Machine learning models show varied performance in emulating stratospheric warming events

By PulseAugur Editorial · [2 sources] ·

Researchers have investigated how different machine learning architectures impact the emulation of sudden stratospheric warming (SSW) events. Using idealised Isca simulations, they found that while convolutional, transformer, and graph-based models performed similarly during quiet stratospheric periods, their performance diverged significantly when SSW-like variability was present. The study highlights explicit three-dimensional vertical coupling as a crucial inductive bias for accurately emulating stratospheric dynamics, though it also notes that low forecast error does not always equate to physically accurate wave-mean-flow interactions.
