Aakash Sane @aakashsane.bsky.social · 26/12/2024Our 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. 1/3 131
