| Summary: | Despite the large scatter between the various models, the multimodel average sea ice extent is in good agreement with the observations, meaning that there is apparently no systematic bias in the models. On the other hand, the models generally tend to overestimate the variability of the ice extent compared to observations. Over the 20th century, the multimodel average simulates a stronger warming around the peninsula compared to other regions, which is in qualitative agreement with observations. The simulated strength of the ACC varies a lot between the different models, ranging from less than 50Sv to more than 200 Sv. Various factors could explain those large inter-model differences. In particular, the strength of the westerly wind over Report of the second session of the CCl/CLIVAR/JCOMM Expert Team on Climate Change Detection and Indices A. Caltabiano, F. Zweirs and A.
