Data Assimilation Models for Computing Probability Distributions of Complex Multiscale Systems
Di Qi, Jian-Guo Liu
We introduce a data assimilation strategy aimed at accurately capturing key non-Gaussian structures in probability distributions using a small ensemble size. A major challenge in s…

Oscillatory solutions at the continuum limit of Lorenz 96 systems
Di Qi, Jian-Guo Liu
In this paper, we study the generation and propagation of oscillatory solutions observed in the widely used Lorenz 96 (L96) systems. First, period-two oscillations between adjacent…
