ABSTRACT

The impact of sea surface temperature (SST) anomalies on the extratropical circulation during the El Nino winter of 1997-98 is studied through atmospheric general circulation model (AGCM) integrations. The model's midlatitude response is found to be very robust, of the correct amplitude, and to have a fairly realistic spatial structure. The sensitivity of the results to different aspects of the anomalous distributions of SST is analyzed. It is found that the extratropical circulation in the North Pacific-North American sector is significantly different if SST anomalies over the ...
