| Summary: | The interaction between the atmosphere and ocean was investigated in the middle latitudes under winter conditions. To this end, a series of numerical experiments were carried out with the INM RAS atmospheric general circulation model in the regime of perpetual January for 360 months of model time. In one of experiments, a model of oceanic upper layer for the midlatitude Northern Hemisphere was joint to the model of atmosphere. Two experiments were performed with constant positive and alternating in sign (with a denite temporal structure) SST anomaly in the North Atlantic. Spatial monopole structure of SST anomaly and its time cycle were chosen to be correlated with the dynamics of atmospheric model according to the results of experiment with the coupled model. It was shown that a localized response of the atmosphere model to SST anomaly has a baroclinic structure and is easily extracted as a response to nonstationary SST anomaly. Spatial structure of this response to th. |
