The Response of the ITCZ to Extratropical Thermal Forcing: Idealized Slab-Ocean Experiments with a GCM
Using a comprehensive atmospheric GCM coupled to a slab mixed layer ocean, experiments are performed to study the mechanism by which displacements of the intertropical convergence zone (ITCZ) are
Less Than 2 °C Warming by 2100 Unlikely
A country-specific version of Kaya’s identity is used to develop a statistically-based probabilistic forecast of CO2 emissions and temperature change to 2100, and a joint Bayesian hierarchical model for GDP per capita and carbon intensity is developed.
Response of the Zonal Mean Atmospheric Circulation to El Niño versus Global Warming
Abstract The change in the zonal mean atmospheric circulation under global warming is studied in comparison with the response to El Nino forcing, by examining the model simulations conducted for the
Link between the double-Intertropical Convergence Zone problem and cloud biases over the Southern Ocean
It is found that cloud biases over the Southern Ocean explain most of the model-to-model differences in the amount of excessive precipitation in Southern Hemisphere tropics, and are suggested to be responsible for this aspect of the double-ITCZ problem in most global climate models.
A Gray-Radiation Aquaplanet Moist GCM. Part I: Static Stability and Eddy Scale
Abstract In this paper, a simplified moist general circulation model is developed and used to study changes in the atmospheric general circulation as the water vapor content of the atmosphere is
The Dynamics of Idealized Convection Schemes and Their Effect on the Zonally Averaged Tropical Circulation
In this paper, the effect of a simple convection scheme on the zonally averaged tropical general circulation is examined within an idealized moist GCM to obtain broad classifications of the influence
For pulsars similar to the one in the Crab Nebula, most of the energy input to the surrounding wind nebula occurs on a timescale 103 yr; during this time, the nebula expands into freely expanding
The Tropical Response to Extratropical Thermal Forcing in an Idealized GCM: The Importance of Radiative Feedbacks and Convective Parameterization
Abstract The response of tropical precipitation to extratropical thermal forcing is reexamined using an idealized moist atmospheric GCM that has no water vapor or cloud feedbacks, simplifying the
Anthropogenic sulfate aerosol and the southward shift of tropical precipitation in the late 20th century
[1] In this paper, we demonstrate a global scale southward shift of the tropical rain belt during the latter half of the 20th century in observations and global climate models (GCMs). In rain gauge
Width of the Hadley cell in simple and comprehensive general circulation models
The width of the Hadley cell is studied over a wide range of climate regimes using both simple and comprehensive atmospheric general circulation models. Aquaplanet, fixed sea surface temperature
