1. A collection of visible vapor, or watery particles, suspended in the upper atmosphere.
I do set my bow in the cloud.
Gen. ix. 13.
A classification of clouds according to their chief forms was first proposed by the meteorologist Howard,
and this is still substantially employed. The following varieties and subvarieties are recognized: (a) Cirrus.
This is the most elevated of all the forms of clouds; is thin, long-drawn, sometimes looking like carded
wool or hair, sometimes like a brush or room, sometimes in curl-like or fleecelike patches. It is the cat's-
tail of the sailor, and the mare's-tail of the landsman. (b) Cumulus. This form appears in large masses
of a hemispherical form, or nearly so, above, but flat below, one often piled above another, forming great
clouds, common in the summer, and presenting the appearance of gigantic mountains crowned with
snow. It often affords rain and thunder gusts. (c) Stratus. This form appears in layers or bands extending
horizontally. (d) Nimbus. This form is characterized by its uniform gray tint and ragged edges; it covers
the sky in seasons of continued rain, as in easterly storms, and is the proper rain cloud. The name is
sometimes used to denote a raining cumulus, or cumulostratus. (e) Cirro-cumulus. This form consists,
like the cirrus, of thin, broken, fleecelice clouds, but the parts are more or less rounded and regulary
grouped. It is popularly called mackerel sky. (f) Cirro-stratus. In this form the patches of cirrus coalesce
in long strata, between cirrus and stratus. (g) Cumulo-stratus. A form between cumulus and stratus,
often assuming at the horizon a black or bluish tint. — Fog, cloud, motionless, or nearly so, lying near
or in contact with the earth's surface. — Storm scud, cloud lying quite low, without form, and driven
rapidly with the wind.
2. A mass or volume of smoke, or flying dust, resembling vapor. "A thick cloud of incense." Ezek. viii.
11.
3. A dark vein or spot on a lighter material, as in marble; hence, a blemish or defect; as, a cloud upon
one's reputation; a cloud on a title.
4. That which has a dark, lowering, or threatening aspect; that which temporarily overshadows, obscures,
or depresses; as, a cloud of sorrow; a cloud of war; a cloud upon the intellect.
