In this [work](https://doi.org/10.48550/arXiv.2602.13847), **Fabrizio Falasca** and **Laure Zanna** introduce a **flexible framework that combines response theory and score matching to eliminate spurious, noncausal dependencies in reduced-order neural emulators of turbulent systems.** Using the stochastic **Charney–DeVore model** as a proof of concept for low-frequency atmospheric variability, they demonstrate that **enforcing causal constraints significantly improves emulator responses** to both weak and strong external forcings, even when trained solely on unforced data. The framework is broadly applicable to complex turbulent systems and can be seamlessly integrated into standard neural network architectures, offering a principled **path toward more reliable climate emulators**.

Mesoscale eddies are the ocean’s primary reservoir of kinetic energy, yet most climate models cannot fully resolve them due to computational limits. In this [study](https://doi.org/10.22541/essoar.177100611.18240844/v1) led by **David Kamm**, two **machine-learning–based eddy parameterizations**, Zanna and Bolton (2020) parameterization (ZB20) and Guillaumin and Zanna (2021) parameterization (GZ21), are **implemented in the NEMO ocean model and evaluated against high-resolution simulations.** While GZ21 shows systematic biases linked to grid spacing and does not improve coarse-resolution performance, **ZB20 successfully captures subgrid energy transfers, leading to improved kinetic energy spectra and large-scale circulation.** The results highlight that carefully designed, resolution-aware training data are essential for developing robust and generalizable data-driven eddy parameterizations.
