(2014), we add an observed {WWB} to simulations within a comprehensive coupled model and explore changes in the available potential energy ({APE}) of the tropical {P}acific basin. {W}e find that {WWB} impacts strongly depend on the ocean initial state and can range from a {C}entral {P}acific ({CP}) to {E}astern {P}acific ({EP}) warming, which is closely reflected by the ocean energetics. {C}onsequently, the {APE} can be used to quantify the diversity of {E}l {N}ino events within this continuum-higher negative {APE} values typically correspond to {EP} events, lower values to {CP} events. {W}e also find that a superimposed {WWB} enhances {E}l {N}ino predictability even before the spring predictability barrier, if one uses the {APE} as a predictor.}, keywords = {{PACIFIQUE} ; {ZONE} {TROPICALE}}, booktitle = {}, journal = {{G}eophysical {R}esearch {L}etters}, volume = {41}, numero = {13}, pages = {4654--4663}, ISSN = {0094-8276}, year = {2014}, DOI = {10.1002/2014gl059573}, URL = {https://www.documentation.ird.fr/hor/fdi:010062443}, }
