But when climate changes even by what appear, to us, to be very small amounts, that can have huge effects on how weather systems behave.
Thus, if you want your AI model that predicts weather, which was trained on data before that change, to predict weather after that change, you may very well find that it rapidly loses accuracy.
- jvanderbot 2y agoI think the naive answer is that physics doesn't change when the climate does, just the initial conditions for the day's simulation of the next week's weather. And every year over year change is within error bars of the prior years results, once you account for those initial conditions.
- danaris 2y agoAnd if your model is based on physics, then that's fine. But if your model is an LLM (or close cousin) purely based on previous weather patterns, then it may struggle to accurately predict once the underlying conditions change.
- geysersam 2y agoThe less naive answer is that a typical weather model has hundreds of parameters that have been tuned manually over decades of use.
