Taking Action: A Case Study Analyzing The Deficiencies And Potential Opportunities For Improvement In The Severe Weather Warning System, Carson Meredith
Taking Action: A Case Study Analyzing The Deficiencies And Potential Opportunities For Improvement In The Severe Weather Warning System, Carson Meredith
Mahurin Honors College Capstone Experience/Thesis Projects
The United States is one of the most prone areas in the world to experience severe weather. A warning system operated by the National Weather Service alerts the public of the dangers of severe weather. The purpose of this project is to analyze the effectiveness of the National Weather Service warning system across Kentucky and Tennessee. A case study is presented analyzing six severe weather events in areas warned by the National Weather Service offices in Louisville, Kentucky and Nashville, Tennessee in 2018. Factors reviewed include effectiveness in issuing timely warnings, verification (i.e., whether or not severe weather actually occurred), …
Large, Long-Lived Convective Systems Over Subtropical South America And Their Relationships With Atmospheric Teleconnections, Kyle Mattingly
Large, Long-Lived Convective Systems Over Subtropical South America And Their Relationships With Atmospheric Teleconnections, Kyle Mattingly
Mahurin Honors College Capstone Experience/Thesis Projects
This study provides a climatological assessment of persistent elongated convective systems (PECS) over subtropical South America during the austral warm seasons of 1998-2007 and a comparison of PECS frequency and physical characteristics to mesoscale convective complexes (MCCs) in the region. Relationships between the Antarctic Oscillation (AAO) and El Niño – Southern Oscillation (ENSO) teleconnections and large, long-lived convective systems (LLCSs) are explored. An average of 143 PECS and 37 MCCs occurred per warm season. PECS lasted longer on average than MCCs (17 hrs. vs. 14 hrs.) and reached a greater average maximum cloud-shield extent than MCCs (297,300 km2 vs. 256,500 …
Generalized Bathtub Hazard Models For Binary-Transformed Climate Data, James Polcer
Generalized Bathtub Hazard Models For Binary-Transformed Climate Data, James Polcer
Masters Theses & Specialist Projects
In this study, we use a hazard-based modeling as an alternative statistical framework to time series methods as applied to climate data. Data collected from the Kentucky Mesonet will be used to study the distributional properties of the duration of high and low-energy wind events relative to an arbitrary threshold. Our objectiveswere to fit bathtub models proposed in literature, propose a generalized bathtub model, apply these models to Kentucky Mesonet data, and make recommendations as to feasibility of wind power generation. Using two different thresholds (1.8 and 10 mph respectively), results show that the Hjorth bathtub model consistently performed better …
