Abstract

We built NaiNUQ, a multivariate deterministic emulator of the sea-ice model NANUQ which can handle seasonal prediction. Forcing a sea-ice neural emulator with ocean surface currents causes instabilities in the prediction. Using ocean sub-surface currents removes this instability, yielding stable emulator that outperforms atmosphere-only emulators.
