Extracting transient Koopman modes from short-term weather simulations with sparsity-promoting dynamic mode decomposition
Zhicheng Zhang, Yoshihiko Susuki, Atsushi Okazaki
Convective features, represented here as warm bubble-like patterns, reveal essential high-level information about how short-term weather dynamics evolve within a high-dimensional s…

Sparsity-Promoting Dynamic Mode Decomposition Applied to Sea Surface Temperature Fields
Zhicheng Zhang, Yoshihiko Susuki, Atsushi Okazaki
In this paper, we leverage Koopman mode decomposition to analyze the nonlinear and high-dimensional climate systems acting on the observed data space. The dynamics of atmospheric s…
