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 …

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 …

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 …

The interacting hydrologic responses to changing climate, watershed physical characteristics, river regulation, and land development in the northeastern United States
… and regime shifts 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 …

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
The principal patterns of variability of the extratropical Northern Hemisphere (NH) wintertime circulation are examined. The two-dimensional phase space defined by the two leading PCs of the monthly-mean sea-level pressure (SLP) field poleward of 20°N is used as a basis for surveying the structure …

Arctic synoptic activity associated with sea ice variability using self-organizing maps
… maps (SOMs) to categorize observed weather patterns over the 1979-2010 period. The European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-interim, or ERAI) provides the daily sea level pressures from which the SOMs are computed. Time series of frequencies and durations …

Southern African climate anomalies, summer rainfall and the Angola low
… anomaly relationships is carried out. Teleconnection patterns and coherent structure of interannual variability are revealed. Atmospheric mean meteorological features over Southern Africa and adjacent oceans have direct impact on summer rainfall. Thus determination of mean features …

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 …

Untersuchungen zur dynamischen Kopplung der Troposphäre und der Stratosphäre
Im Rahmen dieser Arbeit wurde ein besseres Verständnis der Kopplung der Troposphäre und der Stratosphäre in den mittleren und polaren Breiten der Nordhemisphäre (NH) auf Monatszeitskalen erzielt, die auf die Ausbreitung von quasi-stationären Wellen zurückzuführen ist. Der Schwerpunkt lag dabei auf …

Global Food Security Under Climate-Water-Energy Nexus
… of technology enhancement and major climatic patterns that impact crop yields, quantify and predict their impacts and find the trade strategies to minimize current and potential food shortages. Annually crop yields of the global countries are impacted by climatic variables deferentially in …
