Webb1 jan. 2012 · 2.3 Probabilistic Forecasts A small ensemble of forecasts provides some scenarios of how the atmosphere may evolve, but it remains necessary to turn this information into a quantitative estimate of the probability that an interesting or dangerous weather event will occur. Webb15 nov. 2024 · MetNet-2’s probabilistic forecasts can be viewed as averaging all possible future weather conditions weighted by how likely they are. Due to its probabilistic nature, MetNet-2 can be likened to physics-based ensemble models, which average some number of future weather conditions predicted by a variety of physics-based models.
