Departures are based on a set of improved homogeneous historical SST analyses (Extended Reconstructed SST \u2013 ERSST.v4). The SST reconstruction methodology is described in Huang et al., 2015, J.

By historical standards, to be classified as a full-fledged El Ni\u00f1o or La Ni\u00f1a episode, these thresholds must be exceeded for a period of at least 5 consecutive overlapping 3-month seasons.<\/h3>\n<h3>CPC considers El Ni\u00f1o or La Ni\u00f1a conditions to occur when the monthly Ni\u00f1o3.4 OISST departures meet or exceed +\/- 0.5\u00baC along with consistent atmospheric features.
