The atmospheric response to North Atlantic sea surface temperature anomalies in GCM experiments

The main goal of this GCM experiments with constant SST anomalies was to determine the dynamical mechanisms which are relevant for the development of the extratropical atmospheric response to SST anomalies in the midlatitudes of the North Atlantic. The linearity and the dependence of the atmospheric response on the geographical localization of SST anomalies was also examined. The GCM experiments with SST anomalies in different geographical regions indicate that the atmospheric reaction is very sensitive to the position of the SST anomaly. Especially strong atmospheric response in this particular GCM was found only in the case of the positive SST anomalies placed of the US coast. The response to SST anomalies east of Newfoundland was significantly weaker. The atmospheric response in the GCM experiments with prescribed SST anomalies occur, at best simultaneously with SST variations or lag them. Thus, they demonstrate possible feedbacks from the SST on the atmospheric circulation.
