Logical Model

This provides a reference model of data concepts for service architects and system implementers. It contains the entities necessary to model the shared information of ATM. It can be used in order to construct “derived” logical data models and, indeed, exchange models or physical data models. As such, it can be used to create a model that can be used to build services and operations.

ALTOCUMULUS White or grey, or both white and grey, patch, sheet or layer of cloud, generally with shading, composed of laminae, rounded masses, rolls, etc., which are sometimes partly fibrous or diffuse and which may or may not be merged; most of the regularly arranged small elements usually have an apparent width of between one and five degrees.
ALTOSTRATUS Greyish or bluish cloud sheet or layer of striated, fibrous or uniform appearance, totally or partly covering the sky, and having parts thin enough to reveal the Sun at least vaguely, as through ground glass. Altostratus does not show halo phenomena.
CIRROCUMULUS Thin, white patch, sheet or layer of cloud without shading, composed of very small elements in the form of grains, ripples, etc., merged or separated, and more or less regularly arranged; most of the elements have an apparent width of less than one degree.
CIRROSTRATUS Transparent, whitish cloud veil of fibrous (hair-like) or smooth appearance, totally or partially covering the sky, and generally producing halo phenomena.
CIRRUS Detached clouds in the form of white, delicate filaments or white or mostly white patches or narrow bands. These clouds have a fibrous (hair-like) appearance, or a silky sheen, or both.
CUMULONIMBUS Dense and heavy cloud with a considerable mountain- or tower-shaped vertical extension. These clouds, the base of which is quite dark, may give rise to thunderstorms and generally heavy precipitation in the form of rain, snow, fine or large hail, sometimes accompanied by strong wind gusts.
CUMULUS Detached cloud, generally dense and with sharp outlines, developing vertically in the form of rising mounds, domes or towers, of which the bulging upper part is often like a cauliflower. The sunlit parts are mostly brilliant white and the base is relatively dark and nearly horizontal. Sometimes Cumulus clouds are ragged.
NIMBOSTRATUS Grey cloud layer, often dark, the appearance of which is rendered diffuse by more or less continuously falling rain or snow, which in most cases reaches the ground. It is thick enough throughout to blot out the Sun. Low, ragged clouds frequently occur below the layer, with which they may or may not merge.
STRATOCUMULUS Banks or a layer of grey or whitish clouds generally caught on mountaintops. The base may be fuzzy or smooth and generally horizontal.
STRATUS Generally grey cloud layer with a fairly uniform base, which may give drizzle, ice prisms or snow grains. When the Sun is visible through the cloud, its outline is clearly discernible; Stratus does not produce halo phenomena except, possibly, at very low temperatures; sometimes it appears in the form of ragged patches.
TOWERING_CUMULUS A descriptive term, used mostly in weather observing, for cumulus congestus (Cu con).
