Abstract: A hierarchy of zonally averaged atmospheric models is used to study the role of mean meridional motions and large-scale eddies in determining the zonal climate. Five models are developed: a radiative-convective equilibrium ...

Abstract: The traditional method of estimating cyclone frequency by counting the number of storms passing through latitude-longitude grid cells is known to be biased because it effectively overweights the lower latitudes. Here we ...

Abstract: Vertical finite-differences schemes that preserve the important integral properties of the continuum equations are derived for the basic hydrodynamic and thermodynamic equations governing the atmosphere. The vertical ...

Abstract: A set of general circulation model simulations is analyzed to determine how cloud distribution and cloud radiative properties might change as climate warms and to isolate and quantify the various feedback effects of clouds ...

Abstract: A simple technique is proposed for calculating global mean climate forcing from transient integrations of coupled atmosphere?ocean general circulation models (AOGCMs). This ?climate forcing? differs from the conventionally ...

Abstract: phase of the Coupled Model Intercomparison Project (CMIP5) will produce a state-of-the- art multimodel dataset designed to advance our knowledge of climate variability and climate change. Researchers worldwide are analyzing ...

Abstract: AbstractAnthropogenic climate change is predicted to cause spatial and temporal shifts in precipitation patterns. These may be apparent in changes to the annual cycle of zonal mean precipitation P. Trends in the amplitude ...

Abstract: his study clarifies the causes of intermodel differences in the global-average temperature response to doubled CO2, commonly known as equilibrium climate sensitivity (ECS). The authors begin by noting several issues with ...

Abstract: eproducing characteristics of observed sea ice extent remains an important climate modeling challenge. This study describes several approaches to improve how model biases in total sea ice distribution are quantified, and ...
