On the Relationship between the Stratospheric Quasi-biennial Oscillation and the Tropospheric Southern Oscillation
Publisher: American Meteorological Society
Abstract: Two quasi-periodic oscillations in the tropical atmosphere with similar oscillation period?the stratospheric quasi-biennial and the Southern oscillations?and the relationship between these two oscillations are examined ...
The Joint Modes of the Coupled Atmosphere-Ocean System Observed from 1967 to 1986
Publisher: American Meteorological Society
Abstract: Two aspects of the principal oscillation pattern (POP) analysis are used to study the large-scale modes of the coupled atmosphere?ocean system. First, P0Ps can be considered as the normal modes of the system; one way of ...
Research on the Static and Dynamic Characteristics of Porous Air Bearings Considering Annular Groove Air Supply
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The article examines the dynamic characteristics of porous air bearings in the critical pneumatic hammer state (the transition state from the steady state to the pneumatic hammer state). The dynamic characteristics mainly ...
Transport of Atmospheric Aerosol by Gap Winds in the Columbia River Gorge
Publisher: American Meteorological Society
Abstract: Typical diurnal wind patterns and their relationship to transport of atmospheric aerosol in the Columbia River gorge of Oregon and Washington are addressed in this paper. The measurement program included measurements of ...
Predicting the State of the Southern Oscillation Using Principal Oscillation Pattern Analysis
Publisher: American Meteorological Society
Abstract: Principal oscillation pattern (POP) analysis is a diagnostic technique for deriving the space-time characteristics of a dataset objectively. A multiyear dataset of monthly mean sea level pressure (SLP) in the area 15°S to ...
Investigation on Flow Characteristics and Its Effect on Heat Transfer Enhancement in a Wide Channel With Staggered Diamond-S Pin Fins
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flow statistic in the mid-plane of a rectangular channel with diamond-s pin fins was obtained by means of particle imaging velocimetry at Re = 10,000. Large-scale and small-scale fluctuations were separated using proper ...
Comparative Study of the Effect of Basalt Fiber on Dynamic Damage Characteristics of Ceramics Cement–Based Porous Material
Publisher: American Society of Civil Engineers
Abstract: Cementitious materials, ceramic aggregates, and fiber are used as basic materials; ceramics cement–based porous material (CCPM) and basalt fiber-reinforced ceramics cement–based porous material (BFRCCPM) are prepared on ...
The Performance of Four Spectral GCMs in the Southern Hemisphere: The January and July Climatology and the Semiannual Wave
Publisher: American Meteorological Society
Abstract: Monthly mean sea level pressure (SLP) data from four low-resolution spectral GCMs?ECMWF T21, CCC, NCAR CCM and GFDL R15?are compared with observations for the Southern Hemisphere. Characteristics of the observed Southern ...
Micro-Asperity Contact Area Considering Strain Hardening for Metallic Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel micro-asperity contact area model, which considers influences of strain hardening, is proposed to describe contact area between a deformable sphere and a rigid flat for metallic materials. First, a generalized ...
Study on the Friction and Wear Performance of Graphene/Porous Bronze Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The porous surface of air bearings may suffer from surface scratching and wear issues during the start–stop processes or under extreme working conditions. To improve the lubrication performance and service life of the ...
