Is weather chaotic?: Coexistence of chaos and order within a generalized Lorenz model

BW Shen, RA Pielke Sr, X Zeng, JJ Baik… - Bulletin of the …, 2021‏ - journals.ametsoc.org
Over 50 years since Lorenz's 1963 study and a follow-up presentation in 1972, the
statement “weather is chaotic” has been well accepted. Such a view turns our attention from …

Geophysical flows under location uncertainty, Part II Quasi-geostrophy and efficient ensemble spreading
