Using Probabilistic Machine Learning to Better Model Temporal Patterns in Parameterizations: a case study with the Lorenz 96 model

1 code implementation • 28 Mar 2022 • Raghul Parthipan, Hannah M. Christensen, J. Scott Hosking, Damon J. Wischik

The modelling of small-scale processes is a major source of error in climate models, hindering the accuracy of low-cost models which must approximate such processes through parameterization.
