RISTwo Case Studies of Wintertime Cloud Systems over the Colorado Rockies
Publisher: American Meteorological Society
Abstract: The economical importance of the winter snowpack to the Colorado Rocky Mountain region (e.g., weather modification potential, ski industry, avalanche prediction, snow removal, etc.) calls for an understanding of how the ...
The Application of Radar Gauge Comparisons to Operational Precipitation Profile Corrections
Publisher: American Meteorological Society
Abstract: The analyses of data recorded during the past eight years with two Swiss radars, a network of rain gauges, and river flow measurements have helped to quantify the vertical profile of reflectivity and the influences of ...
Improvement of the WSR-88D Mesocyclone Algorithm
Publisher: American Meteorological Society
Abstract: The build 9 Weather Surveillance Radar-1988/Doppler mesocyclone algorithm (B9MA) is designed to locate mesocyclones [rotating thunderstorm updrafts with diameters between 1.8 and 9.2 km (1?5 n mi)]. Because there is less ...
The Development and Verification of TIPS: An Expert System to Forecast Thunderstorm Occurrence
Publisher: American Meteorological Society
Abstract: A rule-based expert system has been developed to assist military weather forecasters in the prediction of thunderstorms. The knowledge base used by the Thunderstorm Intelligence Prediction System (TIPS) was built by using ...
Numerical Simulation of Drainage Flow in Brush Creek, Colorado
Publisher: American Meteorological Society
Abstract: One of the objectives of the Atmospheric Studies in Complex Terrain (ASCOT) program is to develop numerical models that can be used to aid in the understanding and prediction of flow patterns observed over complex terrain. ...
Flow around a Complex Building: Experimental and Large-Eddy Simulation Comparisons
Publisher: American Meteorological Society
Abstract: A field program to study atmospheric releases around a complex building was performed in the summers of 1999 and 2000. The focus of this paper is to compare field data with a large-eddy simulation (LES) code to assess the ...
Numerical Filtering of Spurious Transients in a Satellite Scanning Radiometer: Application to CERES
Publisher: American Meteorological Society
Abstract: The Clouds and Earth Radiant Energy System (CERES) scanning radiometer was designed to provide high accuracy measurements of the radiances from the earth. Calibration testing of the instruments showed the presence of an ...
Optimizing the WSR-88D Mesocyclone/Tornadic Vortex Signature Algorithm Using WATADS—A Case Study
Publisher: American Meteorological Society
Abstract: A tornado outbreak occurred in east-central Minnesota around 0000 UTC 22 July 1995, within 80 km of the KMPX WSR-88D, at the Minneapolis?Chanhassen Weather Service Forecast Office (WSFO). The WSR-88D Mesocyclone/Tornadic ...
Flow around a Complex Building: Comparisons between Experiments and a Reynolds-Averaged Navier–Stokes Approach
Publisher: American Meteorological Society
Abstract: An experiment investigating flow around a single complex building was performed in 2000. Sonic anemometers were placed around the building, and two-dimensional wind velocities were recorded. An energy-budget and wind-measuring ...
New WSR-88D Volume Coverage Pattern 12: Results of Field Tests
Publisher: American Meteorological Society
Abstract: For the first time since the installation of the national network of Weather Surveillance Radar-1988 Doppler (WSR-88D), a new scanning strategy?Volume Coverage Pattern 12 (VCP 12)?has been added to the suite of scanning ...
