Efficacy of climate forcings
[1] We use a global climate model to compare the effectiveness of many climate forcing agents for producing climate change. We find a substantial range in the “efficacy” of different forcings, whereExpand

Ocean Turbulence I: One-Point Closure Model Momentum and Heat Vertical Diffusivities
Since the early forties, one-point turbulence closure models have been the canonical tools used to describe turbulent flows in many fields. In geophysics, Mellor and Yamada applied such models usingExpand

Present-Day Atmospheric Simulations Using GISS ModelE: Comparison to In Situ, Satellite, and Reanalysis Data
Abstract A full description of the ModelE version of the Goddard Institute for Space Studies (GISS) atmospheric general circulation model (GCM) and results are presented for present-day climateExpand

An Improved Model for the Turbulent PBL
Abstract Second-order turbulence models of the Mellor and Yamada type have been widely used to simulate the planetary boundary layer (PBL). It is, however, known that these models have severalExpand

Configuration and Assessment of the GISS ModelE2 Contributions to the CMIP5 Archive
We present a description of the ModelE2 version of the Goddard Institute for Space Studies (GISS) General Circulation Model (GCM) and the configurations used in the simulations performed for theExpand

Stellar Turbulent Convection: A Self-consistent Model
We present a self-consistent model for stellar turbulent convection that is similar in spirit to the CM model (Canuto & Mazzitelli 1991) since it accounts for the full spectrum of the turbulentExpand

Stellar Turbulent Convection: A New Model and Applications
Improvements of the mixing-length theory (MLT) of turbulent convection in stellar atmospheres are developed theoretically. It is pointed out that inaccuracies are introduced into MLT by theExpand

Ocean Turbulence. Part II: Vertical Diffusivities of Momentum, Heat, Salt, Mass, and Passive Scalars
Abstract A Reynolds stress–based model is used to derive algebraic expressions for the vertical diffusivities Kα(α = m, h, s) for momentum, heat, and salt. The diffusivities are expressed as Kα(Rρ,Expand

Determination of the Smagorinsky–Lilly constant CS
The Smagorinsky–Lilly (SL) SGS model νt=(CSΔ)2S yields a constant CS=0.20–0.22 which is a factor of 2 larger than what is needed in LES calculations; in addition, Deardorff and Hunt et al. suggestedExpand

Dangerous human-made interference with climate: a GISS modelE study
We investigate the issue of "dangerous human-made interference with climate" using simulations with GISS modelE driven by measured or estimated forcings for 1880–2003 and extended to 2100 for IPCCExpand
