  abstract = {{R}ecent studies have highlighted the role of subsurface ocean dynamics in modulating eastern {P}acific ({EP}ac) hurricane activity on interannual time scales. {I}n particular, the well-known {E}l {N}ino-{S}outhern {O}scillation ({ENSO}) recharge-discharge mechanism has been suggested to provide a good understanding of the year-to-year variability of hurricane activity in this region. {T}his paper investigates the influence of equatorial subsurface subannual and intraseasonal oceanic variability on tropical cyclone ({TC}) activity in the {EP}ac. {T}hat is to say, it examines previously unexplored time scales, shorter than interannual, in an attempt to explain the variability not related to {ENSO}. {U}sing ocean reanalysis products and {TC} best-track archive, the role of subannual and intraseasonal equatorial {K}elvin waves ({EKW}) in modulating hurricane intensity in the {EP}ac is examined. {I}t is shown first that these planetary waves have a clear control on the subannual and intraseasonal variability of thermocline depth in the {EP}ac cyclone-active region. {T}his is found to affect ocean subsurface temperature, which in turn fuels hurricane intensification with a marked seasonal-phase locking. {T}his mechanism of {TC} fueling, which explains up to 30% of the variability of {TC} activity unrelated to {ENSO} (around 15%-20% of the total variability), is embedded in the large-scale equatorial dynamics and therefore offers some predictability with lead time up to 3-4 months at seasonal and subseasonal time scales.},
