Report

Efficient fine-tuning of 37-level GraphCast with the Canadian global deterministic analysis

Autor: Subich, Christopher

This work describes a process for efficiently fine-tuning the GraphCast data-driven forecast model to simulate another analysis system, here the Global Deterministic Prediction System (GDPS) of Environment and Climate Change Canada (ECCC). Using two

Autor: Husain, Syed Zahid, Separovic, Leo, Caron, Jean-François, Aider, Rabah, Buehner, Mark, Chamberland, Stéphane, Lapalme, Ervig, McTaggart-Cowan, Ron, Subich, Christopher, Vaillancourt, Paul A., Yang, Jing, Zadra, Ayrton

Operational meteorological forecasting has long relied on physics-based numerical weather prediction (NWP) models. Recently, this landscape is facing disruption by the advent of data-driven artificial intelligence (AI)-based weather models, which off

Simulation of the Navier-Stokes Equations in Three Dimensions with a Spectral Collocation Method

Autor: Subich, Christopher

This work develops a nonlinear, three-dimensional spectral collocation method for the simulation of the incompressible Navier-Stokes equations for geophysical and environmental flows. These flows are often driven by the interaction of stratified flui
