Preprint is out!
We use ML (equation discovery) to get equations for vertical diffusivity in the ocean surface boundary layer.
Equations also reveal & fix a structural error in the baseline physics based scheme! 😃

Our educational notebook has been published in the Journal of Open Source Education! We introduce climate modeling using a simple & computationally cheap framework- the Lorenz 96 model. The L96 model captures the essence of sub-grid parameterizations and data-assimilation used in climate models. 1/3

Data-Driven Science: Developments in Machine Learning Subgrid-Scale Parameterizations and in Reanalyses Across Earth System Modeling I Oral
Subgrid-scale (SGS) parameterizations estimate effects of unresolved processes without modeling them directly and are often a large source of uncertainty in Earth system models (ESMs). The need to imp...

We have a new paper on how increasing atm. CO₂ & warming global temperatures will "prime" the tropical Pacific #Ocean for more *frequent* extreme El Niño events! Our simulation is validated using Ice Age data when El Niño variability was weaker than today.

Resharing this for the Oceanography feed 🌊
In this manuscript, we show how to use metrics from information theory to estimate relative contribution between intrinsic vs extrinsic variability in ensemble models. These metrics can be applied even when data is non-Gaussian.
