  abstract = {{A}ndean tropical glaciers have shown a clear shrinkage throughout the last few decades. {H}owever, it is unclear how this general retreat is associated with variations in rainfall patterns in the {A}mazon basin. {T}o investigate this question, we compared the annual net accumulation variations in the {B}olivian {C}ordillera {R}eal ({A}ndes), which is derived from an ice core from the {N}evado {I}llimani (16{A} degrees 37' {S}, 67{A} degrees 46' {W}), covering the period 1960-1999 using the {A}mazonian {R}ainfall {I}ndex, {N}orthern {A}tlantic {I}ndex ({TNA}), {M}ultivariate {ENSO} {I}ndex ({MEI}), and {P}acific {D}ecadal {O}scillation ({PDO}). {T}he accumulation rate at the {N}evado {I}llimani ice core decreased by almost 25% after 1980, from 1.02 w.eq. a(-1) (water equivalent per year) in the 1961-1981 period to 0.76 w.eq. a(-1) in the 1981-1999 period. {T}he {N}orthern {A}mazonian {R}ainfall ({NAR}) index best reflects changes in accumulation rates in the {B}olivian ice core. {O}ur proposal is based on two observations: (1) {T}his area shows reduced rainfall associated with a more frequent and intense {E}l {N}io (during the positive phase of the {MEI}). {T}he opposite (more rain) is true during {L}a {N}ia phases. (2) {C}omparisons of the ice core record and {NAR}, {PDO}, and {MEI} indexes showed similar trends for the early 1980s, represented by a decrease in the accumulation rates and its standard deviations, probably indicating the same causality. {T}he general changes observed by early 1980s coincided with the beginning of a {PDO} warm phase. {T}his was followed by an increase in the {A}mazonian and tropical {A}ndean precipitation from 1999, coinciding with a new {PDO} phase. {H}owever, this increase did not result in an expansion of the {Z}ongo {G}lacier area.},
