Abstract: Observational evidence of interhemispheric wave propagation through the equatorial upper-tropospheric mean westerlies in the eastern Pacific Ocean is found in nine years (1980/81 to 1988/89) of European Centre for Medium-Range ...

Abstract: The objective of this study is to investigate the transient evolution of the wintertime atmospheric circulation response to imposed patterns of SST and sea ice extent anomalies in the North Atlantic sector using a large ...

Abstract: he role of ocean?atmosphere coupling in the zonal-mean climate response to projected late twenty-first-century Arctic sea ice loss is investigated using Community Climate System Model version 4 (CCSM4) at 1° spatial ...

Abstract: he impact of projected Arctic sea ice loss on the atmospheric circulation is investigated using the Whole Atmosphere Community Climate Model (WACCM), a model with a well-resolved stratosphere. Two 160-yr simulations are ...

Abstract: Two atmospheric general circulation model experiments are conducted with specified terrestrial snow conditions representative of 1980?99 and 2080?99. The snow states are obtained from twentieth-century and twenty-first-century ...

Abstract: The authors investigate the atmospheric response to projected Arctic sea ice loss at the end of the twenty-first century using an atmospheric general circulation model (GCM) coupled to a land surface model. The response ...

Abstract: resent-day control and 1% yr?1 increasing carbon dioxide runs have been made using two versions of the Community Climate System Model, version 3.5. One uses the standard versions of the ocean and sea ice components where ...

Abstract: rctic sea ice is declining at an increasing rate with potentially important repercussions. To understand better the atmospheric changes that may have occurred in response to Arctic sea ice loss, this study presents results ...

Abstract: ecent work indicates that climate models have a positive bias in the strength of the wintertime low-level temperature inversion over the high-latitude Northern Hemisphere. It has been argued this bias leads to underestimates ...

Abstract: AbstractA traditional view is that the ocean outside of the tropics responds passively to atmosphere forcing, which implies that air?sea heat fluxes are mainly driven by atmosphere variability. This paper tests this viewpoint ...
