Stratus silvagenitus is a type of stratus cloud. The word is a scientific Latin coinage meaning "created from forest".[1] This cloud type forms over forested areas which are experiencing high relative humidity levels, for example, after precipitation has passed, through evaporation and/or evapotranspiration.[2]
If the cloud is uniform, it is called a "stratus" silvagenitus cloud, if the cloud is ragged and wispy, then it is called a "stratus fractus" silvagenitus cloud. These clouds typically form near the ground. The silvagenitus cloud variety only appears in the Stratus cloud species due to its mechanism of formation, as it is driven by forced increase of dew point instead of convective adiabatic cooling like in cumulus clouds.
