Land Use Land Cover Change Effects On Southern Great Plains Precipitation, Alexandra Caruthers
Land Use Land Cover Change Effects On Southern Great Plains Precipitation, Alexandra Caruthers
Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research
Great Plains land use has changed substantially over the last 160 years, altering the properties of the land through increased settlement and advances in irrigation. Changing the interface between the land and atmosphere has implications for the atmospheric boundary layer, the regional circulation, the local surface energy budget and resulting precipitation patterns. Land use land cover (LULC) changes are an important topic for this region due to its heavy dependence on agriculture. This study investigates differences in Southern Great Plains precipitation patterns between four LULC scenarios: the pre-settlement, 1920’s, Dust Bowl and present day eras. Using the Weather Research and …

Evaluating The Ecological Status Of The Introduced Nile Monitor (Varanus Niloticus) In Florida: Forecasting Presence And Population Expansion Using Computational Geographic Information Systems, Noah G. Cohen
HCNSO Student Theses and Dissertations
The Nile monitor (Varanus niloticus) is a large, carnivorous lizard that has become a notorious invasive species in Florida, USA. Initially released in the 1980s from the pet trade, the species has since established at least three breeding populations and spread throughout much of southern Florida. While current control efforts have failed to eradicate V. niloticus, it is important to attain a better understanding of its invasive dynamics to guide and inform better control strategies. In this study, available georeferenced records of V. niloticus in Florida were compiled and linked to a habitat classification map to evaluate ecotype preferences. Factored …
"There Is No Planet B": Frame Disputes Within The Environmental Movement Over Geoengineering, David Russell Zeller Jr.
"There Is No Planet B": Frame Disputes Within The Environmental Movement Over Geoengineering, David Russell Zeller Jr.
USF Tampa Graduate Theses and Dissertations
This dissertation examines frame disputes within the environmental movement over geoengineering proposals. Among other core framing tasks, social movement organizations must evaluate solutions and strategies for the social problems they seek to address. These framings are frequently disputed by those within the movement. Recent controversies regarding a set of climate intervention proposals commonly known as geoengineering offer the opportunity to document the ongoing construction of competing visions of environmental sustainability. The nascent quality of these proposals generate dissonant framings—episodes where organizations within the environmental movement exhibit disagreement about one or more core framing tasks—a situation Goffman referred to as a …
Impacts Of Internal Variability On Climate Trends In Large Ensemble Simulations By Two Climate Models, Christine Bloecker
Impacts Of Internal Variability On Climate Trends In Large Ensemble Simulations By Two Climate Models, Christine Bloecker
Legacy Theses & Dissertations (2009 - 2024)
Internal climate variability (ICV) can influence trends in observations and model simulations over periods spanning decades, making it difficult to quantify the response of the climate system to external forcing. We analyze two large ensembles of climate simulations from 1950-2100 by two fully coupled climate models, namely the CanESM2 and CESM1, to quantify the effects of ICV on apparent trends in annual surface air temperature (T) and precipitation (P) over different time periods and regions. In comparison with observations, the CanESM2 overestimates the global T and P trends during 1979-2014 while they fall within the ICV-induced range of the CESM1. …
Influence Of Volcanic Eruptions On Tropical Hydroclimate During The Last Millennium, Christopher Colose
Influence Of Volcanic Eruptions On Tropical Hydroclimate During The Last Millennium, Christopher Colose
Legacy Theses & Dissertations (2009 - 2024)
Volcanic eruptions exert the most important radiative forcing on Earth’s climate during the pre-industrial interval of the last millennium. In this thesis, I investigate the role of volcanic eruptions in altering tropical climate, including temperature and rainfall. I primarily use forced transient simulations of the last millennium as a tool to explore how explosive volcanic events project onto the hydrologic cycle, as well as the imprint of water isotopologues (H216O, H218O) associated with rainfall. Attention is given to the South American continent specifically (in chapter 2), and to the entire tropics (in chapter 3).
