An Intercomparison Of Regional Atmospheric Circulation And The Melt Season Loss Of Arctic Snow Cover And Sea Ice Extent Across The Land–Ocean Boundary, Angela C. Bliss

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

This study is designed to compare the monthly continental snow cover and sea ice extent loss in the Arctic with regional atmospheric conditions including: mean sea level pressure, 925 hPa air temperature, and mean wind direction among others during the melt season (March-August) over the 29-year study period 1979-2007. Little research has gone into studying the concurrent variations in the annual loss of continental snow cover and sea ice extent across the land-ocean boundary, since these data are largely stored in incompatible formats. However, the analysis of these data, averaged spatially over three autonomous study regions located in Siberia, North …

Nam Model Forecasts Of Warm Season Quasi-Stationary Frontal Environments In The Central U.S., Shih-Yu (Simon) Wang, Adam J. Clark

Plants, Soils, and Climate Faculty Publications

Using a composite procedure, North American Mesoscale Model (NAM) forecast and observed environments associated with zonally oriented, quasi-stationary surface fronts for 64 cases during July–August 2006–08 were examined for a large region encompassing the central United States. NAM adequately simulated the general synoptic features associated with the frontal environments (e.g., patterns in the low-level wind fields) as well as the positions of the fronts. However, kinematic fields important to frontogenesis such as horizontal deformation and convergence were overpredicted. Surface-based convective available potential energy (CAPE) and precipitable water were also overpredicted, which was likely related to the overprediction of the kinematic …

Questions related to climate change were asked as part of New Hampshire's Granite State Poll, which surveyed 512 New Hampshire residents in April 2010.

A Planetary-Scale Land-Sea Breeze Circulation In East Asia And The Western North Pacific, W. R. Huang, J. C-L Chan, Shih-Yu (Simon) Wang

Plants, Soils, and Climate Faculty Publications

The diurnal wind variation over the East Asian continent is commonly considered to be a combination of a land-sea breeze near the coast and a mountain–valley breeze along the slopes of the Tibetan Plateau. The local land–sea breeze along the coastline typically spansHowever, a detailed examination of the global reanalysis data suggests that this local land–sea breeze circulation apparently couples with the global-scale diurnal atmospheric pressure tide to produce a planetary-scale land–sea breeze with a spatial scale of ∼1000 km over the western North Pacific. Computations of the momentum budget and equivalent potential temperatures indicate that the atmospheric diurnal tidal …

Marine Bioinvasions And Climate Change, James T. Carlton, Sandra C. Lindstrom, Celia M. Smith, Jennifer E. Smith

National Invasive Species Council

BACKGROUND

Invasive species are second only to habitat destruction as the greatest cause of species endangerment and global biodiversity loss. Invasive species can cause severe and permanent damage to the ecosystems they invade. Consequences of invasion include competition with or predation upon native species, hybridization, carrying or supporting harmful pathogens and parasites that may affect wildlife and human health, disturbing ecosystem function through alteration of food webs and nutrient recycling rates, acting as ecosystem engineers and altering habitat structure, and degradation of the aesthetic quality of our natural resources. In many cases we may not fully know the native animals …

Urban Heat Island Expansion In The Greater Las Vegas Metropolitan Area, Alex Remar

Earth and Soil Sciences

The growth of human settlements into vast urban metropolitan areas is often accompanied by relatively higher temperatures in comparison with surrounding rural countrysides, a phenomenon known as the “urban heat island effect.” The city of Las Vegas has been selected as an examination of this trend because of its unprecedented urban growth in the last 50 years, which has been mapped by satellite imagery for several decades. Studying the growth of Las Vegas’ relatively new heat island can provide valuable insight into the causes and magnitude of all urban heat islands in general.

In this investigation, a series of temperature …

Recent Advances In The Climate Change Biology Literature: Describing The Whole Elephant, A. Townsend Peterson, Shaily Menon, Xingong Li

Peer Reviewed Publications

Climate change biology is seeing a wave of new contributions, which are reviewed herein. Contributions treat shifts in phenology and distribution, and both document past and forecast future effects. However, many of the current wave of contributions are observational and correlational, and few are experimental in nature, and too often a conceptual framework in which to contextualize the results is lacking. An additional gap is the lack of effective cross-linking among areas of research, for example, connection of sea-level rise and climate change implications for distributions of species, or evolutionary adaptation studies with distributional shift studies. Although numerous important contributions …

Fire And Climate In A Lodgepole Forest Of Central Idaho: Annual, Decadal, Centennial, And Millennial Perspectives, Lar Osvard Svenson

Boise State University Theses and Dissertations

Fire history of the high-elevation forest of the Sawtooth Valley in central Idaho was reconstructed using tree rings (providing annual to decadal resolution over the past ~400 years) and radiocarbon dating of charcoal (providing centennial to millennial resolution over the past ~8000 years). Fourteen annually resolved fires were reconstructed between 1632 and 1933 AD from fire-scarred Douglas-fir (Pseudotsuga menziesii) and lodgepole pine (Pinus contorta var latifolia). Stand ages of lodgepole pine indicate that at least five annually resolved fires in the ~28,000 ha study area were stand-replacing(SR). Multi-watershed SR fires burned in 1632 and 1842, and …

Assessment Of Impacts To Hydroclimatology And River Operations Due To Climate Change Over The Colorado River Basin, William Paul Miller

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation investigated the impacts of climate change to the hydroclimatology and river and reservoir management operations within the Colorado River Basin. Preliminary research indicated observed warming trends throughout the Colorado River Basin and corresponding seasonal trends to the magnitude and timing of runoff in the Colorado River Basin. Subsequent research investigated the changing character of precipitation and corresponding impacts to streamflow over the Colorado River Basin. Analysis of snowpack telemetry (SNOTEL) stations over the American West and Colorado River Basin indicated decreasing trends in annual snowpack, often at least at the 95% confidence interval. A shorter snowpack season was …

Coherence Between The Great Salt Lake Level And The Pacific Quasi-Decadal Oscillation, Shih-Yu (Simon) Wang, Robert R. Gillies, Jiming Jin, Lawrence E. Hipps

Plants, Soils, and Climate Faculty Publications

The lake level elevation of the Great Salt Lake (GSL), a large closed basin lake in the arid western United States, is characterized by a pronounced quasi-decadal oscillation (QDO).The variation of the GSL elevation is very coherent with the QDO of sea surface temperature anomalies in the tropical central Pacific (also known as the Pacific QDO). However, such coherence denies any direct association between the precipitation in the GSL watershed and the Pacific QDO because, in a given frequency, the precipitation variation always leads the GSL elevation variation. Therefore, the precipitation variation is phase shifted from the Pacific QDO. This …

The Role Of The Alaskan Stream In Modulating The Bering Sea Climate, Tal Ezer, Lie-Yauw Oey

CCPO Publications

A numerical ocean circulation model with realistic topography, but with an idealized forcing that includes only lateral transports is used to study the role of the Alaskan Stream (AS) in modulating the Bering Sea (BS) variability. Sensitivity experiments, each one with a different strength of the AS transport reveal a nonlinear BS response. An increase of AS transport from 10 to 25 Sv causes warming (similar to 0.25 degrees C mean, similar to 0.5 degrees C maximum) and sea level rise in the BS shelf due to increased transports of warmer Pacific waters through the eastern passages of the Aleutian …

Differential Damages Sustained From Hurricane Ike On Varying Growth Forms Of Coral At Distinct Locations Off The Coast Of South Caicos, Turks And Caicos Islands, Caitlyn A. Kenny

Pell Scholars and Senior Theses

In September 2008, Hurricane Ike hit South Caicos, Turks and Caicos Islands as a Category 4 hurricane. This study examines the differential damages caused to varying common growth forms, size, locations, and depths of coral by Hurricane Ike on South Caicos reefs. Belt transect techniques as well as line intercept techniques were conducted at nine sites, looking at 14 common species of coral, representing four different growth forms. A total of 9,011 coral colonies were surveyed. 2,832 colonies (31.4%) were found to have at least one type of damage. It was expected that branching and digitate growth forms as well …
