Stratospheric Temperature and Radiative Forcing Response to 11-Year Solar Cycle Changes in Irradiance and Ozone
(American Meteorological Society, 2009)The 11-yr solar cycle temperature response to spectrally resolved solar irradiance changes and associated ozone changes is calculated using a fixed dynamical heating (FDH) model. Imposed ozone changes are from satellite ... -
Inertial Particle Dynamics in a Hurricane
(American Meteorological Society, 2009)The motion of inertial (i.e., finite-size) particles is analyzed in a three-dimensional unsteady simulation of Hurricane Isabel. As established recently, the long-term dynamics of inertial particles in a fluid is governed ... -
Response of Idealized Baroclinic Wave Life Cycles to Stratospheric Flow Conditions
(American Meteorological Society, 2009)Dynamical stratosphere?troposphere coupling through a response of baroclinic waves to lower stratospheric flow conditions is investigated from an initial value approach. A series of adiabatic and frictionless nonlinear ... -

Parameterization of Cloud Drop Activation Based on Analytical Asymptotic Solutions to the Supersaturation Equation
(American Meteorological Society, 2009)Toward improving parameterization of cloud droplet activation in cloud and climate models, the integro?differential equation for supersaturation is solved analytically for the algebraic size spectrum of the cloud condensation ... -
Effects of Moist Convection on Hurricane Predictability
(American Meteorological Society, 2009)This study exemplifies inherent uncertainties in deterministic prediction of hurricane formation and intensity. Such uncertainties could ultimately limit the predictability of hurricanes at all time scales. In particular, ... -
Nonlinear Representation of the Quasi-Biennial Oscillation
(American Meteorological Society, 2009)A nonlinear principal component analysis (NLPCA) is applied to monthly mean zonal wind observations from January 1956 through December 2007 taken at seven pressure levels between 10 and 70 hPa in the stratosphere near the ... -

On Robust Estimation of Low-Frequency Variability Trends in Discrete Markovian Sequences of Atmospheric Circulation Patterns
(American Meteorological Society, 2009)Identification and analysis of temporal trends and low-frequency variability in discrete time series is an important practical topic in the understanding and prediction of many atmospheric processes, for example, in analysis ... -
Two Comments on the Surface Quasigeostrophic Model for the Atmospheric Energy Spectrum
(American Meteorological Society, 2009)The horizontal wavenumber spectra of wind and temperature in the upper troposphere and lower stratosphere display a narrow k?3 range at scales on the order of 1000 km and a broad k?5/3 range at mesoscales on the order of ... -
Baroclinic Instability in the Eady Model: Interpretations
(American Meteorological Society, 2009)The mechanism of baroclinic instability in the Eady model is interpreted by explicitly calculating the ageostrophic circulations related to the model?s hyperbolic basic functions. It is advantageous to perform the analysis ... -
Nonlinear Saturation of Vertically Propagating Rossby Waves
(American Meteorological Society, 2009)The interaction between vertical Rossby wave propagation and wave breaking is studied in the idealized context of a beta-plane channel model. Considering the problem of propagation through a uniform zonal flow in an ... -
What Controls the Transition from Shallow to Deep Convection?
(American Meteorological Society, 2009)In this study, a 2D cloud-system-resolving model (CSRM) is used to assess the control mechanism for the transition from shallow to deep convection in the diurnal cycle over land. By comparing with a 3D CSRM under conditions ... -
The Effect of Imposed Drying on Parameterized Deep Convection
(American Meteorological Society, 2009)This paper examines the influence of imposed drying, intended to represent horizontal advection of dry air, on parameterized deep convection interacting with large-scale dynamics in a single-column model framework. Two ... -
A Note on the Numerical Representation of Surface Dynamics in Quasigeostrophic Turbulence: Application to the Nonlinear Eady Model
(American Meteorological Society, 2009)The quasigeostrophic equations consist of the advection of linearized potential vorticity coupled with advection of temperature at the bounding upper and lower surfaces. Numerical models of quasigeostrophic flow often ... -
Observations and Numerical Simulations of Subrotor Vortices during T-REX
(American Meteorological Society, 2009)High-resolution observations from scanning Doppler and aerosol lidars, wind profiler radars, as well as surface and aircraft measurements during the Terrain-induced Rotor Experiment (T-REX) provide the first comprehensive ... -
Orographic Precipitation in the Tropics: Experiments in Dominica
(American Meteorological Society, 2009)The ?natural laboratory? of mountainous Dominica (15°N) in the trade wind belt is used to study the physics of tropical orographic precipitation in its purest form, unforced by weather disturbances or by the diurnal cycle ... -
Effect of Latitudinal Variations in Low-Level Baroclinicity on Eddy Life Cycles and Upper-Tropospheric Wave-Breaking Processes
(American Meteorological Society, 2009)An analysis of the potential vorticity gradient and the refractive index in quasigeostrophic (QG) flows on the sphere reveals that the absolute vorticity and the stretching parts have two contradictory effects on the ...
