摘要

The Areal Mean Basin Estimated Rainfall (AMBER) algorithm (Davis and Jendrowski, 1996) uses United States NEXRAD (NWS's NEXt generation RADar, the NEXRAD or WSR-88D) reflectivity data to estimate average rainfall accumulations in small watersheds. Its utility has been demonstrated in the Honolulu, HI, Pittsburgh, PA, Tulsa, OK, and Sterling, VA National Weather Service Forecast Offices (NWSFOs). AMBER alerts forecasters when basins are receiving heavy amounts of rainfall relative to Flash Flood Guidance (FFG) values. The value of AMBER as a flash flood monitoring tool is limited by uncertainty in WSR-88D rainfall estimates and the applicability of county-wide or region-wide FFG values to small basins. In response to these potential shortcomings, a real-time system has been recently developed to ingest improved estimates of rainfall from the Quantitative Precipitation Estimation and Segregation Using Multiple Sensors (QPE SUMS) algorithm (Gourley et al. 2001). These accumulations are averaged in small basins (i.e., typical areas are 15 mi~2) and fed into a web-based AMBER display system called QIWI (QPE SUMS Interactive Web Interface). The QIWI interface displays average basin rainfall relative to configurable thresholds. Terrestrial parameters for each basin are listed so that the thresholds may be set appropriately. A detailed map background showing cities, topography, highways, railroads, rivers, dams, and recreational sites is also supplied. This paper demonstrates the utility of QIWI for a flash flood that occurred on July 15, 1999 in Sabino Canyon near Tucson, AZ, USA.
