Functions

i.getoutfn (suffix)
Generator for output file name Adapt this function if you want to have a custom file name (e.g. if you want it to contain certain parameters)

Parameters:

  • suffix Extension, e.g. '.txt' or '.gz'

Returns:

    output name

i
Integration parameters

Fields:

  • t_trans transient period (e.g. 1e7)
  • t_run 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 'writeout' time units
  • statistics accumulate statistics every 'statistics' time units
  • compression compress output of trajectory (if writeout == true)
  • snapshot write out state every 'snapshot' time units (false = no writeout)
  • integrator numerical integration scheme, e.g. "rk2" or "rk4"

Model parameters

Fields:

  • 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
