| A global coupled General Circulation Model is used to investigate effects of the lateral ocean mixing on the amplitude and spectral characteristics of the ENSO-like variability. Three 40-year coupled simulations are analysed. They only differ by the lateral ocean physics parametrized: a horizontal diffusion scheme; an isopycnal scheme; isopycnal scheme with an Eddy Induced Velocity (EIV) term.The Multichannel Singular Spectrum Analysis is used to extract linear modes of variability from each simulation and from observations. The strength of the variability, close to that observed in the horizontal and only-isopycnal simulations, is stronger in the two isopycnal configurations, and more especially when the EIV is added. The dominant periods of the... |

| VACUMM is an open-source Python library for processing data from observations and numerical models. The library is now used for several years in research and operational contexts, for instance for producing fi gures and reports, validating models, converting data, or making simple or advanced diagnostics. In this paper, we introduce how the library is built, and we present two applications of its use: one in an operational context and one in a research context. |
