RISAtmospheric Circulation Trends, 1950–2000: The Relative Roles of Sea Surface Temperature Forcing and Direct Atmospheric Radiative Forcing
Publisher: American Meteorological Society
Abstract: The relative roles of direct atmospheric radiative forcing (due to observed changes in well-mixed greenhouse gases, tropospheric and stratospheric ozone, sulfate and volcanic aerosols, and solar output) and observed sea ...
Simulation of the 1976/77 Climate Transition over the North Pacific: Sensitivity to Tropical Forcing
Publisher: American Meteorological Society
Abstract: This study examines the contribution of tropical sea surface temperature (SST) forcing to the 1976/77 climate transition of the winter atmospheric circulation over the North Pacific using a combined observational and ...
Tropical Atlantic Influence on European Heat Waves
Publisher: American Meteorological Society
Abstract: Diagnostics combining atmospheric reanalysis and station-based temperature data for 1950?2003 indicate that European heat waves can be associated with the occurrence of two specific summertime atmospheric circulation ...
Tropical Atmospheric Variability Forced by Oceanic Internal Variability
Publisher: American Meteorological Society
Abstract: Atmospheric general circulation model experiments are conducted to quantify the contribution of internal oceanic variability in the form of tropical instability waves (TIWs) to interannual wind and rainfall variability in ...
Large-Scale Experimental Study of Ring Shaped–Steel Plate Shear Walls
Publisher: American Society of Civil Engineers
Abstract: The ring shaped–steel plate shear wall (RS-SPSW) is a new lateral load resisting system that offers improved seismic energy dissipation and stiffness over conventional steel plate shear wall systems. Thicker web plates ...
Forced and Internal Components of Winter Air Temperature Trends over North America during the past 50 Years: Mechanisms and Implications
Publisher: American Meteorological Society
Abstract: his study elucidates the physical mechanisms underlying internal and forced components of winter surface air temperature (SAT) trends over North America during the past 50 years (1963?2012) using a combined observational ...
Pacific Interdecadal Climate Variability: Linkages between the Tropics and the North Pacific during Boreal Winter since 1900
Publisher: American Meteorological Society
Abstract: This study examines the tropical linkages to interdecadal climate fluctuations over the North Pacific during boreal winter through a comprehensive and physically based analysis of a wide variety of observational datasets ...
The Effects of North Atlantic SST and Sea Ice Anomalies on the Winter Circulation in CCM3. Part II: Direct and Indirect Components of the Response
Publisher: American Meteorological Society
Abstract: The wintertime atmospheric circulation responses to observed patterns of North Atlantic sea surface temperature and sea ice cover trends in recent decades are studied by means of experiments with an atmospheric general ...
Detection and Attribution of Twentieth-Century Northern and Southern African Rainfall Change
Publisher: American Meteorological Society
Abstract: The spatial patterns, time history, and seasonality of African rainfall trends since 1950 are found to be deducible from the atmosphere?s response to the known variations of global sea surface temperatures (SSTs). The ...
Tropical Pacific and Atlantic Climate Variability in CCSM3
Publisher: American Meteorological Society
Abstract: Simulations of the El Niño?Southern Oscillation (ENSO) phenomenon and tropical Atlantic climate variability in the newest version of the Community Climate System Model [version 3 (CCSM3)] are examined in comparison with ...
