1803 L. Howard On Modification of Clouds 5 Stratus... A widely extended, continuous, horizontal sheet, increasing from below upward. This application of the Latin word stratus is a little forced. But the substantive, stratum, did not agree in its termination with the other two [i.e. cirrus, cumulus], and is besides already used in a different sense even on this subject, e.g. a stratum of clouds; yet it was desirable to keep the derivation from the verb sterno, as its significations agree so well with the circumstances of this cloud.

1832 D. Brewster Lett. Nat. Magic vi. 140 A thin stratus or ‘fog bank’ appeared in the same quarter.

1882 D. Pidgeon Engineer's Holiday II. 216 Extending..a considerable distance towards the zenith, lay a thick horizontal layer of stratus, above which was blue.

1934 A. H. R. Goldie Abercromby's Weather (rev. ed.) iv. 74 If a layer of stratus is thin it gives the sky a misty appearance and some drizzle may occasionally fall from it.

1985 M. Parfit South Light (1988) xx. 250 Layers of stratus gave the sharp rocks mystery.
