A '''stratocumulus''' [[cloud]], occasionally called a '''cumulostratus''', belongs to a genus-type of clouds characterized by large dark, rounded masses, usually in groups, lines, or waves, the individual elements being larger than those in [[Altocumulus cloud|altocumulus]], and the whole being at a lower height, usually below {{convert|2000|m|ft}}.<ref name="Stratocumulus">{{cite book |editor=World Meteorological Organization |title=Stratocumulus, International Cloud Atlas |volume=I |year=1975 |url=https://archive.org/details/manualonobservat00worl/page/39 |pages=[https://archive.org/details/manualonobservat00worl/page/39 39–42] |isbn=92-63-10407-7 |access-date=28 November 2014 }}</ref><ref>{{cite web|title= International cloud atlas–Definitions of clouds|publisher= [[World Meteorological Organization]]|url= https://cloudatlas.wmo.int/clouds-definitions.html|access-date= 25 September 2018}}</ref> Weak [[Atmospheric convection|convective]] [[air current|currents]] create shallow cloud layers (see also: [[sea of clouds]]) because of drier, stable air above preventing continued vertical development. Historically, in English, this type of cloud has been referred to as a '''twain cloud''' for being a combination of two types of clouds.
