Here, we generate three different datasets (true state, noisy observations and analog database) using the ex- act Lorenz-63 differential equations with the classical parameters ρ =

Strongly coupled EnKF was implemented in [61] to recover the Atlantic merid- ional overturning circulation (AMOC) with simulated observations in a low-order coupled

We show how various non-dissipative transfer schemes can be used to transfer and store quantum states such as squeezed vacuum states or entangled states into the long-lived ground

With the input wave spectrum from WW3, the Boussinesq-type wave model, BOSZ, not only captures the main hydrodynamic processes such as refraction, shoaling,
