Circulation Anomalies in the Atmospheric Centers of Action during the Eastern Pacific and Central Pacific El Nino

I. V. Zheleznova and D. Yu. Gushchina

Based on the statistical analysis the teleconnections between circulation anomalies in the at- mospheric centers of action and sea surface temperature anomalies are revealed for two types of El Nio. It is demonstrated that for the Eastern Pacific El Nio stronger teleconnections are registered in the North- ern Hemisphere whereas the response to the Central Pacific El Nio is much stronger in the Southern Hemisphere. The Central Pacific El Nio is characterized by the more rapid signal propagation from the tropical zone to distant regions. In some cases the pattern of interaction with the atmospheric circulation considerably differs for two types of El Nio that defines differences in the fields of weather anomalies.
