A Turbulence Closure for the Convective Boundary Layer Based on a Two-Scale Mass-Flux Approach
(American Meteorological Society, 2002)The closure problem for the convective turbulence of the shear-free and low to moderate wind atmospheric boundary layer is considered. Non-Gaussian parameterizations are developed for fourth-order moments based on a two-scale ... -
Space–Time Characteristics of Light Transmitted through Dense Clouds: A Green's Function Analysis
(American Meteorological Society, 2002)Here, previous work using photon diffusion theory to describe radiative transfer through dense plane-parallel clouds at nonabsorbing wavelengths is extended. The focus is on the scaling of space- and time-domain moments ... -
Perturbation Growth and Structure in Uncertain Flows. Part I
(American Meteorological Society, 2002)Perturbation growth in uncertain systems is examined and related to previous work in which linear stability concepts were generalized from a perspective based on the nonnormality of the underlying linear operator. In this ... -
Teleconnection Mechanisms for Tropical Pacific Descent Anomalies during El Niño
(American Meteorological Society, 2002)Teleconnection mechanisms in relative descent zones are examined using the quasi-equilibrium tropical circulation model (QTCM). The regions of anomalous descent neighboring the warm sea surface temperature (SST) anomalies ... -
Rossby Waves in Zonal Barotropic Flows with Pseudocritical Levels
(American Meteorological Society, 2002)A pseudocritical level is defined as a region where the wave phase speed c equals the zonal basic flow velocity U and, additionally, the background potential vorticity gradient vanishes. In this study Rossby wave propagation ... -
Comments on “Critical Test of the Validity of Monin–Obukhov Similarity during Convective Conditions”

Diurnal Cycle of Supercritical Along-Coast Flows
(American Meteorological Society, 2002)In this study, a three-dimensional hydrostatic mesoscale model is used to address the transient behavior of supercritical along-coast flow. A control experiment and several sensitivity tests are performed in order to ... -
How Important Is the Spectral Ripening Effect in Stratiform Boundary Layer Clouds? Studies Using Simple Trajectory Analysis
(American Meteorological Society, 2002)Any population of cloud droplets forming on polydisperse condensation nuclei is thermodynamically unstable. There is no value of the supersaturation for which the growth rate of all the droplets is zero, so that if some ... -

A Mixed-Layer Model of the Diurnal Dryline
(American Meteorological Society, 2002)This study examines the diurnal behavior of the dryline system using a mixed-layer model to represent the cool moist air capped by an inversion to the east of the line. This inversion is referred to as the dry front, and ... -
Observations of Flow and Turbulence in the Nocturnal Boundary Layer over a Slope
(American Meteorological Society, 2002)Measurements were conducted on an eastern slope of the Salt Lake Basin (SLB) as a part of the Vertical Transport and Mixing Experiment (VTMX) conducted in October 2000. Of interest was the nocturnal boundary layer on a ... -
Similarity of Deep Continental Cumulus Convection as Revealed by a Three-Dimensional Cloud-Resolving Model
(American Meteorological Society, 2002)A three-dimensional cloud-resolving simulation of midlatitude continental convection during the Atmospheric Radiation Measurement (ARM) program summer 1997 intensive observation period (IOP) is used to study the similarity ... -
Short-Term Dynamics of Model Errors
(American Meteorological Society, 2002)The natural instability of the atmosphere is at the origin of the rapid amplification of errors coming from the uncertainty on the initial conditions and from the imperfect representation (the model) of the atmospheric ... -
Convective Momentum Transport Observed during the TOGA COARE IOP. Part II: Case Studies
(American Meteorological Society, 2002)Convective momentum transport (CMT) associated with the Madden?Julian oscillation (MJO), tropical waves, squall and nonsquall mesoscale convective systems (MCSs), and the diurnal cycle is studied by examining the momentum ... -
Intermittent Turbulence and Oscillations in the Stable Boundary Layer over Land. Part II: A System Dynamics Approach
(American Meteorological Society, 2002)In the stable boundary layer it is often observed that turbulence is not continuous in space and time. This discontinuous, intermittent turbulence causes alterations from the mean evolution of the stratified atmospheric ... -
Large Eddy Simulation of an Inhomogeneous Atmospheric Boundary Layer under Neutral Conditions
(American Meteorological Society, 2002)Flow structures in an inhomogeneous neutrally stratified atmospheric boundary layer flow, obtained from large eddy simulation, are analyzed and compared with homogeneous case counterparts. The inhomogeneity is imposed in ... -
Mesoscale Variability of Tropical Precipitation: Validation of Satellite Estimates of Wave Forcing Using TOGA COARE Radar Data
(American Meteorological Society, 2002)Satellite-derived brightness temperature has been used to estimate tropical precipitation. Ricciardulli and Garcia applied it to quantify forcing of atmospheric waves that are excited by tropical cumulus convection and ... -
Recovery Processes and Factors Limiting Cloud-Top Height following the Arrival of a Dry Intrusion Observed during TOGA COARE
(American Meteorological Society, 2002)This study investigates the recovery of the tropical atmosphere to moist conditions following the arrival of a dry intrusion observed during the Tropical Ocean and Global Atmosphere Program Coupled Ocean?Atmosphere Response ... -
A New Parameterization of Single Scattering Solar Radiative Properties for Tropical Anvils Using Observed Ice Crystal Size and Shape Distributions
(American Meteorological Society, 2002)Parameterizations of single scattering properties currently used in cloud resolving and general circulation models are somewhat limited in that they typically assume the presence of single particle habits, do not adequately ...
