A Real-Time Algorithm for the Correction of Brightband Effects in Radar-Derived QPE
Publisher: American Meteorological Society
Abstract: The bright band (BB) is a layer of enhanced reflectivity due to melting of aggregated snow and ice crystals. The locally high reflectivity causes significant overestimation in radar precipitation estimates if an appropriate ...
A Physically Based Two-Dimensional Seamless Reflectivity Mosaic for Radar QPE in the MRMS System
Publisher: American Meteorological Society
Abstract: he U.S. Weather Surveillance Radar-1988 Doppler (WSR-88D) network has provided meteorologists and hydrologists with quantitative precipitation observations at an unprecedented high spatial?temporal resolution since its ...
Correction of Radar QPE Errors Associated with Low and Partially Observed Brightband Layers
Publisher: American Meteorological Society
Abstract: he melting of aggregated snow/crystals often results in an enhancement of the reflectivity observed by weather radars, and this is commonly referenced as the bright band (BB). The locally high reflectivity often causes ...
Significant Impacts of Rainfall Redistribution through the Roof of Buildings on Urban Hydrology
Publisher: American Meteorological Society
Characterizing Spatiotemporal Variations of Hourly Rainfall by Gauge and Radar in the Mountainous Three Gorges Region
Publisher: American Meteorological Society
Abstract: nderstanding spatiotemporal rainfall patterns in mountainous areas is of great importance for prevention of natural disasters such as flash floods and landslides. There is little knowledge about rainfall variability over ...
A Real-Time Automated Quality Control of Hourly Rain Gauge Data Based on Multiple Sensors in MRMS System
Publisher: American Meteorological Society
Abstract: utomated rain gauge networks provide direct measurements of precipitation and have been used for numerous applications, such as generating regional and national precipitation maps, calibrating remote sensing quantitative ...
Improving WSR-88D Radar QPE for Orographic Precipitation Using Profiler Observations
Publisher: American Meteorological Society
Abstract: uantitative precipitation estimation (QPE) in the West Coast region of the United States has been a big challenge for Weather Surveillance Radar-1988 Doppler (WSR-88D) because of severe blockages caused by the complex ...
A Real-Time Algorithm for Merging Radar QPEs with Rain Gauge Observations and Orographic Precipitation Climatology
Publisher: American Meteorological Society
Abstract: igh-resolution, accurate quantitative precipitation estimation (QPE) is critical for monitoring and prediction of flash floods and is one of the most important drivers for hydrological forecasts. Rain gauges provide a ...
Radar-Based Quantitative Precipitation Estimation for the Cool Season in Complex Terrain: Case Studies from the NOAA Hydrometeorology Testbed
Publisher: American Meteorological Society
Abstract: his study explores error sources of the National Weather Service operational radar-based quantitative precipitation estimation (QPE) during the cool season over the complex terrain of the western United States. A new, ...
Does Subgrid Routing Information Matter for Urban Flood Forecasting? A Multiscenario Analysis at the Land Parcel Scale
