Effective grid size

[levi_ackerman0929]

What is the effective grid size of microphysics and cumulus schemes like the minimum grid size where we can see the effect of these schemes?

Hi,
For cumulus scheme, the grid six should be larger than 10km. The interval between 4-10 is regarded as a grey zone and there is consensus whether a cumulus scheme should be turned on or off. Grid interval below 3km is the traditional cloud-resolving resolution and no cumulus scheme is required.

Microphysics is always on no matter what grid size you choose.
