| Summary: | ol run in which the mean seasonal SST cycle of the 700 year ECHAM3/LSG integration is prescribed 6 . It is found that the atmospheric circulation response to negative midlatitudinal SSTA (not shown) is characterized by a weakened subtropical jet, negative 6 A more thorough analysis of these experiments is presented in a forthcoming paper by Merkel, Timmermann and Latif. 43 4.5. DISCUSSION AND SUMMARY 44 NAO and positive PNA indices, and hence the reversed Arctic Oscillation. These findings reveal that not only the atmosphere forces the ocean as discussed in the previous section but that also the resulting SST anomalies change the atmospheric dynamics in such a way that enables a positive atmosphere-ocean feedback. 4.5 Discussion and Summary It has long been recognized (Hakkinen 1993, Yang and Neelin 1993) that sea-ice dynamics can become an important contributor to decadal and interdecadal climate variabilit |
