Internal Interannual Variability of the Troposphere–Stratosphere Coupled System in a Simple Global Circulation Model. Part II: Millennium Integrations
(American Meteorological Society, 2002)A pair of millennium (1000 yr) integrations with a simple global circulation model under the same conditions as in Part I of this paper are performed for further statistical analyses on internal intraseasonal and interannual ... -
Wind Stress Simulations and the Equatorial Momentum Budget in an AGCM
(American Meteorological Society, 2002)A detailed examination of the atmospheric momentum budget over the equatorial Pacific and its relation to oceanic wind stresses is undertaken using the results of a 20-yr (1979?99), forced-SST, AGCM experiment. The results ... -
Entrainment and Decoupling Relations for Cloudy Boundary Layers
(American Meteorological Society, 2002)An idealized model of the relationship between entrainment in cloud-topped boundary layers, circulation structure, and the degree of decoupling between the cloud and subcloud layers is developed based on simple turbulent ... -
Nonhydrostatic, Three-Dimensional Perturbations to Balanced, Hurricane-like Vortices. Part I: Linearized Formulation, Stability, and Evolution
(American Meteorological Society, 2002)In this paper, the first of two parts, the dynamics of linearized perturbations to hurricane-like vortices are studied. Unlike previous studies, which are essentially two-dimensional or assume that the perturbations are ... -
Dynamics of Low-Frequency Variability: Barotropic Mode
(American Meteorological Society, 2002)The dynamics of low-frequency variability is investigated in terms of sensitivity to the dependence of its relative zonal position of a single storm track in a simplified global circulation model. A streamfunction tendency ... -
Strong Mixing Events Observed near the Tropopause with the MU Radar and High-Resolution Balloon Techniques
(American Meteorological Society, 2002)In the present paper, strong isotropic radar echo enhancements are shown that are related to the existence of nearly statically neutralized layers (40?120 m thick) observed with high-resolution (10 cm) temperature measurements ... -
Retrieval of Surface Solar Radiation Budget under Ice Cloud Sky: Uncertainty Analysis and Parameterization
(American Meteorological Society, 2002)This study investigates and accounts for the influence of various ice cloud parameters on the retrieval of the surface solar radiation budget (SSRB) from reflected flux at the top of the atmosphere (TOA). The optical ... -
Generation of Moving Spiral Bands in Tropical Cyclones
(American Meteorological Society, 2002)A theory based on the shallow water equation is developed to explain the generation of moving spiral-banded structures in tropical cyclones. The theory proposes that fluctuation of the vorticity distribution in the compact ... -
Area-Average Solar Radiative Transfer in Three-Dimensionally Inhomogeneous Clouds: The Independently Scattering Cloudlet Model
(American Meteorological Society, 2002)A new conceptual and computational basis is described for renormalizing the single-scatter and extinction properties (optical depth, single-scatter albedo, and scattering phase function or asymmetry parameter) of a ... -

Effect of the Hadley Circulation on the Reflection of Planetary Waves in Three-Dimensional Tropospheric Flows
(American Meteorological Society, 2002)The nonlinear behavior of quasi-stationary planetary waves excited by midlatitude orographic forcing is considered in a three-dimensional primitive equation model that includes a representation of the Hadley circulation. ... -

Probabilistic Stability of an Atmospheric Model to Various Amplitude Perturbations
(American Meteorological Society, 2002)Every forecast should include an estimate of its likely accuracy, as a measure of predictability. A new measure, the first passage time (FPT), which is defined as the time period when the model error first exceeds a ... -
An Empirical Normal Mode Diagnostic Algorithm Applied to NCEP Reanalyses
(American Meteorological Society, 2002)A diagnostic algorithm, based on the empirical normal mode decomposition technique, is proposed as a diagnostic tool in studies of the atmospheric variability. It begins by analyzing the transient eddies in terms of empirical ... -

The Advection–Diffusion Problem for Stratospheric Flow. Part II: Probability Distribution Function of Tracer Gradients
(American Meteorological Society, 2002)This paper is a continuation of the study of the advection?diffusion problem for stratospheric flow, and deals with the probability distribution function (PDF) of gradients of a freely decaying passive tracer. Theoretical ... -
Runaway Greenhouse Effect in a Semigray Radiative–Convective Model
(American Meteorological Society, 2002)The effects of the nongray absorption (i.e., atmospheric opacity varying with wavelength) on the possible upper bound of the outgoing longwave radiation (OLR) emitted by a planetary atmosphere have been examined. This ... -
Layered Structure Associated with Low Potential Vorticity near the Tropopause Seen in High-Resolution Radiosondes over Japan
(American Meteorological Society, 2002)Horizontal wind and temperature data obtained from operational radiosondes over Japan have recently been available with high vertical resolution. Analyzing these data over 4 yr has indicated horizontal velocity layers with ... -
Genesis of Intraseasonal Oscillations and Equatorial Waves
(American Meteorological Society, 2002)The particular role of evaporation?wind feedback, and as well cumulus convection and dissipation, in the formation of the Madden?Julian 30?60-day intraseasonal oscillation (MJO) and equatorially trapped waves, including ... -
Wave-Driven Mean Tropical Upwelling in the Lower Stratosphere
(American Meteorological Society, 2002)The mean meridional circulation induced by zonal momentum forcing is considered in the context of (i) a wave?mean model, in which the momentum forcing arises naturally from the explicit representation of the stratospheric ...
