i
Integration parameters

Fields:

  • ntrans transient period (e.g. 1e7)
  • niter length of trajectory on the attractor (e.g. 5e8)
  • dt the time step
  • out_prefix prefix for the output file name
  • writeout write out all variables every 10 time units
m
Model parameters

Fields:

  • scale the characteristic space scale, L*pi
  • f0 Coriolis parameter at 45 degrees latitude
  • n aspect ratio (n = 2Ly/Lx ; Lx = 2piL/n; Ly = pi*L)
  • rra earth radius
  • phi0 latitude Parameters for the ocean
  • gp reduced gravity
  • r frictional coefficient at the bottom of the ocean
  • H depth of the water layer
  • alpha coefficient characterizing the intensification of the flow on the western boundaries
  • d the coupling parameter (should be divided by f0 in order to be adimensional) Parameters for the atmosphere
  • k bottom friction coefficient
  • kp internal friction coefficient
  • hpp coefficient associated with the thermal relaxation time scale (Newtonian heating)
  • sig0 static stability
  • thetastar Newtonian heating parameter; a value of 0.14 should produce chaos.
