(American Meteorological Society, 2011) -
Moist Recirculation and Water Vapor Transport on Dry Isentropes
(American Meteorological Society, 2011)n analysis of the overturning circulation in dry isentropic coordinates using reanalysis data is presented. The meridional mass fluxes on surfaces of constant dry potential temperature but distinct equivalent potential ... -
Retrieval of Aerosol Optical Depth above Clouds from OMI Observations: Sensitivity Analysis and Case Studies
(American Meteorological Society, 2011)large fraction of the atmospheric aerosol load reaching the free troposphere is frequently located above low clouds. Most commonly observed aerosols above clouds are carbonaceous particles generally associated with biomass ... -
The Impact of Size Sorting on the Polarimetric Radar Variables
(American Meteorological Society, 2012)ifferential sedimentation of precipitation occurs because heavier hydrometeors fall faster than lighter ones. Updrafts and vertical wind shear can maintain this otherwise transient size sorting, resulting in prolonged ... -
Influence of the Valley Surroundings on Valley Wind Dynamics
(American Meteorological Society, 2011)n a recent study, the authors investigated the mechanisms leading to the formation of diurnal along-valley winds in a valley formed by two isolated mountain ridges on a horizontal plain. The main focus was on the relation ... -
A Modeling Study on the Development of a Bowing Structure and Associated Rear Inflow within a Squall Line over South China
(American Meteorological Society, 2012)hrough convection-permitting simulations, this study examines a large bowing structure within a squall line that occurred during the rainy season in South China. The bowing structure is closely associated with a local ... -
Equatorial Planetary Waves and Their Signature in Atmospheric Variability
(American Meteorological Society, 2011)quatorial planetary waves are a fundamental component of the tropical climate system. Previous studies have examined their structure in the climatological-mean circulation, their role in the climatological-mean momentum ... -
A Model for the Interaction between 2-Day Waves and Moist Kelvin Waves
(American Meteorological Society, 2011)he eastward-propagating tropical low-frequency disturbances, such as the moist Kelvin waves or the Madden?Julian oscillation (MJO), are often observed to experience convective enhancement when meeting with the westward-propagating ... -
Mesoscale Analysis of Heavy Rainfall Episodes from SoWMEX/TiMREX
(American Meteorological Society, 2011)he authors analyze the mesoscale structure accompanying two multiday periods of heavy rainfall during the Southwest Monsoon Experiment and the Terrain-Induced Mesoscale Rainfall Experiment conducted over and near Taiwan ... -
Robustness of Dynamical Feedbacks from Radiative Forcing: 2% Solar versus 2 × CO2 Experiments in an Idealized GCM
(American Meteorological Society, 2012)espite the differences in the spatial patterns of the external forcing associated with a doubling CO2 and with a 2% solar variability, the final responses in the troposphere and at the surface in a three-dimensional general ... -
The Usefulness of Piecewise Potential Vorticity Inversion
(American Meteorological Society, 2011)t is today widely accepted that potential vorticity (PV) thinking is a highly useful approach for understanding important aspects of dynamic meteorology and for validation of output from state-of-the-art numerical weather ... -
Experimental Study of Collection Efficiencies between Submicron Aerosols and Cloud Droplets
(American Meteorological Society, 2011)ollection efficiency E experiments for aerosol particles scavenged by cloud droplets were carried out in the newly built Collision Ice Nucleation Chamber (CLINCH). Pure water droplets having radii between 12.8 and 20.0 ?m ... -
An Idealized Semi-Empirical Framework for Modeling the Madden–Julian Oscillation
(American Meteorological Society, 2012)he authors present a simple semi-empirical model to explore the hypothesis that the Madden?Julian oscillation can be represented as a moisture mode destabilized by surface flux and cloud?radiative feedbacks. The model is ... -
Vertical Structure of Tropical Cyclones with Concentric Eyewalls as Seen by the TRMM Precipitation Radar
(American Meteorological Society, 2011)en years of data from the Tropical Rainfall Measurement Mission satellite?s Precipitation Radar are analyzed to determine the typical vertical structure of the concentric eyewalls of tropical cyclones undergoing eyewall ... -
Further Investigation of the Impact of Idealized Continents and SST Distributions on the Northern Hemisphere Storm Tracks

Concentric Eyewall Formation in Typhoon Sinlaku (2008). Part II: Axisymmetric Dynamical Processes
(American Meteorological Society, 2011)n Part I of this study, the association between the secondary eyewall formation (SEF) and the broadening of the outer swirling wind in Typhoon Sinlaku (2008) was documented. The findings from Part I help lay the groundwork ... -
Effect of Aerosol on Circulations and Precipitation in Deep Convective Clouds
(American Meteorological Society, 2012)his study examines the effect of a mesoscale perturbation of aerosol on a larger-scale cloud system driven by deep convective clouds. An aerosol-perturbed domain of size 120 km is prescribed in the middle of the larger-scale ... -
