Did an El Nino event occurred during the winter of 2015-2016?
El Niño 2015-16 was in the same grouping as the greatest occurrences of the twentieth century. ECMWF (European Centre for Medium-Range Weather Forecasts) and multi-model EUROSIP predictions have well-projected its evolution. El Niño, the warm stage of the Southern Oscillation of El Niño (ENSO), and the cold stage is called La Niña. The cool stage. The two strongest "El Niños" occurred between 1982/83 and 1997/98, which were each considered "once in a hundred years" cases at that time.
The 2015/16 El Niño is from the same category as that of 1982/83, 1997/98 and then it sets new benchmarks in the Central and Western Pacific regions of NINO4 and NINO3.4. The El Niño spatial framework at its maximum point in November 2015 is shown in figure 1. The massive magnitude and the potential to affect the "deep tropical convection" that powers the total flow of the climate is just what brings El Niño its significant global impact. The zonal (East-West) scale is over 10,000 km. The variability of El Niño is typically tracked through the use of indexes dependent on average sea-surface temperature (SST) over map regions.
