RISAn Empirical Benchmark for Decadal Forecasts of Global Surface Temperature Anomalies
Publisher: American Meteorological Society
Abstract: he suitability of a linear inverse model (LIM) as a benchmark for decadal surface temperature forecast skill is demonstrated. Constructed from the observed simultaneous and 1-yr lag covariability statistics of annually ...
Statistical Investigation of Anomalies in the Winter Temperature Record of Boston, Massachusetts
Publisher: American Meteorological Society
Abstract: Normal maximum and minimum temperatures are computed for each date of the winter season from the 92-year Boston temperature record. The trend is removed from the normal and individual yearly values and standard deviations ...
Interannual to Decadal Predictability of Tropical and North Pacific Sea Surface Temperatures
Publisher: American Meteorological Society
Abstract: A multivariate empirical model is used to show that predictability of the dominant patterns of tropical and North Pacific oceanic variability, El Niño?Southern Oscillation (ENSO), and the Pacific decadal oscillation (PDO), ...
Geometric Instabilities in Isotropic Plastic Solids Under Increasing Uniaxial Compression
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This analysis seeks three-dimensional instabilities of uniaxial compressive flow in isotropic, strain-hardening, rigid-plastic materials of the Mises and maximum shear stress types. No instabilities ...
Fatigue-Life Prediction Methodology Using a Crack-Closure Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reviews the capabilities of a plasticity-induced crack-closure model and life-prediction code, FASTRAN, to predict fatigue lives of metallic materials using small-crack theory. Crack-tip ...
The Impact of Rapid Wind Variability upon Air–Sea Thermal Coupling
Publisher: American Meteorological Society
Abstract: The basic effect of extratropical atmosphere?ocean thermal coupling is to enhance the variance of both anomalous sea surface temperatures (SSTs) and air temperatures (AIRT) due to a decreased energy flux between the ...
New Liapunov Function for Nonlinear Time-Varying Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new method of generating Liapunov functions is described that is useful for time-varying nonlinear differential equations. Constant coefficient quadratic forms are often used as Liapunov functions ...
Stability and Performance Limits of Interaction Controllers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Theoretical performance limits of controlled systems which interact with dynamic environments are analyzed from consideration of simple, single-axis mass-spring-damper systems. A measure of interaction ...
Rossby Wave Propagation and the Rapid Development of Upper-Level Anomalous Anticyclones during the 1988 U.S. Drought
Publisher: American Meteorological Society
Abstract: The upper-tropospheric circulation is investigated for the three months of April, May, and June 1988 during which the Great Plains region of the United States experienced one of its most severe droughts in history. It is ...
Elongation and Contraction of the Western Boundary Current Extension in a Shallow-Water Model: A Bifurcation Analysis
Publisher: American Meteorological Society
Abstract: The double-gyre circulation, formulated in terms of the quasigeostrophic equations, has a symmetry about the basin midlatitude (y ? ?y, ? ? ??), which is absent in a formulation based on the shallow-water equations. As a ...
