Atmospheric Entropy. Part I: Climate Dissipation Structure
Publisher: American Meteorological Society
Abstract: tmospheric entropy and its association with climate dissipation are investigated. The balance equation for entropy is derived through the mean and transient thermal and moisture equations. The entropy production contains ...
Doubling–Adding Method for Delta-Four-Stream Spherical Harmonic Expansion Approximation in Radiative Transfer Parameterization
Publisher: American Meteorological Society
Abstract: hough the single-layer solutions have been found for the δ-four-stream spherical harmonic expansion method (SHM) in radiative transfer, there is lack of a corresponding doubling?adding method (4SDA), which enables the ...
Entropy Evolution Characteristics Associated with the Development of the South Asian Monsoon
Publisher: American Meteorological Society
Abstract: he structure and evolution characteristics of atmospheric entropy production associated with the climatologic monsoon onset and evolution were investigated using the National Centers for Environmental Prediction (NCEP) ...
Correlated k-Distribution Treatment of Cloud Optical Properties and Related Radiative Impact
Publisher: American Meteorological Society
Abstract: new scheme of water cloud optical properties is proposed for correlated k-distribution (CKD) models, in which the correlation in spectral distributions between the gaseous absorption coefficient and cloud optical properties ...
The Dissipation Structure of Extratropical Cyclones
Publisher: American Meteorological Society
Abstract: he physical characteristics of extratropical cyclones are investigated based on nonequilibrium thermodynamics. Nonequilibrium thermodynamics, using entropy as its main tool, has been widely used in many scientific fields. ...
Analytical Delta-Four-Stream Doubling–Adding Method for Radiative Transfer Parameterizations
Publisher: American Meteorological Society
Abstract: lthough single-layer solutions have been obtained for the δ-four-stream discrete ordinates method (DOM) in radiative transfer, a four-stream doubling?adding method (4DA) is lacking, which enables us to calculate the radiative ...
Accounting for Several Infrared Radiation Processes in Climate Models
Publisher: American Meteorological Society
Abstract: AbstractThree aspects of longwave (LW) radiation processes are investigated using numerical experiments with the Canadian Atmospheric Global Climate Model version 4.3 (CanAM4.3). These are the overlapping LW and shortwave ...
Variational Iteration Method for Infrared Radiative Transfer in a Scattering Medium
Publisher: American Meteorological Society
Abstract: AbstractA new scheme is proposed for using the variational iteration method (VIM) to solve the problem of infrared radiative transfer in a scattering medium. This scheme allows the zeroth-order solution to be identified ...
Analytical Infrared Delta-Four-Stream Adding Method from Invariance Principle
Publisher: American Meteorological Society
Abstract: he single-layer solutions using a four-stream discrete ordinates method (DOM) in infrared radiative transfer (IRT) have been obtained. Two types of thermal source assumptions?Planck function exponential and linear dependence ...
Estimation of Errors in Two-Stream Approximations of the Solar Radiative Transfer Equation for Cloudy-Sky Conditions
Publisher: American Meteorological Society
Abstract: olar flux densities and heating rates predicted by a broadband, multilayer δ-Eddington two-stream approximation are compared to estimates from a Monte Carlo model that uses detailed descriptions of cloud particle phase ...
