Data was collected from aircraft flying through from cumulus clouds off the coast of Key West, Fla., in 2002, and from stratocumulus clouds near Monterey, Calif., in 2003.
If this is so, any cumulus which does form during the daytime will quickly stop growing and spread into a layer of stratocumulus and then disperse when night comes.
In summer, Arctic Ocean packice cover is incomplete and heavily puddled, which maintains a constant layer of stratus and stratocumulus cloud cover.
The stratocumulus cloud breaks up and the sun comes back.
In case of overcast sky, the stratocumulus cloud type is assumed.
They tested their model by comparing its predictions with measurements from field projects devoted to characterizing marine stratocumulus clouds.
Out over the Adriatic the overcast thickened to 10/10 and stratocumulus clouds reared up to 15,000 feet.
It is characterized by a sky covered by a layer of stratus or stratocumulus which tends to persist because of the weak atmospheric circulation.
