RISTurbulence-Scale Condensation Parameterization
Publisher: American Meteorological Society
Abstract: When a turbulence closure model is used for cloud simulations, the effect of turbulence-scale saturation must be taken into account in determining the turbulent buoyancy flux. Sommeria and Deardorff derived statistical ...
A Green's Function for the Domain Bounded by Nonconcentric Spheres
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The main result is the analytical derivation of Green's function for the domain bounded by nonconcentric spheres in terms of bispherical coordinates. Both surfaces, inner and outer boundaries, are specified by the Dirichlet ...
Interpretation of Extended Empirical Orthogonal Function (EEOF) Analysis
Publisher: American Meteorological Society
Abstract: Application of an empirical orthogonal function (EOF) analysis to a data matrix that contains two or more variable fields has been referred to as extended EOF (EEOF) analysis. Coherence between individual features contained ...
A Technique for Analyzing Optimal Relationships among Multiple Sets of Data Fields. Part H: A Reliability Case Study
Publisher: American Meteorological Society
Abstract: In Part I a multiple-set canonical correlation analysis (MCCA) was proposed to generalize the conventional two-set canonical correlation analysis. The MCCA seeks the optimal correlation among more than two data fields ...
Effects of Cloud Seeding, Latent Heat of Fusion, and Condensate Loading on Cloud Dynamics and Precipitation Evolution: A Numerical Study
Publisher: American Meteorological Society
Abstract: This study attempts to isolate the dynamic and microphysical effects of seeding. A two-dimensional, time-dependent cloud model has been used to simulate silver iodide (AgI) seeding of convective clouds. Two major dynamic ...
True and Spurious Eigensolutions of an Elliptical Membrane by Using the Nondimensional Dynamic Influence Function Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we employ the nondimensional dynamic influence function (NDIF) method to solve the free vibration problem of an elliptical membrane. It is found that the spurious eigensolutions appear in the Dirichlet problem ...
A Technique for Analyzing Optimal Relationships among Multiple Sets of Data Fields. Part 1: The Method
Publisher: American Meteorological Society
Abstract: A multiple-set canonical correlation analysis (MCCA), which can be used to study atmospheric motions by analyzing the relationships among more than two sets of data fields, is proposed. By using the product or squared ...
Steady State Heat Conduction in Exchanger Tubes by Using the Meshfree Boundary Integral Equation Method: Conduction Shape Factor and Degenerate Scale
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Regarding the steady-state heat conduction problem in exchanger tubes, the meshfree boundary integral equation method is employed to determine the conduction shape factor in this paper. Different from the conventional ...
Thermal Stress Analysis of Free-Free Trusses under Temperature Change Using a Self-Regularized Approach
Publisher: American Society of Civil Engineers
Abstract: AbstractIn this study, a self-regularized approach was employed to determine the thermal stress
in a free-free truss, which results in a singular stiffness matrix. Physically, the
stiffness and flexibility matrices of ...
A Simple Statistical-Synoptic Track Prediction Technique for Western North Pacific Tropical Cyclones
Publisher: American Meteorological Society
Abstract: A simple statistical-synoptic technique for tropical cyclone (TC) track forecasting to 72 h in the western North Pacific is derived. This technique applies to the standard (S) pattern/dominant ridge region (S/DR) and ...
