Common questions¶
How to calculate LAM resolution?¶
Take LAM radius and divide it by the nbp icosahedral division factor. For example, this Antartica configuation:
corresponds to a 105 km grid size (radius [km] / nbp = 3360 [km] / 32 = 105 [km])
How to select dissipation parameters?¶
These three parameters should be adjusted in accordance to the LAM resolution. Selecting them is a matter of trail and error, so that's why you can use proposed values:
| resolution [km] | tau_graddiv | tau_gradrot | tau_divgrad |
|---|---|---|---|
