  abstract = {{W}hile, climatologically, most areas of the {P}eruvian {P}acific region do not experience precipitation, they can be affected by heavy rain and flooding during strong {E}l {N}ino events with severe socio-economic impacts. {O}nly four strong {E}l {N}ino events took place within the last five decades (1972/1973, 1982/1983, 1997/1998 and 2015/2016) which led to significant rainfall events in the northern part of {P}eru. {H}ere a detailed analysis of the evolution of precipitation during these events was performed using gauge records from 1964 to 2016 from a network of 145 meteorological stations located along the {P}eruvian {P}acific region. {T}hrough empirical orthogonal function analysis, the rainfall anomalies variability is interpreted as resulting from the combination of a meridional see-saw mode ({N}orth-{S}outh) ({E}p mode) and a zonal see-saw mode ({E}ast-{W}est) ({C}p mode) that represent, respectively, 34 and 21% of the explained variance. {I}t is shown that the extreme 1982/1983 and 1997/1998 {E}l {N}ino events have a dominant projection on the {E}p mode that has a strong loading in the northern region, while the 1972/1973 and 2015/2016 {E}l {N}ino events have a relatively weak projection onto the {E}p mode (about ten times less at the peak rainy season than the extreme events) and mostly project onto the {C}p mode. {A}lso, it is shown that while all events are associated with positive rainfall anomalies in the northern part of {P}eru which is accounted for by the {E}p mode, the evolution of rainfall anomalies along the {C}p mode exhibits a significant dispersion. {T}his suggests that the impact of strong {E}l {N}ino events on the highlands along the coast cannot solely be inferred from the magnitude of the sea surface temperature anomalies in the central equatorial {P}acific. {O}verall, our study illustrates the nonlinearity of the {ENSO} teleconnection on the rainfall along the coast of {P}eru during strong {E}l {N}ino events.},
