The Impacts of Using Mixed Physics in the Community Leveraged Unified Ensemble

Source: Weather and Forecasting:;2019:;volume 034:;issue 004:;page 849

Author(s): Gallus, William A.; Wolff, Jamie; Gotway, John Halley; Harrold, Michelle; Blank, Lindsay; Beck, Jeff

Publisher: American Meteorological Society

Abstract: AbstractA well-known problem in high-resolution ensembles has been a lack of sufficient spread among members. Modelers often have used mixed physics to increase spread, but this can introduce problems including computational ...

Beyond the Basics: Evaluating Model-Based Precipitation Forecasts Using Traditional, Spatial, and Object-Based Methods

Source: Weather and Forecasting:;2014:;volume( 029 ):;issue: 006:;page 1451

Author(s): Wolff, Jamie K.; Harrold, Michelle; Fowler, Tressa; Gotway, John Halley; Nance, Louisa; Brown, Barbara G.

Publisher: American Meteorological Society

Abstract: hile traditional verification methods are commonly used to assess numerical model quantitative precipitation forecasts (QPFs) using a grid-to-grid approach, they generally offer little diagnostic information or reasoning ...

Abstract: his study analyzes spatial and temporal characteristics of multiyear droughts and pluvials over the southwestern United States with a focus on the upper Colorado River basin. The study uses two multiscalar moisture indices: ...

Initial Development and Testing of a Convection-Allowing Model Scorecard

Source: Bulletin of the American Meteorological Society:;2020:;volume( 100 ):;issue: 012:;page ES367

Author(s): Gallo, Burkely T.;Kalb, Christina P.;Gotway, John Halley;Fisher, Henry H.;Roberts, Brett;Jirak, Israel L.;Clark, Adam J.;Alexander, Curtis;Jensen, Tara L.

Publisher: American Meteorological Society

Abstract: Evaluation of numerical weather prediction (NWP) is critical for both forecasters and researchers. Through such evaluation, forecasters can understand the strengths and weaknesses of NWP guidance, and researchers can work ...
