ECHAM6 T255L199 amip_r1i1p31 experiment description¶

The amip_r1i1p31 experiment starts 1976. Following parameter settings were used:

• Cloud parameters:
  • cmfctop = 0.23
  • cprcon = 0.6e-4
  • zinhoml1 = zinhoml2 = 0.77

• Horizontal diffusion:
  • dampth = 0.5
  • ihq(1:13) = 1
    ihq(14:199) = 2
  • dift = 0.8 * difvo
  • above 70 hPa additional damping for the last seven waves (n = 249,250,...,255)

• Orographic gravity wave drag parameters (Lott, 1999)
  • gkdrag = 0.2
  • gkwake = 0.2

• Hines gravity wave parametrization
  • emiss_lev = 26
  • lrmscon_lat = .false.
