Abstract :
[en] In climate simulations, small-scale processes shape ocean dynamics but remain
computationally expensive to resolve directly. For this reason, their
contributions are commonly approximated using empirical parameterizations,
which lead to significant errors in long-term projections. In this work, we
develop parameterizations based on Fourier Neural Operators, showcasing their
accuracy and generalizability in comparison to other approaches. Finally, we
discuss the potential and limitations of neural networks operating in the
frequency domain, paving the way for future investigation.
