Spatial scale data requirements using NEXRAD (WSR-88D) for accurate hydrologic prediction in urban watersheds
The deployment of the WSR-88D (NEXRAD) radar by the National Weather Service in 1992 has created the possibility for enhancing flood warning systems. Due to the improved spatial resolution of the radar, a better hydrologic prediction is possible on a real-time basis. Rainfall rates can currently be …

Operational Use of Specific Differential Phase Shift in Dual Polarization Radars
… to operational weather forecasters since the WSR-88D upgrades were completed in May 2013. Though most often used as a component in quantitative precipitation estimates, this research focused on determining if KDP is strong enough of a stand-alone product for meteorologists to use in weather …

Tropical cyclone precipitation risk in the Southern United States
… compared to hourly rainfall estimates from the WSR-88D Next Generation Weather Radar (NEXRAD-II) system. In general the synthetic TCP estimates show good agreement with radar-based observations. The rainfall algorithm appears to perform better at coastal locations versus inland ones, and in …

A GPS-IPW Based Methodology for Forecasting Heavy Rain Events
… Flood Observing and Warning System) gages, WSR-88D Doppler radar, and high precision GPS (Global Positioning System) receiver. The focus of this research is to combine the measurements from these various sensors in an algorithmic framework to determine the flash flood magnitude. It has been …

Source air feeding convection within a nocturnal mesoscale convective system during the evolution from surface-based to elevated convection
… convection. The analysis of this system uses WSR-88D composite reflectivity data, a short term forecast from the Weather Research and Forecasting (WRF) model, and back trajectories produced by the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model. This paper describes the …

A Case Study of a High-Precipitation Supercell-Bow Echo Transition on 4-5 June 2008
… and thermodynamic observations were coupled with WSR-88D radar data in an effort to diagnose key features of the SBE transition. Prior to its BE transition, the parent HP supercell produced wind gusts of over 50 knots, hail up to 2.75” in diameter, and four EF1 tornadoes. One of the …

The observed relationship between tornado intensity and pretornadic mesocyclone characteristics and environments
… from EF0 to EF5, and all were within 100 km of a WSR-88D. A key finding is that the linear regression between the mean, pre-tornadic mesocyclone width and the EF rating of the corresponding tornado yields a coefficient of determination (R2) value of 0.75. This linear relationship is the higher for …

Radar observations of misovortices within multiple long-lake-axis-parallel lake-effect bands during the OWLeS project
… Our analyses, utilizing single-Doppler WSR-88D observations and dual-Doppler wind syntheses of mobile radar data reveal that most of the wind shifts within the LLAP bands were cyclonic, but that anticyclonic shear zones and misovortices also exist. It was found that anticyclonic shear …

Electronic scan weather radar: scan strategy and signal processing for volume targets
Following the success of the WSR-88D network, considerable effort has been directed toward searching for options for the next generation of weather radar technology. With its superior capability for rapidly scanning the atmosphere, electronically scanned phased array radar (PAR) is a potential …

Analysis of vertical velocities and elevated instability in the comma-head of continental winter cyclones
… analyses from the Rapid Update Cycle model and WSR-88D data. The cyclones followed three distinct archetypical tracks and were typical of those producing winter weather in the Midwestern United States. In two of the cyclones, dry air in the middle and upper troposphere behind the Pacific cold …

Distributed Hydrologic Modeling of the Upper Roanoke River Watershed using GIS and NEXRAD
… distributed precipitation depths derived from WSR-88D next generation radar (NEXRAD) products are used as precipitation inputs. Archives of NEXRAD Stage III data are decoded, spatially and temporally registered, and verified against archived IFLOWS rain gage data. Stage III data are …
