Large-Amplitude Mountain Wave Breaking over Greenland
(American Meteorological Society, 2005)A large-amplitude mountain wave generated by strong southwesterly flow over southern Greenland was observed during the Fronts and Atlantic Storm-Track Experiment (FASTEX) on 29 January 1997 by the NOAA G-IV research aircraft. ... -
The Coupled Stratosphere–Troposphere Response to Impulsive Forcing from the Troposphere
(American Meteorological Society, 2005)A simple atmospheric general circulation model (GCM) is used to investigate the transient response of the stratosphere?troposphere system to externally imposed pulses of lower-tropospheric planetary wave activity. The ... -
Downward Wave Propagation on the Polar Vortex
(American Meteorological Society, 2005)This paper considers the propagation of waves on the edge of a stratospheric polar vortex, represented by a three-dimensional patch of uniform potential vorticity in a compressible quasigeostrophic system. Waves are ... -
Diagnosis of Subtropical Humidity Dynamics Using Tracers of Last Saturation
(American Meteorological Society, 2005)A technique for diagnosing the mechanisms that control the humidity in a general circulation model (GCM) or observationally derived meteorological analysis dataset is presented. The technique involves defining a large ... -
Drizzle in Stratiform Boundary Layer Clouds. Part II: Microphysical Aspects
(American Meteorological Society, 2005)This is the second of two observational papers examining drizzle in stratiform boundary layer clouds. Part I details the vertical and horizontal structure of cloud and drizzle parameters, including some bulk microphysical ... -
The Influence of Uniform Flow on Tropical Cyclone Intensity Change
(American Meteorological Society, 2005)The influence of a uniform flow on the structural changes of a tropical cyclone (TC) is investigated using the fifth-generation Pennsylvania State University?National Center for Atmospheric Research Mesoscale Model (MM5). ... -
Analytic Green’s Function for Radiative Transfer in Plane-Parallel Atmospheres
(American Meteorological Society, 2005)Green?s function is a widely used approach for boundary value problems. In problems related to radiative transfer, Green?s function has been found to be useful in land, ocean, and atmosphere remote sensing. It is also a ... -
Drizzle in Stratiform Boundary Layer Clouds. Part I: Vertical and Horizontal Structure
(American Meteorological Society, 2005)Detailed observations of stratiform boundary layer clouds on 12 days are examined with specific reference to drizzle formation processes. The clouds differ considerably in mean thickness, liquid water path (LWP), and droplet ... -
Destabilization of the Symmetric Vortex and Formation of the Elliptical Eye of Typhoon Herb
(American Meteorological Society, 2005)An elliptical eye was observed in Typhoon Herb during its passage around the Sakishima Islands located in the southwest of the Okinawa Islands in Japan on 30?31 July 1996. Later analysis showed that this elliptical eye had ... -
Predictability and Information Theory. Part II: Imperfect Forecasts
(American Meteorological Society, 2005)This paper presents a framework for quantifying predictability based on the behavior of imperfect forecasts. The critical quantity in this framework is not the forecast distribution, as used in many other predictability ... -
The Dynamics of Orographic Wake Formation in Flows with Upstream Blocking
(American Meteorological Society, 2005)The development of orographic wakes and vortices is revisited from the dynamical perspective of a three-dimensional (3D) vorticity-vector potential formulation. Particular emphasis is given to the role of upstream blocking ... -

Zonal and Vertical Structure of the Madden–Julian Oscillation
(American Meteorological Society, 2005)A statistical study of the three-dimensional structure of the Madden?Julian oscillation (MJO) is carried out by projecting dynamical fields from reanalysis and radiosonde data onto space?time filtered outgoing longwave ... -
Trend Analysis for Atmospheric Hydrocarbon Partitioning Using Continuous Thermodynamics
(American Meteorological Society, 2005)The partitioning of atmospheric hydrocarbons into vapor and condensed phases when the species count is large is considered using the formalism of continuous thermodynamics. The vapor saturation pressures and condensate ... -
Nonlinear Atmospheric Adjustment to Thermal Forcing
(American Meteorological Society, 2005)A nonlinear, numerical model of a compressible atmosphere is used to simulate the hydrostatic and geostrophic adjustment to a localized prescribed heating applied over five minutes with a size characteristic of an isolated, ... -

Eulerian Available Energetics in Moist Atmospheres
(American Meteorological Society, 2005)A new derivation of local available energy for a compressible, multicomponent fluid that allows for frictional, diabatic, and chemical (e.g., phase changes) processes is presented. The available energy is defined relative ... -
The Impact of Model Resolution on Differences between Independent Column Approximation and Monte Carlo Estimates of Shortwave Surface Irradiance and Atmospheric Heating Rate
(American Meteorological Society, 2005)Within general circulation models (GCMs), domain average radiative fluxes are computed using plane-parallel radiative transfer algorithms that rely on cloud overlap schemes to account for clouds not resolved at the horizontal ... -
Some Effects of Model Resolution on Simulated Gravity Waves Generated by Deep, Mesoscale Convection
(American Meteorological Society, 2005)Over the past decade, numerous numerical modeling studies have shown that deep convective clouds can produce gravity waves that induce a significant vertical flux of horizontal momentum. Such studies used models with ...
