Protecting The Vulnerable: Tornado Sheltering And Communication Of Public Shelters With A Case Study From The Covid-19 Pandemic, Craig Douglas Croskery

Theses and Dissertations

One of the greatest natural hazards that is faced with in much of the United States are tornadoes. Despite improvements in the warning processes, the risk of significant loss of life remains high. That is particularly true with vulnerable communities which have higher proportions of mobile homes; however, violent tornadoes are very difficult to manage in permanent homes or buildings as well. As a result, tornado shelters have been built in some communities and have become available to the public. However, their presence is intermittent, and there are many tornado-prone areas that lack such shelters.

After a public survey, it …

Analysis Of Weather-Related Flight Delays At 13 United States Airports From 2004-2019 Using A Time Series And Support Vector Regression, Caroline E. Sleeper

Theses and Dissertations

This study seeks to investigate weather-related flight delay trends at 13 United States airports. Flight delay data were collected from 2004-2019 and normalized by airport operations data. Using Support Vector Regression (SVR), visual trends were identified. Further analysis was conducted by comparing all four meteorological seasons through computing 95% bootstrap confidence intervals on their means. Finally, precipitation and snowfall data were correlated with normalized delays to investigate how they are related. This study found that the season with the highest normalized delay values is heavily dependent upon location. Most airports saw a decrease in the SVR line at some point …

Assessment Of Gnss Radio Occultation Data Assimilation In Numerical Weather Prediction Wind Forecasts, Gregory A. Egger

Theses and Dissertations

A crucial component of weather forecasting in numerical weather prediction (NWP) is the analysis of the initial state of the atmosphere. Inaccurate analysis of the environment can lead to amplifying errors in the forecast which can cause devastating effects to the population and its resources. In this study, a weather model simulation was performed over the Pacific Northwest to evaluate wind speed forecast performance by assimilating Global Navigation Satellite System (GNSS) radio occultation (RO) data. Two separate events were examined: 24 - 26 October 2021 during which a strong extratropical cyclone struck the area, and 7 - 9 November 2021 …
