Speciation of Organic Aerosols in the Tropical Mid-Pacific and Their Relationship to Light Scattering
(American Meteorological Society, 2004)Although the importance of the aerosol contribution to the global radiative budget has been recognized, the forcings of aerosols in general, and specifically the role of the organic component in these forcings, still contain ... -
Mixing Layer Formation near the Tropopause Due to Gravity Wave–Critical Level Interactions in a Cloud-Resolving Model
(American Meteorological Society, 2004)A plausible mechanism for the formation of mixing layers in the lower stratosphere above regions of tropical convection is demonstrated numerically using high-resolution, two-dimensional (2D), anelastic, nonlinear, ... -
Solar Radiation Budget from the MRI Radiometers for Clear and Cloudy Air Columns within ARESE II
(American Meteorological Society, 2004)As an international collaborative research activity within the Japanese Cloud-Climate Study (JACCS) program, the authors participated in the second Atmospheric Radiation Measurement (ARM) Enhanced Shortwave Experiment ... -
The Diurnal Cycle of Convection and Atmospheric Tides in an Aquaplanet GCM
(American Meteorological Society, 2004)The diurnal cycle of tropical convection and its relationship to the atmospheric tides is investigated using an aquaplanet GCM. The diurnal and semidiurnal harmonics of precipitation are both found to contribute significantly ... -
Full-Spectrum Correlated-k Distribution for Shortwave Atmospheric Radiative Transfer
(American Meteorological Society, 2004)The full-spectrum correlated k-distribution (FSCK) method, originally developed for applications in combustion systems, is adapted for use in shortwave atmospheric radiative transfer. By weighting k distributions by the ... -
The Formation of Concentric Vorticity Structures in Typhoons
(American Meteorological Society, 2004)An important issue in the formation of concentric eyewalls in a tropical cyclone is the development of a symmetric structure from asymmetric convection. It is proposed herein, with the aid of a nondivergent barotropic ... -
Wave Response during Hydrostatic and Geostrophic Adjustment. Part I: Transient Dynamics
(American Meteorological Society, 2005)The adjustment of a compressible, stably stratified atmosphere to sources of hydrostatic and geostrophic imbalance is investigated using a linear model. Imbalance is produced by prescribed, time-dependent injections of ... -
The Effect of Wind Shear and Curvature on the Gravity Wave Drag Produced by a Ridge
(American Meteorological Society, 2004)The analytical model proposed by Teixeira, Miranda, and Valente is modified to calculate the gravity wave drag exerted by a stratified flow over a 2D mountain ridge. The drag is found to be more strongly affected by the ... -
Radiative Heat Transfer Analysis within Three-Dimensional Clouds Subjected to Solar and Sky Irradiation
(American Meteorological Society, 2004)A three-dimensional radiative heat transfer analysis of an arbitrary-shaped modeled cloud subjected to solar and sky irradiation has been performed. The Radiation Element Method by Ray Emission Model (REM2) was used for ... -
Phase Alignment of the Tropical Stratospheric QBO in the Annual Cycle
(American Meteorological Society, 2004)This paper investigates the occurrence of phase alignment of the tropical stratospheric quasi-biennial oscillation (QBO) with the annual cycle. First, updating previous studies, observational results are shown for NCEP ... -
Aerosol Properties and Chemical Apportionment of Aerosol Optical Depth at Locations off the U.S. East Coast in July and August 2001
(American Meteorological Society, 2005)Airborne in situ measurements of vertical profiles of the aerosol light scattering coefficient, light absorption coefficient, and single scattering albedo (?0) are presented for locations off the East Coast of the United ... -
Quasi-Periodic Variations of the Polar Vortex in the Southern Hemisphere Stratosphere Due to Wave–Wave Interaction
(American Meteorological Society, 2004)The winter polar vortex in the Southern Hemisphere stratosphere is characterized by prominent quasi-stationary planetary waves: zonal wavenumber 1 (wave 1) and the eastward-traveling wave (wave 2). Quasi-periodic variations ... -
The Theory of Ice Nucleation by Heterogeneous Freezing of Deliquescent Mixed CCN. Part I: Critical Radius, Energy, and Nucleation Rate
(American Meteorological Society, 2004)This paper extends previous work on the theory of heterogenous ice nucleation. The goals of this analysis are to explain empirical observations of ice nucleation and to provide a suitable framework for modeling and ... -
Simulation of Effects of Atmospheric Aerosols on Deep Turbulent Convective Clouds Using a Spectral Microphysics Mixed-Phase Cumulus Cloud Model. Part II: Sensitivity Study
(American Meteorological Society, 2004)Effects of different size distributions of cloud condensational nuclei (CCN) on the evolution of deep convective clouds under dry unstable continental thermodynamic conditions are investigated using the spectral microphysics ... -

Sensitivity of Perturbation Variance and Fluxes in Turbulent Jets to Changes in the Mean Jet
(American Meteorological Society, 2004)Synoptic-scale eddy variance and fluxes of heat and momentum in midlatitude jets are sensitive to small changes in mean jet velocity, dissipation, and static stability. In this work the change in the jet producing the ... -

A Barotropic Envelope Rossby Soliton Model for Block–Eddy Interaction. Part II: Role of Westward-Traveling Planetary Waves
(American Meteorological Society, 2005)The role of westward-traveling planetary waves in the block onset and the deformation of eddies during the interaction between synoptic-scale eddies and an incipient block is first examined by constructing an incipient ... -
Cloud Timescales and Orographic Precipitation
(American Meteorological Society, 2003)Orographic precipitation is studied by analyzing the sensitivity of numerical simulations to variations in mountain height, width, and wind speed. The emphasis is on upslope lifting over isolated mountains in cold climates. ... -
The Seasonal Cycle of Interannual Variability and the Dynamical Imprint of the Seasonally Varying Mean State
(American Meteorological Society, 2003)Various aspects of the seasonal cycle of interannual variability of the observed 300-hPa streamfunction are documented and related to dynamical influences of the seasonality of the mean circulation. The stochastically ...
