Sensitivity of model output statistics on the Lorenz system
This project studies the sensitivity of model output statistics (or MOS) in numerical weather prediction to lead times and parameters. In order to study MOS in an idealized setting, I use the simplified Lorenz system of differential equations as the physical model to explore the sensitivity of …

An analysis of plutonium accountability in the COPRECAL process
… is the object of this work. A simulation model of the COPRECAL process is presented which employs state-of-the-art instrumentation to measure in-process plutonium through the simulated passage of time. Plutonium diversion schemes are incorporated into the model. After simulated thefts, …

Development of a correction approach for future precipitation changes simulated by General Circulation Models
… the coarse resolution of General Circulation Models (GCMs) and the higher-resolutions at which information is required by the majority of end users. However, the skill of GCM precipitation, particularly in simulating temporal variability, is not fully understood and statistical downscaling …

Assessment of Model Forecast Temperature Bias During Cold Air Damming in the Central Appalachian Mountains
… to both human forecasters and weather prediction models. This study explores CAD events between 2007 and 2016 archived in a Blacksburg National Weather Service ‘bust’ database – instances when forecasters erred by at least 8°F (4.4°C) on either maximum or minimum daily air temperature. The …

Improving hydrometeorologic numerical weather prediction forecast value via bias correction and ensemble analysis
… precipitation and temperature to drive reservoir models, and forecasts of temperatures to meet energy demand requirements. Extraordinary precipitation events and temperature extremes involve consequential water- and power-management decisions. This research compared weighted-average, recursive, …

Advances in statistical post-processing of weather forecasts, probabilistic forecasting, and modelling of extreme events
… ensembles of numerical weather prediction (NWP) models, which give a probabilistic estimate of future weather. However, these ensembles might have biases and errors in dispersion, thus necessitating the application of statistical corrections -- so-called statistical post-processing. In this …

General Circulation Model Regional Predictions Using MOS techniques: Seasonal Forecasting
Ocean and atmospheric Coupled Global Climate Models (CGCMs) have been widely used to provide more accurate and coherent seasonal forecasts. However, they still show some limitations. Model Output Statistics (MOS) approaches may improve performance if observed and forecast values are available for a …

Prediction of Airport Arrival Rates Using Data Mining Methods
… were discovered using various statistical modeling methods within an overarching data mining protocol and the developed models were tested using historical data. Additionally, a selected model was deployed using real-time predictive weather information to estimate airport efficiency as a …

Slot-Exchange Mechanisms and Weather-Based Rerouting within an Airspace Planning and Collaborative Decision-Making Model
We develop and evaluate two significant modeling concepts within the context of a large-scale Airspace Planning and Collaborative Decision-Making Model (APCDM) and, thereby, enhance its current functionality in support of both strategic and tactical level flight assessments. The first major concept …
