A Gray-Radiation Aquaplanet Moist GCM. Part I: Static Stability and Eddy Scale
(American Meteorological Society, 2006)In this paper, a simplified moist general circulation model is developed and used to study changes in the atmospheric general circulation as the water vapor content of the atmosphere is altered. The key elements of the ... -
Evaporation and Precipitation Surface Effects in Local Mass Continuity Laws of Moist Air
(American Meteorological Society, 2006)The local mass balance equations of cloudy air are formulated for a model system composed of dry air, water vapor, and four categories of water condensate particles, as typically adopted for numerical weather prediction ... -

Three MCS Cases Occurring in Different Synoptic Environments in the Sub-Sahelian Wet Zone during the 2002 West African Monsoon
(American Meteorological Society, 2006)Three mesoscale convective systems (MCSs) occurring in the sub-Sahelian wet zone of West Africa are examined using observations from the 2002 Integrated Approach to the Efficient Management of Scarce Water Resources in ... -
Observed Boundary Layer Wind Structure and Balance in the Hurricane Core. Part I: Hurricane Georges
(American Meteorological Society, 2006)The GPS dropsonde allows observations at unprecedentedly high horizontal and vertical resolution, and of very high accuracy, within the tropical cyclone boundary layer. These data are used to document the boundary layer ... -
Dynamic Adjustment in a Numerically Simulated Mesoscale Convective System: Impact of the Velocity Field
(American Meteorological Society, 2006)An identical twin methodology is applied to a three-dimensional cloud model to study the dynamics of adjustment in deep convective storms. The principal goal is to diagnose how mass and velocity fields mutually adjust in ... -
Observed Boundary Layer Wind Structure and Balance in the Hurricane Core. Part II: Hurricane Mitch
(American Meteorological Society, 2006)Part I of this paper presented a detailed analysis of the boundary layer of Hurricane Georges (1998), based mainly on the newly available high-resolution GPS dropsonde data. Here, similar techniques and data are used to ... -
Simultaneous Determination of Aerosol and Thin Cirrus Optical Depths over Oceans from MODIS Data: Some Case Studies
(American Meteorological Society, 2006)The importance of separating thin cirrus and aerosols from satellite remote sensing to produce broader and more accurate fields for the determination of respective radiative forcings is highlighted. This has been accomplished ... -
Nature of the Differences in the Intraseasonal Variability of the Pacific and Atlantic Storm Tracks: A Diagnostic Study
(American Meteorological Society, 2006)On the basis of an intraseasonal variability index of storm track evaluated for 40 winters (1963?64 through 2003?04) of NCEP?NCAR reanalysis data, it is found that well-defined midwinter minimum [MWMIN; (midwinter maximum ... -
Numerical Simulation of Dust Lifting within Dust Devils—Simulation of an Intense Vortex
(American Meteorological Society, 2006)Based on an advanced dust devil?scale large-eddy simulation (LES) model, the atmosphere flow of a modeled dust devil in a quasi?steady state was first simulated to illustrate the characteristics of the gas phase field in ... -

A Generalized Momentum Framework for Looking at Baroclinic Circulations
(American Meteorological Society, 2006)This paper introduces the concept of potential momentum, which is a nonlocal measure of the thermal structure that has momentum units. Physically, it may be interpreted as the zonal momentum that the flow would realize ... -
On the Role of Clouds and Moisture in Tropical Waves: A Two-Dimensional Model Study
(American Meteorological Society, 2006)Observations show that convective perturbations of the tropical atmosphere are associated with substantial variations of clouds and water vapor. Recent studies suggest that these variations may play an active role in the ... -
Three-Dimensional Structure and Dynamics of African Easterly Waves. Part I: Observations
(American Meteorological Society, 2006)The mean structure of African easterly waves (AEWs) over West Africa and the adjacent Atlantic is isolated by projecting dynamical fields from reanalysis and radiosonde data onto space?time-filtered satellite-derived ... -
Data Assimilation as Synchronization of Truth and Model: Experiments with the Three-Variable Lorenz System
(American Meteorological Society, 2006)The potential use of chaos synchronization techniques in data assimilation for numerical weather prediction models is explored by coupling a Lorenz three-variable system that represents ?truth? to another that represents ... -
Three-Dimensional Structure and Dynamics of African Easterly Waves. Part II: Dynamical Modes
(American Meteorological Society, 2006)A primitive equation model is used to study the linear normal modes of the African easterly jet (AEJ). Reanalysis data from the summertime mean (June?September; JJAS) flow is used to provide zonally uniform and wavy basic ... -
Impact of Explicit Atmosphere–Ocean Coupling on MJO-Like Coherent Structures in Idealized Aquaplanet Simulations
(American Meteorological Society, 2006)This paper discusses the impact of the atmosphere?ocean coupling on the large-scale organization of tropical convection simulated by an idealized global model applying the Cloud-Resolving Convection Parameterization (CRCP; ... -
Tropical Cyclone Initialization and Prediction Based on Four-Dimensional Variational Data Assimilation
(American Meteorological Society, 2006)Issues on the initialization and simulation of tropical cyclones (TCs) have been studied here based on four-dimensional variational data assimilation. In particular, experiments have been carried out to assess 1) what the ... -
Observational Analysis of a Gust Front to Bore to Solitary Wave Transition within an Evolving Nocturnal Boundary Layer
(American Meteorological Society, 2006)The evolution of a gust front to bore to solitary wave transition, and comprehensive information on the evolving nocturnal boundary layer (NBL) associated with this change, are described with analysis of radar and profiler ... -
