  abstract = {{W}e decompose the monthly global ocean bottom pressure ({OBP}) from {GRACE}(-{FO}) mass concentration solutions, with trends and seasonal harmonics removed from the signal, to extract 23 significant regional modes of variability. {T}he 23 modes are analyzed and discussed considering sea-level anomalies ({SLA}), wind stress curl ({WSC}), and major climate indices. {A} total of two-thirds of the patterns correspond to extratropical regions and are substantially documented in other global or regional studies. {O}ver the equatorial band, the identified modes are unprecedented, with an amplitude ranging between 0.5 and 1 cm. {W}ith smaller amplitude than extratropical patterns, they appear to be less correlated with the local {SLA} or {WSC}; yet they present significantly coherent dynamics. {T}he {P}acific {O}cean modes show significant correlations with the {P}acific decadal oscillation ({PDO}) and {E}l {N}ino southern oscillation ({ENSO}).},
