Long-Term Changes To The Frost-Free Season As A Function Of Climatic Continentality, Ian Blaylock
Long-Term Changes To The Frost-Free Season As A Function Of Climatic Continentality, Ian Blaylock
Mahurin Honors College Capstone Experience/Thesis Projects
The beginning, end, and length of the annual frost-free season vary considerably both spatially and temporally. The continentality of the climate of a given area has a close connection with the magnitude and nature of these variations. Long term changes in the frost-free season can be divided into three distinct phases: a lengthening of the frost-free season in the early 20th century, a shortening in the mid-20th century, and a renewed, intensified lengthening from 1970 to today. While oceanic and ultraoceanic climates experience decreased incidence of frosts relative to their continental counterparts, analysis has shown that overall 20 …
The Evaluation Of Water Quality And Weather Patterns As Indicators For Escherichia Coli In Slaters Creek Watershed In Millersville, Tennessee, Jacqueline Brown
The Evaluation Of Water Quality And Weather Patterns As Indicators For Escherichia Coli In Slaters Creek Watershed In Millersville, Tennessee, Jacqueline Brown
Mahurin Honors College Capstone Experience/Thesis Projects
Water quality sampling was conducted in conjunction with the city of Millersville, Tennessee in order to assess levels of Escherichia coli (E. coli) in Slaters Creek. The city of Millersville is under a storm water National Pollutant Discharge Elimination System (NPDES) permit that requires compliance monitoring. In the past, monitoring of E. coli has resulted in noncompliance with state water quality regulations. A water quality assessment, including E. coli and water quality parameters, was conducted to determine if E. coli levels varied between dates within the study area. Statistical methods were utilized to determine if variations existed between the sampling …
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 …
