  abstract = {{I}n 2023 {A}mazonia experienced both historical drought and warm conditions. {O}n {O}ctober 26th 2023 the water levels at the port of {M}anaus reached its lowest record since 1902 (12.70 m). {I}n this region, {O}ctober monthly maximum and minimum temperature anomalies also surpassed previous record values registered in 2015 (+ 3 °{C} above the normal considering the 1981-2020 average). {H}ere we show that this historical dry and warm situation in {A}mazonia is associated with two main atmospheric mechanisms: (i) the {N}ovember 2022-{F}ebruary 2023 southern anomaly of vertical integrated moisture flux ({VIMF}), related to {VIMF} divergence and extreme rainfall deficit over southwestern {A}mazonia, and (ii) the {J}une-{A}ugust 2023 downward motion over northern {A}mazonia related to extreme rainfall deficit and warm conditions over this region. {A}nomalies of both atmospheric mechanisms reached record values during this event. {T}he first mechanism is significantly correlated to negative sea surface temperature ({SST}) anomalies in the equatorial {P}acific ({N}ovember-{F}ebruary {L}a {N}iña events). {T}he second mechanism is significantly correlated to positive {SST} anomalies in the equatorial {P}acific, related to the impacts of {J}une-{S}eptember {E}l {N}iño on the {W}alker {C}irculation. {W}hile previous extreme droughts were linked to {E}l {N}iño (warmer {N}orth {T}ropical {A}tlantic {SST}) during the austral summer (winter and spring), the transition from {L}a {N}iña 2022-23 to {E}l {N}iño 2023 appears to be a key climatic driver in this record-breaking dry and warm situation, combined to a widespread anomalous warming over the worldwide ocean.},
