Comments on “The Barotropic Normal Modes in Certain Shear Flows and the Traveling Waves in the Atmosphere”
(American Meteorological Society, 2004) -
Observed Nondiffusive Dynamics in Large-Scale Atmospheric Flow
(American Meteorological Society, 2004)The dynamics of large-scale atmospheric flow is characterized by both noisy, diffusive behavior, stemming mainly from small-scale, high-frequency atmospheric processes and by more structured, nondiffusive aspects, coming ... -
CORRIGENDUM

The Atmospheric Energy Budget and Large-Scale Precipitation Efficiency of Convective Systems during TOGA COARE, GATE, SCSMEX, and ARM: Cloud-Resolving Model Simulations
(American Meteorological Society, 2004)A two-dimensional version of the Goddard Cumulus Ensemble (GCE) model is used to simulate convective systems that developed in various geographic locations (east Atlantic, west Pacific, South China Sea, and Great Plains ... -
Mathematical–Physical Framework for Retrieval of Rain DSD Properties from Dual-Frequency Ku–Ka-Band Satellite Radar
(American Meteorological Society, 2004)In developing the upcoming Global Precipitation Measurement (GPM) mission, a dual-frequency Ku?Ka-band radar system will be used to measure rainfall in such a fashion that the reflectivity ratio intrinsic to the measurement ... -
Eliassen–Palm Flux Diagnosis Based on Isentropic Representation
(American Meteorological Society, 2004)This paper demonstrates an isentropic representation of the Eliassen?Palm flux (EP flux) as a tool for diagnosis of the atmospheric zonal mean states. This is a full extension of the transformed Eulerian mean (TEM) to ... -
Effect of Surface Waves on Air–Sea Momentum Exchange. Part II: Behavior of Drag Coefficient under Tropical Cyclones
(American Meteorological Society, 2004)Present parameterizations of air?sea momentum flux at high wind speed, including hurricane wind forcing, are based on extrapolation from field measurements in much weaker wind regimes. They predict monotonic increase of ... -
Sensitivities of Cumulus-Ensemble Rainfall in a Cloud-Resolving Model with Parameterized Large-Scale Dynamics
(American Meteorological Society, 2004)The problem of closure in cumulus parameterization requires an understanding of the sensitivities of convective cloud systems to their large-scale setting. As a step toward such an understanding, this study probes some ... -
Barotropic Beta-Plane Turbulence in a Regime with Strong Zonal Jets Revisited
(American Meteorological Society, 2004)The problem of quantification of barotropic beta-plane turbulence driven by small-scale stochastic forcing into regimes dominated by quasi-periodic zonal jets is revisited. It is shown that the large-scale relative vorticity ... -
Field Experimental Study of Dynamic Smagorinsky Models in the Atmospheric Surface Layer
(American Meteorological Society, 2004)An analysis of dynamic Smagorinsky models is performed based on the Horizontal Array Turbulence Study (HATS) dataset. In the experiment, two vertically separated horizontal arrays of 14 three-dimensional sonic anemometers ... -
Effect of Surface Waves on Air–Sea Momentum Exchange. Part I: Effect of Mature and Growing Seas
(American Meteorological Society, 2004)The effect of surface waves on air?sea momentum exchange over mature and growing seas is investigated by combining ocean wave models and a wave boundary layer model. The combined model estimates the wind stress by explicitly ... -
Gravity Wave Breaking over the Central Alps: Role of Complex Terrain
(American Meteorological Society, 2004)The characteristics of gravity waves excited by the complex terrain of the central Alps during the intensive observational period (IOP) 8 of the Mesoscale Alpine Programme (MAP) is studied through the analysis of aircraft ... -
Effects of Convectively Generated Gravity Waves and Rotation on the Organization of Convection
(American Meteorological Society, 2004)The effects of latent heating, gravity waves, and planetary rotation on numerically simulated convective cloud systems are investigated. First, the nonlinear response of an initially motionless, uniformly stratified, dry ... -
Strategies for Model Reduction: Comparing Different Optimal Bases
(American Meteorological Society, 2004)Several different ways of constructing optimal bases for efficient dynamical modeling are compared: empirical orthogonal functions (EOFs), optimal persistence patterns (OPPs), and principal interaction patterns (PIPs). ... -
A Model for Convectively Coupled Tropical Waves: Nonlinearity, Rotation, and Comparison with Observations
(American Meteorological Society, 2004)Recent observational analysis of both individual realizations and statistical ensembles identifies moist convectively coupled Kelvin waves in the Tropics with supercluster envelopes of convection. This observational analysis ... -
Preferred Regime Transition Routes and Evidence for an Unstable Periodic Orbit in a Baroclinic Model
(American Meteorological Society, 2004)The phase space structure of the attractor of a baroclinic quasigeostrophic model is analyzed in terms of mean tendencies in dominant EOF space. The dominant EOFs as well as the probability density functions in the planes ... -
Light Scattering by Quasi-Spherical Ice Crystals
(American Meteorological Society, 2004)The shapes and single-scattering properties of small, irregular, quasi-spherical ice crystals, with equivalent radii between approximately 8 and 90 ?m and size parameters from about 90 to 1000, are studied using two-dimensional ... -
Nonlinear Dynamics and Chaos in the Sea and Land Breeze
(American Meteorological Society, 2004)In this work the evolution of the sea and land breeze is studied using a nonlinear model under calm synoptic conditions and diurnal periodic forcing of ground temperature. The breeze is examined as a function of the strength ... -
