Understanding the Effect of Climate and Hydrometeorological Extremes on Natural and Human-Induced Hydrosystems
… and modified basins in the presence of changing climate and anthropogenic impacts. An enhanced understanding of the interdependence between climate forcings, human-induced interventions, and water balance in both natural and modified basins are essential for developing reliable and resilient …

Development of a Higher-Order Ice Sheet Model Using a Rescaled Coordinate System
The Intergovernmental Panel on Climate Change (IPCC) has estimated between 9 and 88 cm of sea level rise over the next hundred years. Of this, only negative 19 to 11 cm is attributed to the largest ice masses on the planet, the Antarctic and Greenland ice sheets. Over the last decade, dramatic …

Analyzing the effects of unforced natural variability and anthropogenic forcing on ENSO variability using CESM
… an important contributor to Earth’s inter-annual climate variability, with worldwide weather effects (Whetton and Rutherfurd, 1994; Hoerling and Zhong, 1997; Dai and Wigley, 2000). Understanding how ENSO may change with climate is a major challenge, given the internal variability of the system and …

Speleothem-Based Hydroclimate Reconstruction of Northeastern Mexico Across the Last Deglaciation
As anthropogenic global warming intensifies, climate models predict more frequent drought conditions across Northeastern Mexico, but regional paleoclimate data is necessary to inform the spatial extent and severity of these droughts. In this thesis, we present a centennial-scale resolution record …

Quantifying climate change impacts on future water resources and salinity transport in a high semi-arid watershed using the APEX-MODFLOW-Salt model
… desert landscapes under the influence of future climate uncertainties. This study quantifies the impact of future climate change on hydrology and salinity transport and their total watershed yield in the Gunnison River Watershed (GRW) (14,608 km2), Colorado, using the APEX-MODFLOW-Salt …

ASSESSING FOREST RESPONSES TO CLIMATE CHANGE AND RESOLVING PRODUCTIVITY MEASUREMENTS ACROSS SPATIAL SCALES
… two publications addressing the impacts of climate change on forest productivity and one exploring the relationship between three estimates of forest productivity. In the first chapter, I evaluated whether forests have responded to recent changes in climatic conditions. Through combining …

Soil-Plant-Atmosphere Coupling during Interstorm Periods
… are dependent on how vegetation responds to climate forcings. However, characterizing vegetation responses to water stress and other environmental drivers is challenging because these forcing factors are inter-related, especially on seasonal timescales. Here, newly available global mapping …

Forced and Unforced Permafrost Changes in the Northern Hemisphere during 1901-2100
… regions are very sensitive to rapid changes in climate and environment. In recent decades, there has been growing interest to better understand the permafrost degradation over the Northern Hemisphere in the context of human-induced climate change. Understanding permafrost dynamics is not only …

On the external forcing of Indian Ocean climate variability across timescales
… to understand the dynamics of external climate forcings and the nature of the climate system’s responses for improved predictability. These forcings include low-probability, high-impact events like explosive volcanic eruptions as well as the continued injection of anthropogenic …

Glacial-Interglacial Variability of Eastern Pacific Hydroclimate
… and vital agricultural industries. Modern hydroclimate in SWNA is complex as rainfall seasonality and moisture source ranges from the Mediterranean climate of California, bimodal desert southwest, monsoonal northwest Mexico, and Central American tropics, and there is a high degree of interannual …

Geochemistry of karst deposits in Borneo detailing hydroclimate variations in the Warm Pool across the late Pleistocene
… ocean-atmospheric system causes global scale climate anomalies, most evident in the El Niño-Southern Oscillation’s coupled climate feedbacks. Despite being an area of high interest, many questions still remain regarding the west Pacific warm pool’s response to external forcing, particularly …

Links between climate feedbacks and the large-scale circulation across idealized and complex climate models
… two distinct frameworks: One that uses radiative forcings and feedbacks to investigate the thermodynamics of the response, and another that uses circulation feedbacks and thermodynamic constraints to investigate the dynamics of the response. In this thesis, I aim to help bridge the gap between …

“If it happened in…” a pseudo-global warming assessment of tropical cyclone tornadoes
… is to investigate the impacts of anthropogenic climate change on the production of tornadoes by tropical cyclones (TCs) making landfall in the United States Atlantic Basin. Hurricane Ivan (2004), a prolific tropical cyclone tornado (TCT)-producing storm, is the particular case under …

Tracer-Independent Approaches to Stratosphere-Troposphere Exchange and Tropospheric Air Mass Composition
… circulation model subject to fixed present-day climate forcings. From the one-way flux distributions, we determine the mass of the stratosphere that is in transit from the tropical tropopause back to the troposphere, partitioned according to stratospheric residence time and exit location. We …
