Abstract:

   The features of La Nina 2016 were studied taking into account the spatial classification of the cold episodes of El Nino – Southern Oscillation. Using sea surface temperature (SST) data sets of COBE SST in 1900 –2014 two La Nina types were separated. They differ one from another by the character of cold SST anomalies propagation in the equatorial Pacific. The pattern of development and intensity of La Nina 2016 was analyzed and defined on the basis of SST anomalies in Nino3.4 and Nino1+2 regions, surface currents and Southern Oscillation index.

Keywords: La Nina, sea surface temperature, the Pacific Ocean, surface currents, Southern Oscillation, El Nino.
