RISTurbine Engine Performance Improvements—A Proactive Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Turbine engine concepts for the future are placing ever increasing demands on the design engineer. These future systems are seeking to increase performance while at the same time reduce costs. ...
Influence of the North Atlantic SST Variability on the Atmospheric Circulation during the Twentieth Century
Publisher: American Meteorological Society
Abstract: he ocean?atmosphere coupling in the North Atlantic is investigated during the twentieth century using maximum covariance analysis of sea surface temperature (SST) and 500-hPa geopotential height analyses and performing ...
The Influence of the AMOC Variability on the Atmosphere in CCSM3
Publisher: American Meteorological Society
Abstract: he influence of the Atlantic meridional overturning circulation (AMOC) variability on the atmospheric circulation is investigated in a control simulation of the NCAR Community Climate System Model, version 3 (CCSM3), where ...
The Influence of Autumnal Eurasian Snow Cover on Climate and Its Link with Arctic Sea Ice Cover
Publisher: American Meteorological Society
Abstract: AbstractThe relationship between Eurasian snow cover extent (SCE) and Northern Hemisphere atmospheric circulation is studied in reanalysis during 1979?2014 and in CMIP5 preindustrial control runs. In observations, dipolar ...
Untitled
Publisher: American Meteorological Society
Abstract: AbstractTwo large ensembles (LEs) of historical climate simulations are used to compare how various statistical methods estimate the sea surface temperature (SST) changes due to anthropogenic and other external forcing, ...
The Hadley and Walker Circulation Changes in Global Warming Conditions Described by Idealized Atmospheric Simulations
Publisher: American Meteorological Society
Abstract: Sea surface temperature (SST) changes constitute a major indicator and driver of climate changes induced by greenhouse gas increases. The objective of the present study is to investigate the role played by the detailed ...
Some Atmospheric Processes Governing the Large-Scale Tropical Circulation in Idealized Aquaplanet Simulations
Publisher: American Meteorological Society
Abstract: The large-scale tropical atmospheric circulation is analyzed in idealized aquaplanet simulations using an atmospheric general circulation model. Idealized sea surface temperatures (SSTs) are used as lower-boundary conditions ...
Wintertime Atmospheric Response to North Atlantic Ocean Circulation Variability in a Climate Model
Publisher: American Meteorological Society
Abstract: aximum covariance analysis of a preindustrial control simulation of the NCAR Community Climate System Model, version 4 (CCSM4), shows that a barotropic signal in winter broadly resembling a negative phase of the North ...
Climate Response to Atlantic Meridional Energy Transport Variations
Publisher: American Meteorological Society
Response Modification Approach for Safe Extension of Bridge Life
Publisher: American Society of Civil Engineers
Abstract: A large portion of highway bridges in the United States are reaching or have reached their intended design lives. To avoid replacing a large number of bridges simultaneously, methodologies to safely extend their lives are ...
