    "abstract": "In this paper we consider the properties of the internal partitions of the\nnonlinear term, obtained when a filter with a sharp cutoff is introduced in\nwavenumber space. We see what appears to be some degree of independence of the\nchoice of the position of the cutoff wavenumber for both instantaneous and\ntime-integrated partitioned nonlinearities. We also investigate the basic idea\nof an eddy-viscosity model for subgrid terms and have found that while phase\nmodelling will be very poor, amplitude modelling can be far more successful.",
