ECMWF-S4 ensemble mean temporal correlation of el Niño and NAO indices against ERA-Interim

These images show maps of temporal correlation coefficients between ECMWF-S4 raw and ERA-Interim teleconnection indices (NAO and NINO3.4). The images cover the period 1981-2015 and are organised according to the four seasons with 0, 1, 2, 3 and 4 months lead. For more information, see Scientific Technical Note Marcos et al. (2016a).
