  • LRECYCL : Flag to activate turbulence recycling method or not.

    • .TRUE. : turbulence recycling method is activated.

    • .FALSE. : turbulence recycling method is not activated.

Warning

In its current version, the turbulence recycling method has only been validated with flat terrain (LFLAT=.TRUE.), cartesian coordinates (LCARTESIAN=.TRUE.), and a near-neutral boundary layer.

  • LRECYCLW,E,S,N : Flag to activate turbulence recycling method on the West, East, South, North boundaries of the domain or not.

    • .TRUE.: turbulence recycling method is activated on the West, East, South, North boundaries of the domain.

    • .FALSE.: turbulence recycling method is not activated on the West, East, South, North boundaries of the domain.

  • XDRECYCLW,E,S,N : Distance (in meters) of the recycling plan to the West, East, South, North boundary (1/4 of the domain is recommended).

  • XARECYCLW,E,S,N : Angle between the recycling plan and the West, East, South, North boundary (0. for X-direction and \(\frac{\pi}{2}\) for Y-direction).

  • NTMOY : Total number of time-steps within time window for the calculation of the moving temporal average.

  • NNUMBELT : Number of elements used for the variable averaging.

  • NTMOYCOUNT : Number of time-steps between an update of the averaged variable (NTMOYCOUNT=NTMOY/NNUMBELT)

  • XRCOEFF : Weighting coefficient for the turbulent fluctuations, preventing calculation divergence. XRCOEFF in [0.1-0.3] for near-neutral simulations.

  • XTBVTOP : Threshold to filter the gravity waves. Shoud be equal to approximatively 4 times the Brunt-Vaisala period.

  • XTBVBOT : Threshold to filter the gravity waves. Shoud be equal to approximatively 2 times the Brunt-Vaisala period.
