Sea ice dissipation based on the method of Rogers et al (2019).

SICE [aice] R19 [c0] [c1] [c2] [c3] [c4] [c5] [c6]

The default options recover the polynomial of Meylan et al. (2014), calibrated for a case of ice floes, mostly 10 to 25 m in diameter, in the marginal ice zone near Antarctica. Examples for other calibrations can be found in the Scientific/Technical documentation.

Fields:

aice (Optional[float])
c0 (float | None)
c1 (float | None)
c2 (float | None)
c3 (float | None)
c4 (float | None)
c5 (float | None)
c6 (float | None)
model_type (Literal['r19', 'R19'])

field aice: float | None = None#

Ice concentration as a fraction from 0 to 1. Note that aice is allowed to vary over the computational region to account for the zonation of ice concentration. In that case use the commands INPGRID AICE and READINP AICE to define and read the sea concentration. The value of aice in this command is then not required (it will be ignored)

Constraints:

ge = 0.0
le = 1.0

field c0: float | None = None#: Polynomial coefficient (in 1/m) for determining the rate of sea ice dissipation (SWAN default: 0.0)

field c1: float | None = None#: Polynomial coefficient (in s/m) for determining the rate of sea ice dissipation (SWAN default: 0.0)

field c2: float | None = None#: Polynomial coefficient (in s2/m) for determining the rate of sea ice dissipation (SWAN default: 1.06E-3)

field c3: float | None = None#: Polynomial coefficient (in s3/m) for determining the rate of sea ice dissipation (SWAN default: 0.0)

field c4: float | None = None#: Polynomial coefficient (in s4/m) for determining the rate of sea ice dissipation (SWAN default: 2.3E-2)

field c5: float | None = None#: Polynomial coefficient (in s5/m) for determining the rate of sea ice dissipation (SWAN default: 0.0)

field c6: float | None = None#: Polynomial coefficient (in s6/m) for determining the rate of sea ice dissipation (SWAN default: 0.0)

field model_type: Literal['r19', 'R19'] = 'r19'#: Model type discriminator

cmd() → str[source]#: Command file string for this component.
