Quasi-Geostrophic Model Simulation

This tutorial walks through running a multi-layer quasi-geostrophic double gyre simulation.

Configuration¶

The MQG simulation is configured via configs/simulation/mqg.yaml:

domain:
  nx: 256
  ny: 256
  dx: 2.0e3
  dy: 2.0e3

physics:
  num_layers: 2
  coriolis_f0: 9.375e-5
  coriolis_beta: 1.754e-11
  bottom_drag: 1.0e-7
  lateral_viscosity: 50.0

Running¶

pixi run simulate-mqg

Expected Behavior¶

The double gyre configuration produces:

• A subtropical gyre (anticyclonic) in the south

• A subpolar gyre (cyclonic) in the north

• A vigorous western boundary current separation

• Mesoscale eddy generation through baroclinic instability
