讲座简介:
Weather forecast cares about plausible weather trajectories given incomplete knowledge of current weather status and imperfect forecasting models. Climate prediction cares about climate variability as revealed by a group of imperfect models, under various forcing scenarios. The distinction results from chaotic nature of geophysical fluid dynamics, putting a limit on weather predictability, endorsing climate prediction its in-deterministic nature, and leaving in between a battle field of predictability signal v.s. internal variability noise at subseasonal to seasonal scale.
In this seminar, I will show how we break this long-standing distinction between weather forecast and climate prediction by quantifying the probabilistic distribution of climate state given observational and predictive constraints, using deep generative model. I will also demonstrate the unique advantage of this methodology for data assimilation, seamless forecast, and climate simulation.
