A Bayesian Deep Learning Approach to Near-Term Climate Prediction

no code implementations23 Feb 2022 Xihaier Luo, Balasubramanya T. Nadiga, Yihui Ren, Ji Hwan Park, Wei Xu, Shinjae Yoo

Since model bias and associated initialization shock are serious shortcomings that reduce prediction skills in state-of-the-art decadal climate prediction efforts, we pursue a complementary machine-learning-based approach to climate prediction.

Predicting Shallow Water Dynamics using Echo-State Networks with Transfer Learning

no code implementations16 Dec 2021 Xiaoqian Chen, Balasubramanya T. Nadiga, Ilya Timofeyev

In this paper we demonstrate that reservoir computing can be used to learn the dynamics of the shallow-water equations.

Feature Importance in a Deep Learning Climate Emulator

no code implementations27 Aug 2021 Wei Xu, Xihaier Luo, Yihui Ren, Ji Hwan Park, Shinjae Yoo, Balasubramanya T. Nadiga

From the perspective of climate dynamics, these findings suggest a dominant role for local processes and a negligible role for remote teleconnections at the spatial and temporal scales we consider.

Leveraging Bayesian Analysis To Improve Accuracy of Approximate Models

no code implementations20 May 2019 Balasubramanya T. Nadiga, Chiyu Jiang, Daniel Livescu

We focus on improving the accuracy of an approximate model of a multiscale dynamical system that uses a set of parameter-dependent terms to account for the effects of unresolved or neglected dynamics on resolved scales.
