RISOn the Verification and Comparison of Extreme Rainfall Indices from Climate Models
Publisher: American Meteorological Society
Abstract: The interpretation of model precipitation output (e.g., as a gridpoint estimate versus as an areal mean) has a large impact on the evaluation and comparison of simulated daily extreme rainfall indices from climate models. ...
Time-Mean Response over the Tropical Pacific to Increased C02 in a Coupled Ocean-Atmosphere Model
Publisher: American Meteorological Society
Abstract: The time-mean response over the tropical Pacific region to a quadrupling Of CO2 is investigated using a global coupled ocean-atmosphere general circulation model. Tropical Pacific sea surface temperatures (SSTs) rise by ...
Model Assessment of Decadal Variability and Trends in the Tropical Pacific Ocean
Publisher: American Meteorological Society
Abstract: In this report, global coupled ocean?atmosphere models are used to explore possible mechanisms for observed decadal variability and trends in Pacific Ocean SSTs over the past century. The leading mode of internally generated ...
Sea Level Pressure Trends: Model-Based Assessment of Detection, Attribution, and Consistency with CMIP5 Historical Simulations
Publisher: American Meteorological Society
Model Assessment of Observed Precipitation Trends over Land Regions: Detectable Human Influences and Possible Low Bias in Model Trends
Publisher: American Meteorological Society
Abstract: AbstractPrecipitation trends for 1901?2010, 1951?2010, and 1981?2010 over relatively well-observed global land regions are assessed for detectable anthropogenic influences and for consistency with historical simulations ...
On Estimates of Historical North Atlantic Tropical Cyclone Activity
Publisher: American Meteorological Society
Abstract: In this study, an estimate of the expected number of Atlantic tropical cyclones (TCs) that were missed by the observing system in the presatellite era (between 1878 and 1965) is developed. The significance of trends in ...
Material Orientation Artifact Studies in Magnetic Resonance Imaging
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the increased interest of MRI guided interventional procedures in modern medical treatments, image distortion and artifact formation based on material selection and orientation within the MRI ...
Impact of CO2-Induced Warming on Simulated Hurricane Intensity and Precipitation: Sensitivity to the Choice of Climate Model and Convective Parameterization
Publisher: American Meteorological Society
Abstract: Previous studies have found that idealized hurricanes, simulated under warmer, high-CO2 conditions, are more intense and have higher precipitation rates than under present-day conditions. The present study explores the ...

Publisher: American Meteorological Society
Abstract: A response is made to the comments of Michaels et al. concerning a recent study by the authors. Even after considering Michaels et al.?s comments, the authors stand behind the conclusions of the original study. In contrast ...
30–60 Day Atmospheric Oscillations: Composite Life Cycles of Convection and Circulation Anomalies
Publisher: American Meteorological Society
Abstract: Life cycles of the 30?60 day atmospheric oscillation were examined by compositing 30?60 day filtered NMC global wind analyses (250 mb and 850 mb) and outgoing longwave radiation (OLR) for the years 1979?84. Separate composite ...
