Sensitivity Of Present And Future Seasonal Precipitation Over Central United States To The Representation Of Rocky Mountain Topography, 2024 University of Nebraska-Lincoln
Sensitivity Of Present And Future Seasonal Precipitation Over Central United States To The Representation Of Rocky Mountain Topography, Ranasinghe Disanayakalage Sherly Shelton Ranathunga
Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research
Precipitation change across the Central United States (USA) is of great interest to the research community. Studies using global climate simulations suggest that the “100th-Meridian”, which separates the “dry west” from the “moist east” will shift to the east as the climate responds to future emissions pathways. However, these simulations are run at relatively coarse resolutions, which do not accurately represent topography. Here, we perform regional simulations using the Weather Research and Forecasting (WRF) model to explore the sensitivity of present and future precipitation patterns across the central USA to the representation of the Rocky Mountains (RM). We …

Identifying Watershed And Climatic Factors That Influence Headwater Streams In The San Bernardino National Forest - A Framework For Adaptive Management And Conservation, Christine Sue Seeger
Electronic Theses, Projects, and Dissertations
Headwater streams play a significant role in overall watershed condition. These streams are critical freshwater resources and are imperative for human and ecosystem health. Seasonal variability in climate patterns is becoming increasingly more common as the effects of climate change are studied. The phenomenon known as “weather whiplash,” prolonged periods of drought followed by a sudden increase in precipitation, creates additional challenges for human and ecosystem conditions. Factors adversely impacting headwater streams include climate change, drought, wildfires, and human influence. While climate change continues to be studied, little is known about how weather whiplash patterns affect headwater streams in Southern …
A Multi-Metric Approach To Fay-Herriot Small Area Estimation Of Forests, 2024 University of Tennessee, Knoxville
A Multi-Metric Approach To Fay-Herriot Small Area Estimation Of Forests, Zachary Dorminey
Masters Theses
Forest managers are tasked with decisions regarding silvicultural practices that require detailed information about the environments they serve. Managing complex structures like forests demands consideration of many interrelated variables characterizing the overall condition of a forest. Success in these management initiatives includes not only maximum production from the timber assets, but also proof that these operations accord with modern sustainable practices. Small area estimates obtained from a National Forest Inventory (NFI) dataset lack necessary statistical certainty due to a relatively small sample of forest plots. These inventory datasets are spatially sparse, yet attribute-rich. Given these properties, research efforts in this …

Impact Of Rainfall On Air Temperature, Humidity And Thermal Comfort In Tropical Urban Parks, Juan A. Acero, Philip Carl Kestel, Hieu T. Dang, Leslie K. Norford
Research Collection College of Integrative Studies
Urban areas in hot and humid tropical regions are frequently exposed to uncomfortable thermal levels. A well-developed urban heat mitigation strategy is increasing vegetation infrastructure, even though the impact differs based on regional climate. In this study we have evaluated the impact of rainfall on air temperature, humidity and thermal comfort inside a large urban park in Singapore, based on measurement campaigns. A comparison between the park and an urban site is presented. Results show that rainfall significantly reduces air temperature and improves thermal comfort levels, not only right after the rain event but also in the after-event dry period. …
Modelling Postfire Recovery Of Snow Albedo And Forest Structure To Understand Drivers Of Decades Of Reduced Snow Water Storage And Advanced Snowmelt Timing, 2024 Portland State University
Modelling Postfire Recovery Of Snow Albedo And Forest Structure To Understand Drivers Of Decades Of Reduced Snow Water Storage And Advanced Snowmelt Timing, A. Surunis, K. E. Gleason
Environmental Science and Management Faculty Publications and Presentations
Forest fires darken snow albedo and degrade forest structure, ultimately reducing peak snow–water storage, and advancing snowmelt timing for up to 15 years following fire. To date, no volumetric estimates of watershed-scale postfire effects on snow–water storage and snowmelt timing have been quantified over decades of postfire recovery. Using postfire parameterizations in a spatially-distributed snow mass and energy balance model, SnowModel, we estimated postfire recovery of forest fire effects on snow–water equivalent (SWE) and snowmelt timing over decades following fire. Using this model, we quantified volumetric recovery of forest fire effects on snow hydrology across a chronosequence of eight sub-alpine …

Scaling irrigated agriculture is a global strategy to mitigate food insecurity concerns. While expanding irrigated agriculture is critical to meeting food production demands, it is important to consider how these land use and land cover changes (LULCC) may alter the water resources of landscapes and impact the spatiotemporal epidemiology of disease. Here, a generalizable method is presented to inform irrigation development decision-making aimed at increasing crop production through irrigation while simultaneously mitigating malaria risk to surrounding communities. Changes to the spatiotemporal patterns of malaria vector (Anopheles gambiae s.s.) suitability, driven by irrigated agricultural expansion, are presented for Malawi's rainy and …
Retail Investors' Activity And Climate Disasters, 2024 Singapore Management University
Retail Investors' Activity And Climate Disasters, Marinela Adriana Finta
Sim Kee Boon Institute for Financial Economics
We analyze the effects of climate disasters on retail investors’ trading activity. Results show that retail investors trade significantly less during and around climate disasters, and retail buyers exhibit higher returns than sellers. Climate disasters weaken the positive return predictability of the past month’s order imbalances while strengthening it for the past six month’s order imbalances. In the short run, firms within climate disaster counties with retail net buying underperform those with negative imbalances. Instead, in the long run, firms within and outside climate disaster counties with positive order flows outperform those with negative order flows. Finally, the estimates on …
