étage in a sentence

The stratiform group is cross-classified into the genera cirrostratus (high-étage), altostratus (middle-étage), stratus (low-étage), and nimbostratus (multi-étage).

The stratocumuliform group is cross-classified into the genera cirrocumulus (high-étage), altocumulus (middle-étage), and stratocumulus (low-étage).

Alternatively, some classifications do not recognize a vertical or multi-étage designation for any genus types and include all vertical free-convective cumuliform and cumulonimbiform genera with the low-étage clouds.

With this method of nomenclature, a cloud genus can be defined as any physical form that is particular to a given étage, or simultaneously to more than one étage if the genus-type has significant vertical extent.

Ariane 5 ECA uses the ESC (Étage Supérieur Cryotechnique—Cryogenic Upper Stage), which is fueled by liquid hydrogen and liquid oxygen.

Classifications that follow this approach usually show nimbostratus either as low-étage citation to denote its normal base height range, or as middle, based on the altitude range at which it normally forms.

Contrails formed from the exhaust of aircraft flying in the high étage can persist and spread into formations resembling any of the high cloud genus-types.

Despite this hierarchy, a particular species may be a subtype of more than one genus, especially if the genera are of the same physical form and are differentiated from each other mainly by altitude or étage.

Genus types in this étage either have no prefix or carry one that refers to a characteristic other than altitude.

In the intermediate range, from convert to convert in temperate regions, are the mid-étage clouds.

Low- and multi-étage genera of any form do not have altitude-related prefixes.

Low stratocumuliform, stratiform, and cumuliform genera Low-étage clouds are found from near surface up to convert.

One group identifies the opacities of particular low and middle étage cloud structures and comprises the varieties translucidus (thin translucent), perlucidus (thick opaque with translucent breaks), and opacus (thick opaque).

Polar mesospheric clouds Noctilucent cloud over Estonia main Polar mesospheric clouds form at a single extreme altitude range of about convert and are consequently not classified into more than one étage.

Smaller low-étage "pyrocumulus" or "fumulus" clouds formed by contained industrial activity could be classified as cumulus homogenitus.

Stratocumuliform and stratiform clouds in the high étage carry the prefix cirro-, yielding the respective genus names cirrocumulus (Cc) and cirrostratus (Cs).

Stratocumuliform and stratiform genera have the prefix cirro- when they occur in the high étage, and alto- when based in the middle altitude range.

Stratus clouds are also low-étage.

Summary of étages and genera seeAlso The forms and resultant genus types can be grouped by étage.

The forms are cross-classified by étage to produce ten basic genus-types or genera.
