Abstract:

   Comparative study of El Nino classification after different authors results and approaches. The preferences of objective spatio-temporal classification which done earlier by the authors of present paper were shown for climate manifestation study over the Atlanic-Eurasian region. Using of NCEP/NCAR reanalysis data on sea level pressure in 1948-2016 the El-Nino types manifestations were estimated in Azor high, Iceland low and Siberian anticyclone. On this basis, appropriate prognostic estimates of typical climate anomalies in the Atlantic-Eurasian region are made. Next, the previous predictions of typical climate anomalies in the Atlantic-Eurasian region associated with El Nino types were done in the paper.

Keywords: El-Nino, classification, spatio-temporal features, atmospheric responses, ocean-atmosphere system.
