RISSensitivity of WSR-88D Rainfall Estimates to the Rain-Rate Threshold and Rain Gauge Adjustment: A Flash Flood Case Study
Publisher: American Meteorological Society
Abstract: A strong thunderstorm produced a flash flood on the evening of 12 July 1996 in Buffalo Creek, Colorado, that caused two deaths and significant property damage. Most of the rain fell in a 1-h time period from 2000 to 2100 ...
Passive Microwave Structure of Severe Tornadic Storms on 16 November 1987
Publisher: American Meteorological Society
Abstract: Passive microwave observations using the Special Sensor Microwave/Imager are presented for severe tornadic storms in the lower midwestern United States on 16 November 1987. These measurements are compared with Geostationary ...
Comparison of High-Altitude Remote Aircraft Measurements with the Radar Structure of an Oklahoma Thunderstorm: Implications for Precipitation Estimation from Space
Publisher: American Meteorological Society
Abstract: Observations of an isolated group of Oklahoma thunderstorms from NASA's high altitude ER-2 aircraft are presented. These observations include passive radiometric measurements at frequencies in the microwave (92, 183 GHz), ...
Microphysical and Radiative Characteristics of Convective Clouds during COHMEX
Publisher: American Meteorological Society
Abstract: The use of passive remote microwave radiance measurements above cloud tops for rainrate estimation is complicated by the complex nature of cloud microphysics. The knowledge of the microphysical structure of clouds, ...
Areal Rainfall Estimates Using Differential Phase
Publisher: American Meteorological Society
Abstract: A radar polarimetric method for areal rainfall estimation is examined. In contrast to the polarimetric algorithm based on specific differential phase KDP, the proposed method does not require rain-rate estimation from KDP ...
Initiation of a Solitary Wave Family in the Demise of a Nocturnal Thunderstorm Density Current
Publisher: American Meteorological Society
Abstract: This paper describes the characteristics and evolving nature of a vigorous thunderstorm density current very early in the morning of 9 May 1981 in Oklahoma. Because the ambient lower atmosphere was stratified, interesting ...
Aircraft Overflight Measurements of Midwest Severe Storms: Implications an Geosynchronous Satellite Interpretations
Publisher: American Meteorological Society
Abstract: The instrumented NASA ER-2 aircraft overflew severe convection with infrared (IR) V features for the first time in the Midwest United States during May 1984. Measurements taken by the ER-2 were: visible and IR imagery, ...
Real-Time Adjustment of Range-Dependent Biases in WSR-88D Rainfall Estimates due to Nonuniform Vertical Profile of Reflectivity
Publisher: American Meteorological Society
Abstract: A procedure for real-time adjustment of range-dependent biases in Weather Surveillance Radar-1988 Doppler version (WSR-88D) rainfall estimates due to nonuniform vertical profile of reflectivity is proposed. Using volume-scan ...
The WSR-88D Rainfall Algorithm
Publisher: American Meteorological Society
Abstract: A detailed description of the operational WSR-88D rainfall estimation algorithm is presented. This algorithm, called the Precipitation Processing System, produces radar-derived rainfall products in real time for forecasters ...
