The cloud base (or the base of the cloud) is the lowest altitude of the visible portion of the cloud. It is traditionally expressed either in m or feet above mean sea level (or planetary surface), or as the corresponding pressure level in hectopascal (hPa, equivalent to millibar).

Famous quotes containing the words cloud and/or base:
“When I from black and he from white cloud free,
And round the tent of Godlike lambs we joy,
I’ll shade him from the heat till he can bear
To lean in joy upon our father’s knee;
And then I’ll stand and stroke his silver hair,
And be like him, and he will then love me.”
—William Blake (1757–1827)
“I think it is worse to be poor in mind than in purse, to be stunted and belittled in soul, made a coward, made a liar, made mean and slavish, accustomed to fawn and prevaricate, and “manage” by base arts a husband or a father,—I think this is worse than to be kicked with hobnailed shoes.”
—Frances Power Cobbe (1822–1904)
