Parametrization in an atmospheric model is a method of replacing processes that are too small-scale or complex to be physically represented in the model by a simplified process. This can be contrasted

Stratus clouds are low-level clouds characterized by horizontal layering with a uniform base, as opposed to convective or cumuliform clouds formed by rising thermals. The term stratus describes flat,
Parametrization (atmospheric modeling)
…kilometres (16 mi) can explicitly represent convective clouds, although they still need to parametrize cloud microphysics. The formation of large-scale (stratus-type) clouds is more physically based: they form when the relative humidity reaches some prescribed value. Still, sub grid scale processes need to be…
Typical stratus clouds over Skopje, North Macedonia. The mountains are higher than the cloud top, overlooking a sea of clouds.
