Drinking Water Infrastructure Assessment with Teleconnection Signals, Satellite Data Fusion and Mining
… impact of long-term hydrological droughts, teleconnection signals were included on a seasonal basis in the Upper Colorado River basin which provides 97% of the inflow into Lake Mead. Identification of teleconnection patterns at a local scale is challenging, largely due to the coexistence of …

Analysis of Virginia Barrier Island Shoreline Movement and Correlations to Sea Level, Wave Height Changes, and Teleconnection Patterns
… of sea level rise, changes in wave height, and teleconnection pattern (AO, NAO, and MEI) correlations to shoreline location changes to the islands and inlet location and width changes. Locations of island shorelines were determined from satellite and aircraft images using ArcGIS software and the …

Preparation for CWRF downscaling climate prediction over Pakistan: development of iCWPS surface processing and analysis of regional precipitation teleconnection
… and [2] Analysis of Pakistan precipitation teleconnection with planetary circulation patterns that facilitate the optimal domain position for the CWRF to realistically integrate large-scale forcings. Current study is aimed at the optimal domain definition with dynamical downscaling as a …

El Niño Southern Oscillation teleconnections and their effects on the Amundsen Sea region
… and socio-economically. One such climatological teleconnection is manifested in the Amundsen Sea region (ASR). The Amundsen sea low (ASL) is the dominant low pressure system located around the ASR and is important to the climate of Western Antarctica. Therefore, it is important to understand the …

Assessing the representation of teleconnective drivers of rainfall over Eastern Africa in global and regional climate models and projected future changes
… and a subject to significant control from teleconnections. An extended diagnosis of the capacity of climate models to represent remote controls of regional climate (teleconnections) is vital for assessing model-based predictions of climate variability, understanding uncertainty in climate …

Modeling spatial covariance functions
… waves propagation. This phenomenon is called teleconnection and often considered to be responsible for extreme weather events occurring simultaneously around the world. In the second part of the dissertation, a nonstationary spatial covariance model for long-distance dependence is proposed. …

Non-Parametric Spatial Models
… there are times it fails to hold such as in the teleconnection in climatology.</p> <p>The dissertation can be divided into two parts. In the first part, we propose a non-parametric low-rank model, which is a non- parametric extension of the parametric low-rank models that have been studied by …

Arctic synoptic activity associated with sea ice variability using self-organizing maps
… pan-Arctic sea ice extent. When compared to teleconnection indices commonly associated with sea ice variability, the Arctic Oscillation (AO), North Atlantic Oscillation (NAO), and Arctic Dipole (AD), some SOM patterns correlate more strongly with sea ice metrics. For example, Beaufort High …

Evaluating the impact of oceanic/atmospheric teleconnections on historical wildfires in West Virginia (1939--2006)
… ways. This study quantitatively examined climate teleconnection patterns and in turn analyzed the influence of climate on wildfire activity within West Virginia from 1939--2006. Identifying the linkages between oscillations and climate variability has the potential to greatly improve seasonal …

Addressing Water Resource Issues In Barbados Through An Isotopic and Atmospheric Characterization of Precipitation Variability
… based upon storm type, frequency, intensity, and teleconnection activity in the tropical karst areas. At Harrison’s Cave, Barbados, a Hobo Onset event data logger was attached to a tipping bucket rain gauge to count the tips and record the total rainfall every 10 minutes. In the cave a Hobo data …

MULTI-FACTOR ANALYSIS OF HYDRO-MORPHOLOGICAL DYNAMICS IN THE PAJARO RIVER LAGOON
… in summer, maximizes migration rates.Climate teleconnection analysis revealed weak correlations between watershed precipitation and ENSO (r = 0.11) and PDO (r = -0.04). The study demonstrates that local hydrological conditions are more influential than large-scale climate oscillations in …

Assessing impacts of climate change on the hydrology of the Nile River
… provide a physically-based explanation of this teleconnection. Then, we build on this teleconnection and future predications regarding the frequency of El Niño and La Nina events to project enhancement in future variability of the flow in the Nile river. Second, an improved version of the MIT …

Winter climate response to continental snow anomalies
… winter climate response occurs via anatmospheric teleconnection pathway involving established stationary wave - mean flow interaction processes throughout the troposphere and stratosphere. The pathway is enabled by the specific and unique geographic and orographic conditions that exist in Siberia, …

The interacting hydrologic responses to changing climate, watershed physical characteristics, river regulation, and land development in the northeastern United States
… of large-scale circulation patterns and their teleconnection patterns were evaluated using long-term precipitation and discharge records in sub-basins with no development, and extensive development and riverine impoundments of the Merrimack River watershed. The Merrimack (New …

A Reconstruction of Post-Glacial Hydroclimatic Change and Mass Accumulation Rates from a Small Watershed of the Lower North American Great Lakes Region
… the negative phase of the Pacific-North American teleconnection and/or the positive phase of the Atlantic Multidecadal Oscillation. Reconstructions of organic, carbonate, and siliciclastic mass accumulation rates show an overall insensitivity to climate change. Primary productivity was steady …

The role of historical land-cover changes as a mechanism for global and regional climate change
… to propagate to the extratropics in well-defined teleconnection patterns, and reduced low-level easterlies over most of the topical Pacific basin under current vegetation. This implies an interaction mechanism between tropical deforestation and ENSO. The model simulations of climate change due to …

Patterns of climate variability of the Northern Hemisphere wintertime circulation
… are suggestions of multiple circulation regimes; teleconnection patterns for the subsets of the climatology are also discernibly different; cold temperature anomalies associated with low polarities of both PCs are observed more frequently than expected on the basis of linear correlation analysis. …
