Comparing and Interpreting Differently Designed Random Forests for Next-Day Severe Weather Hazard Prediction
Autor: Eric D. Loken, Adam J. Clark, Amy McGovern
Publikováno v: Weather and Forecasting. 37:871-899
Recent research has shown that random forests (RFs) can create skillful probabilistic severe weather hazard forecasts from numerical weather prediction (NWP) ensemble data. However, it remains unclear how RFs use NWP data and how predictors should be

Generating Probabilistic Next-Day Severe Weather Forecasts from Convection-Allowing Ensembles Using Random Forests
Autor: Eric D. Loken, Adam J. Clark, Christopher D. Karstens
Publikováno v: Weather and Forecasting. 35:1605-1631
Extracting explicit severe weather forecast guidance from convection-allowing ensembles (CAEs) is challenging since CAEs cannot directly simulate individual severe weather hazards. Currently, CAE-based severe weather probabilities must be inferred fr

Postprocessing Next-Day Ensemble Probabilistic Precipitation Forecasts Using Random Forests
Autor: Eric D. Loken, Kent H. Knopfmeier, Amy McGovern, Adam J. Clark, Montgomery L. Flora
Publikováno v: Weather and Forecasting. 34:2017-2044
Most ensembles suffer from underdispersion and systematic biases. One way to correct for these shortcomings is via machine learning (ML), which is advantageous due to its ability to identify and correct nonlinear biases. This study uses a single rand

Spread and Skill in Mixed- and Single-Physics Convection-Allowing Ensembles
Autor: Eric D. Loken, Adam J. Clark, Ming Xue, Fanyou Kong
Publikováno v: Weather and Forecasting. 34:305-330
Spread and skill of mixed- and single-physics convection-allowing ensemble forecasts that share the same set of perturbed initial and lateral boundary conditions are investigated at a variety of spatial scales. Forecast spread is assessed for 2-m tem

Comparison of Next-Day Probabilistic Severe Weather Forecasts from Coarse- and Fine-Resolution CAMs and a Convection-Allowing Ensemble
Autor: Ming Xue, Eric D. Loken, Fanyou Kong, Adam J. Clark
Publikováno v: Weather and Forecasting. 32:1403-1421
Given increasing computing power, an important question is whether additional computational resources would be better spent reducing the horizontal grid spacing of a convection-allowing model (CAM) or adding members to form CAM ensembles. The present

British Journal of Cancer
Background: Although the naturally occurring reovirus causes only mild symptoms in humans, it shows considerable potential as an oncolytic agent because of its innate ability to target cancer cells. In immunocompromised hosts, however, wild-type reov

Celiac Disease: Are Endomysial Antibody Test Results Being Used Appropriately?
Autor: Kelly E. McGowan, Steven D. Loken, Martha E. Lyon, J. Decker Butzner
Publikováno v: Clinical Chemistry. 53:1775-1781
Background: The aim of this study was to retrospectively examine how positive IgA-endomysial antibody (EMA) test results for celiac disease were being interpreted and acted on by physicians in the Calgary Health Region. Methods: We reviewed consecuti
