The Nowcasting of Precipitation during Sydney 2000: An Appraisal of the QPF Algorithms

Pierce et al highlights the Sydney 2000 Forecast Demonstration Project (FDP) that afforded a unique opportunity to demonstrate and compare the performance of a range of nowcasting tools, including those designed for short-range quantitative precipitation nowcasting (QPN). With a few notable exceptions, nowcasting algorithms based upon the linear extrapolation of observed precipitation motion (Lagrangian persistence) were generally superior to more sophisticated, nonlinear nowcasting methods.
