RISSome Investigations Into Transonic Axial-Flow Compressors With High Stage Load Coefficients and Low Degrees of Reaction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A design for a transonic axial-flow compressor is described, in which a rotor wheel with a low degree of reaction operates in subsonic flow and the stator operates in supersonic flow. A ...
The Roles of Mean Meridional Motions and Large-Scale Eddies in Zonally Averaged Circulations
Publisher: American Meteorological Society
Abstract: A hierarchy of zonally averaged atmospheric models is used to study the role of mean meridional motions and large-scale eddies in determining the zonal climate. Five models are developed: a radiative-convective equilibrium ...
An Analysis of the Biases in Traditional Cyclone Frequency Maps
Publisher: American Meteorological Society
Abstract: The traditional method of estimating cyclone frequency by counting the number of storms passing through latitude-longitude grid cells is known to be biased because it effectively overweights the lower latitudes. Here we ...
A Vertical Finite-Difference Scheme for Hydrostatic and Nonhydrostatic Equations
Publisher: American Meteorological Society
Abstract: Vertical finite-differences schemes that preserve the important integral properties of the continuum equations are derived for the basic hydrodynamic and thermodynamic equations governing the atmosphere. The vertical ...
Nuclei in Snow and Ice Crystals on the Greenland Ice Cap under Natural and Artificially Stimulated Conditions
Publisher: American Meteorological Society
Abstract: Natural snow crystals and artificially stimulated snow and ice crystals were collected on a mesh prepared for electron microscopy at Site 2, a research facility on the ice cap about 320 km cast of Thule, Greenland. The ...
An Analysis of Cloud Liquid Water Feedback and Global Climate Sensitivity in a General Circulation Model
Publisher: American Meteorological Society
Abstract: A set of general circulation model simulations is analyzed to determine how cloud distribution and cloud radiative properties might change as climate warms and to isolate and quantify the various feedback effects of clouds ...
Simplified Moment Redistribution of Hybrid HPS 485W Bridge Girders in Negative Bending
Publisher: American Society of Civil Engineers
Abstract: Simplified moment redistribution procedures based on shakedown have recently been approved by AASHTO LRFD Bridge Design Specifications (AASHTO 2004). These procedures are currently only applicable for homogeneous girders, ...
Flexural Capacity of Compact Composite I-Girders in Positive Bending
Publisher: American Society of Civil Engineers
Abstract: Current American Association of State Highway and Transportation Officials (AASHTO) bridge specifications for compact composite steel girders in positive bending with adjacent compact pier sections limit the allowable ...
Improved Serviceability Criteria for Steel Girder Bridges
Publisher: American Society of Civil Engineers
Abstract: Current AASHTO LRFD Bridge Design Specifications Service I deflection limits are in place with the purpose to prevent deformation-induced structural damage and psychological user discomfort from excess bridge vibration. ...
Climate Forcings and Climate Sensitivities Diagnosed from Coupled Climate Model Integrations
Publisher: American Meteorological Society
Abstract: A simple technique is proposed for calculating global mean climate forcing from transient integrations of coupled atmosphere?ocean general circulation models (AOGCMs). This ?climate forcing? differs from the conventionally ...
