RISExpansion of the Hadley Cell under Global Warming: Winter versus Summer
Publisher: American Meteorological Society
Abstract: scaling relationship is introduced to explain the seasonality in the outer boundary of the Hadley cell in both climatology and trend in the simulations of phase 3 of the Coupled Model Intercomparison Project (CMIP3). In ...
Dependence of Climate Response on Meridional Structure of External Thermal Forcing
Publisher: American Meteorological Society
Abstract: his study shows that the magnitude of global surface warming greatly depends on the meridional distribution of surface thermal forcing. An atmospheric model coupled to an aquaplanet slab mixed layer ocean is perturbed by ...
The Interannual Relationship between the Latitude of the Eddy-Driven Jet and the Edge of the Hadley Cell
Publisher: American Meteorological Society
Abstract: A strong correlation between the latitudes of the eddy-driven jet and of the Hadley cell edge, on interannual time scales, is found to exist during austral summer, in both the NCEP?NCAR reanalysis and the models participating ...
Sensitivity of Climate Change Induced by the Weakening of the Atlantic Meridional Overturning Circulation to Cloud Feedback
Publisher: American Meteorological Society
Abstract: A variety of observational and modeling studies show that changes in the Atlantic meridional overturning circulation (AMOC) can induce rapid global-scale climate change. In particular, a substantially weakened AMOC leads ...
The Tropical Response to Extratropical Thermal Forcing in an Idealized GCM: The Importance of Radiative Feedbacks and Convective Parameterization
Publisher: American Meteorological Society
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 analysis while retaining the ...
Uncertainty in Climate Change Projections of the Hadley Circulation: The Role of Internal Variability
Publisher: American Meteorological Society
Abstract: he uncertainty arising from internal climate variability in climate change projections of the Hadley circulation (HC) is presently unknown. In this paper it is quantified by analyzing a 40-member ensemble of integrations ...
Sensitivity of Intertropical Convergence Zone Movement to the Latitudinal Position of Thermal Forcing
Publisher: American Meteorological Society
Abstract: variety of recent studies have shown that extratropical heating anomalies can be remarkably effective at causing meridional shifts in the intertropical convergence zone (ITCZ). But what latitudinal location of forcing is ...
Global warming pattern formation: the role of ocean heat uptake
Publisher: American Meteorological Society
Sensitivity of Polar Amplification to Varying Insolation Conditions
Publisher: American Meteorological Society
Abstract: AbstractThe mechanism of polar amplification in the absence of surface albedo feedback is investigated using an atmospheric model coupled to an aquaplanet slab ocean forced by a CO2 doubling. In particular, we examine the ...
The Response of the ITCZ to Extratropical Thermal Forcing: Idealized Slab-Ocean Experiments with a GCM
Publisher: American Meteorological Society
Abstract: 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 forced from the extratropics. ...
