This study uses a hybrid coupled model (referred to as the general‐circulation model (GCM)/Zebiak/Cane (ZC) model), which consists of the Goddard Institute for Space Studies' (GISS) Atmospheric general‐circulation model (AGCM) coupled to the oceanic component of the ZC intermediate model to assess the impact of global warming on El Niño behavior, with and without the influence of heat introduced from the subtropical Pacific (v...

This study re‐evaluated simulated Antarctic sea‐ice variability and its teleconnections in a NASA Goddard Institute for Space Studies (GISS) coupled global climate model (CGCM) with improved sea‐ice and ocean processes. With the improvements to the parameterizations of sea‐ice dynamics and thermodynamics and of sub‐grid‐scale ocean processes, the new version of the GISS/CGCM does indeed do a better job in the representations o...

This study evaluates simulated Antarctic sea ice edge (SIE) variability and its teleconnections in three global coupled climate models (GISS, NCAR and GFDL) against the observations. All models do a reasonable job in simulating the seasonal advance and retreat of the Antarctic sea ice fields. The simulated GISS and NCAR SIE distributions are in agreement with observations in summer and autumn, whereas the GFDL model does best...
