Orientation Analysis of Simulated Tornadic Debris
Publisher: American Meteorological Society
Abstract: AbstractPolarimetric weather radars are capable of detecting tornadic debris signatures (TDSs), which result from debris being lofted to the level of the radar beam and can be modulated by centrifuging and debris fallout. ...
The Lake Thunderbird Micronet Project
Publisher: American Meteorological Society
Abstract: The Lake Thunderbird Micronet is a dense network of environmental sensors and a meteorological tower situated on ?10 acres of rural land in central Oklahoma. The Micronet was established in the spring of 2002 as part of a ...
High-Temporal Resolution Polarimetric X-Band Doppler Radar Observations of the 20 May 2013 Moore, Oklahoma, Tornado
Publisher: American Meteorological Society
Abstract: On 20 May 2013, the cities of Newcastle, Oklahoma City, and Moore, Oklahoma, were impacted by a long-track violent tornado that was rated as an EF5 on the enhanced Fujita scale by the National Weather Service. Despite a ...
Tornado Damage Estimation Using Polarimetric Radar
Publisher: American Meteorological Society
Abstract: his study investigates the use of tornadic debris signature (TDS) parameters to estimate tornado damage severity using Norman, Oklahoma (KOUN), polarimetric radar data (polarimetric version of the Weather Surveillance ...
