【 摘 要 】

La Nina manifestations in the meteorological fields of the Atlantic-European region are studied in the paper taking into account its classification based on spatial and temporal features. Monthly global data on sea surface temperature (SST) from COBE SST2 and HadISST data sets in 1900 - 2014, air temperature and sea level pressure from 20th Century Reanalysis V2c were used. Two La Nina types differing one from another in character of SST cold anomaly propagation over the equatorial Pacific region were classified. It is shown that interannual ocean-atmosphere anomalies manifest in the Atlantic-European region mostly in winter due to teleconnection mechanism. Additionally, the role of North Atlantic Oscillation and East Atlantic Oscillation in the level of La Nina types manifestation are analyzed too.
