Reply to Comment on ‘Linkage of El Nino-Southern Oscillation to astronomic forcing’

Abstract Ray and Wunsch (2025) have provided a Comment to Valle-Levinson (2024) and Valle-Levinson and Pattiaratchi (2024) that identify two points of contention: lack of statistical evidence and lack of physical evidence between ENSO and astronomic cycles. We argue that we tried to determine whether a random noise signal could be reproduced with the astronomic harmonics that we used to reconstruct climate and water level signal. This is different from trying to represent a signal with white noise. Moreover we have followed previous findings that the lunar nodal cycle can modulate vertical mixing in the ocean, as well as surface temperature, salinity, air-sea heat fluxes, atmospheric pressures and steric sea levels.
