ADAF: An Artificial Intelligence Data Assimilation Framework for Weather Forecasting

Journal of Advances in Modeling Earth Systems
The forecasting skill of numerical weather prediction (NWP) models critically depends on the accurate initial conditions, also known as analysis, provided by data assimilation (DA). Traditional DA methods often face a trade‐off between computational cost

Tropical symmetries of cluster algebras

We study tropicalisations of quasi-automorphisms of cluster algebras and show that their induced action on the g-vectors can be realized by tropicalising their action on the homogeneous $\hat{y}$ (or $\mathcal{X}$) variables of a chosen initial cluster.

Algebraic Aspects in Tropical Mathematics

, 2013
Much like in the theory of algebraic geometry, we develop a correspondence between certain types of algebraic and geometric objects. The basic algebraic environment we work in is the a semifield of fractions H(x1,...,xn) of the polynomial semidomain H[x1,...,xn], where H is taken to be an idempotent semifield, while for the geometric environment we ...
