Mechanism of Concentric Eyewall Replacement Cycles and Associated Intensity Change
(American Meteorological Society, 2011)o understand the mechanisms responsible for the secondary eyewall replacement cycles and associated intensity changes in intense tropical cyclones (TCs), two numerical experiments are conducted in this study with the Weather ... -
An Integrated TKE-Based Eddy Diffusivity/Mass Flux Boundary Layer Closure for the Dry Convective Boundary Layer
(American Meteorological Society, 2011)his study presents a new approach to the eddy diffusivity/mass flux (EDMF) framework for the modeling of convective boundary layers. At the root of EDMF lies a decomposition of turbulent transport mechanisms into strong ... -
Moist versus Dry Barotropic Instability in a Shallow-Water Model of the Atmosphere with Moist Convection
(American Meteorological Society, 2011)ynamical influence of moist convection upon development of the barotropic instability is studied in the rotating shallow-water model. First, an exhaustive linear ?dry? stability analysis of the Bickley jet is performed, ... -
Estimating the Ice Crystal Enhancement Factor in the Tropics
(American Meteorological Society, 2011)he ice crystal enhancement (IE) factor, defined as the ratio of the ice crystal to ice nuclei (IN) number concentrations for any particular cloud condition, is needed to quantify the contribution of changes in IN to global ... -
Polarimetric Doppler Radar Observations of Kelvin–Helmholtz Waves in a Winter Storm
(American Meteorological Society, 2011)elvin?Helmholtz waves were observed by the Twin Lakes, Oklahoma (KTLX), Weather Surveillance Radar-1988 Doppler (WSR-88D); the Norman, Oklahoma (KOUN), polarimetric WSR-88D; and the polarimetric Collaborative Adaptive ... -
Simple Multicloud Models for the Diurnal Cycle of Tropical Precipitation. Part I: Formulation and the Case of the Tropical Oceans
(American Meteorological Society, 2011)he variation of tropical precipitation due to the diurnal cycle of solar heating is examined here in the context of two simple models for tropical convection. The models utilize three cloud types?congestus, deep, and ... -
Baroclinic Stationary Waves in Aquaplanet Models
(American Meteorological Society, 2011)n aquaplanet model is used to study the nature of the highly persistent low-frequency waves that have been observed in models forced by zonally symmetric boundary conditions.Using the Hayashi spectral analysis of the ... -
Instability of Shielded Surface Temperature Vortices
(American Meteorological Society, 2011)he stability characteristics of the surface quasigeostrophic shielded Rankine vortex are found using a linearized contour dynamics model. Both the normal modes and nonmodal evolution of the system are analyzed and the ... -
Trade Wind Cloud Evolution Observed by Polarization Radar: Relationship to Giant Condensation Nuclei Concentrations and Cloud Organization
(American Meteorological Society, 2011)hallow marine trade wind cumuli are one of the most prevalent cloud types in the tropical atmosphere. Understanding how precipitation forms within these clouds is necessary to advance our knowledge concerning their role ... -
Toward a Physical Characterization of Raindrop Collision Outcome Regimes
(American Meteorological Society, 2011)comprehensive raindrop collision outcome regime diagram that delineates the physical conditions associated with the outcome regimes (i.e., bounce, coalescence, and different breakup types) of binary raindrop collisions is ... -

The Static Stability of the Tropopause Region in Adiabatic Baroclinic Life Cycle Experiments
(American Meteorological Society, 2010)he tropopause inversion layer (TIL) is a region of enhanced static stability just above the WMO-defined thermal tropopause. It is a ubiquitous feature in midlatitudes and is well characterized by observations. However, it ... -

Atmospheric Local Energetics and Energy Interactions between Mean and Eddy Fields. Part I: Theory
(American Meteorological Society, 2010)new diagnostic scheme for the atmospheric local energetics is proposed. In contrast to conventional schemes, this scheme correctly represents the local features of the Lorenz energy cycle for time-mean and transient-eddy ... -
High-Resolution Simulation of the Electrification and Lightning of Hurricane Rita during the Period of Rapid Intensification
(American Meteorological Society, 2010)In this paper, a high-resolution simulation establishing relationships between lightning and eyewall convection during the rapid intensification phase of Rita will be highlighted. The simulation is an attempt to relate ... -
Impact of Two-Way Aerosol–Cloud Interaction and Changes in Aerosol Size Distribution on Simulated Aerosol-Induced Deep Convective Cloud Sensitivity
(American Meteorological Society, 2011)ecent cloud-resolving model studies of single (isolated) deep convective clouds have shown contradicting results regarding the response of the deep convection to changes in the aerosol concentration. In the present study, ... -
Convective Boundary Layers Driven by Nonstationary Surface Heat Fluxes
(American Meteorological Society, 2010)n this study the response of dry convective boundary layers to nonstationary surface heat fluxes is systematically investigated. This is relevant not only during sunset and sunrise but also, for example, when clouds modulate ... -
The Mean State of Axisymmetric Hurricanes in Statistical Equilibrium
(American Meteorological Society, 2010)umerical experiments are performed to determine the mean state of an axisymmetric hurricane in statistical equilibrium. Most earlier studies used a damping scheme on the temperature field as a parameterization of radiative ...
