Construction of Stable Long-term Climate Emulation

Speaker: Adam Subel, CAOS

Location: Warren Weaver Hall 1314

Date: Friday, October 27, 2023, 4 p.m.

Synopsis:

My talk will look at the construction of stable long-term climate emulation. With the rise of very successful, short-medium range data-driven forecasting, we aim to consider how the emulation problem needs to be reframed in the context of long-term (many year) rollouts. To do this we use the coupled nature of climate models (e.g. atmosphere to ocean) and frame our problem in the context of responding to a boundary forcing. We also explicitly address scale separation both in our data and network design. I will show results for emulating a chunk of the ocean with the atmosphere as a boundary condition, and depending on how tomorrow goes, I will show some preliminary (made that morning) results for a full 1/4 degree ocean.
