RISLinear Stability of Free Planetary Waves in the Presence of Radiative–Photochemical Feedbacks
Publisher: American Meteorological Society
Abstract: A simple ?-plane model that couples radiative transfer, ozone advection, and ozone photochemistry with the quasi-geostrophic dynamical circulation is used to study the diabatic effects of Newtonian cooling and ozone?dynamics ...
The Global Atmospheric Response to Low-Frequency Tropical Forcing: Zonally Averaged Basic States
Publisher: American Meteorological Society
Abstract: The extratropical response to localized, low-frequency tropical forcing is examined using a linearized, non-divergent barotropic model on a sphere. Zonal-mean basic states characterized by solid-body rotation or critical ...
Effects of Low-Frequency Tropical Forcing on Intraseasonal Tropical–Extratropical Interactions
Publisher: American Meteorological Society
Abstract: A spherical nondivergent barotropic model, linearized about a 300-mb climatological January flow, is used to examine the extratropical response to low-frequency tropical forcing. A two-dimensional WKB analysis shows that ...
Estimates of Threshold Wind Speeds for Snow Transport Using Meteorological Data
Publisher: American Meteorological Society
Abstract: The threshold wind speed for snow transport is related to properties of the surface snowpack: snow particle bonding, cohesion, and kinetic friction. These properties are controlled by meteorological factors. A method is ...
Fatigue Life Analysis of Composite Pavement with Multiple Overlays
Publisher: American Society of Civil Engineers
Abstract: Two 3D finite element models are established to analyze the mechanical response of road construction and solve the problem in which the actual fatigue life of the overlay is significantly shorter than the designed value. ...
Dynamic Strength of Molecular Bond Clusters Under Displacement and Force Controlled Loading Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Existing experimental and theoretical studies on the adhesion of molecular bond clusters are usually based on either displacementor forcecontrolled loading conditions. Very few studies have addressed whether or not and how ...
Evaluation of the NOHRSC Snow Model (NSM) in a One-Dimensional Mode
Publisher: American Meteorological Society
Abstract: The National Operational Hydrologic Remote Sensing Center (NOHRSC) Snow Model (NSM) is an energy- and mass-balance model used by the National Oceanic and Atmospheric Administration?s National Weather Service for ...
Modified Outlet Boundary Condition Schemes for Large Density Ratio Lattice Boltzmann Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Outlet boundary conditions (OBCs) and their numerical descriptions are critical to computational fluid dynamics (CFD) since they have significant influence on the numerical accuracy and stability. They present significant ...

Cascade Invulnerability of an Urban Agglomeration Highway–Railway Composite Network Considering Node Differences
Publisher: American Society of Civil Engineers
Abstract: Urban agglomeration transport network is affected by risks such as internal failure, natural disasters or deliberate attacks, which can easily lead to functional fragmentation and make it difficult to meet the needs of ...
