Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
DEF

Photometeor consisting of a luminous arc of a circle situated in a horizontal plane and centred at the zenith.

OBS

It sometimes happens that circumzenithal arcs are seen when the large halo is not visible.

OBS

It is produced by the refraction of light through the 90° prisms of ice crystals, having entered through the horizontal bases and passed out through the vertical sides. Normally, the crystals are large, oriented, hexagonal plates. The circumzenithal arc is the high sky counterpart of the circumhorizontal arc. The circumhorizontal arc is low in the sky when the sun is high (above 58° elevation); the circumzenithal arc is high in the sky when the sun is low (below 32° elevation). The majority of circumzenithal arcs are short-lived, short in length and faint or moderately bright. However, very colorful circumhorizontal arcs can occur when the refraction is close to the minimum angle of deviation, corresponding to a solar elevation angle of about 22°.

French

Domaine(s)
  • Phénomènes météorologiques, climatiques et atmosphériques
DEF

Photométéore consistant en un arc de cercle lumineux situé dans un plan horizontal et centré au zénith.

CONT

L'arc circumzénithal est moins fréquent, car il n'apparaît que si la hauteur du soleil au-dessus de l'horizon est inférieure à 32,2 degrés. Cet arc est formé quand la lumière solaire entre dans le cristal par la face horizontale supérieure et en ressort par une face latérale verticale. Quand le soleil est au-dessus de 32,2 degrés, la lumière est entièrement réfléchie à l'intérieur du cristal; c'est pourquoi on ne voit cet arc que lorsque le Soleil est relativement bas sur l'horizon. À 32,2 degrés, la lumière ressort du cristal verticalement vers le bas; on verra alors l'arc circumzénithal comme un point éclatant au zénith. À mesure que le soleil descend (se couche), le point se déploie pour former un arc de cercle coloré et centré au zénith face au soleil. Pour être bien technique, lorsque le soleil est à 22,1 degrés, l'éclat de l'arc est à son maximum et il est tangent au grand halo.

OBS

Il arrive parfois que l'on observe les arcs circumzénithaux sans que le grand halo soit visible.

Subject field(s)
  • Orbital Stations
CONT

The first segment to be launched into orbit, designated Z1, will not permanently attach to other truss segments. The Z1 segment is a 10 ft (3 m) cubelike truss made from six machined bulkheads that are bolted together. The truss houses four control moment gyroscopes that form part of the guidance, navigation, and control system. The location of Z1 is nearly in the middle of the station, which makes it an ideal location for the gyroscopes. A micrometeor shield composed of three sheets of 0.25 in. (6 mm) aluminum about 5 in. (127 mm) apart protects the sensitive gyroscopes from debris. The 18,300 lb (8,300 kg) Z1 segment is currently scheduled to be launched by the end of this year. The truss is a transitional structure that will connect to the pressurized Unity module already on orbit. Astronauts will tighten 16 motorized bolts on the circular coupling on the Unity module side into nuts on Z1 and connect the associated utility plug-ins. Pressurized units generally have circular couplings and nonpressurized unit connectors are rectangular.

CONT

The Z1 truss segment is equipped with several spacewalk aids: Two EVA tool stowage devices (ETSDs), 22 worksite interface (WIF) sockets, 1 flight-releasable grapple fixture (FRGF), 11 trusses, 2 tray launch restraints, numerous standard handholds and handrails, and several custom handles.

The Columbus External Payload Facility(CEPF) is a set of structures added to the starboard end-cone of the Columbus module intended to carry four payload adapters mechanically similar to those used in the NASA ExPRESS Pallet(ExP) programme [RD 2]. Unlike the ExP, the CEPF provides one adapter location that normally points to notional zenith, one oriented to notional nadir, and two to starboard.

R bar approach of the space shuttle towards the satellite ... along the radius vector.

OBS

For visualization purposes, the station's direction of motion is called the velocity vector, or V-bar for short. By convention, points in front of the station are said to be on the positive V-bar while points behind are considered negative. The imaginary line connecting the station with the center of the Earth is called the radius vector, or R-bar. Points directly below the station along this line are considered positive while points above are considered negative. Endeavour, then, will approach the station along the plus R-bar. The station will be oriented with its long axis aligned with the velocity vector, with the Unity module in "front" and Zvezda behind. Unity's nadir and zenith ports will be oriented as their names imply. This orientation, or attitude, is known as "XVV, "i. e., the station's X axis is aligned with the velocity vector. The terminal rendezvous sequence will begin with a rocket firing(TI) as Endeavour trails the station by about eight nautical miles. Once the shuttle reaches the plus R-bar, commander Brent Jett will guide the ship up from directly below. As he nears the station, he will yaw the shuttle 180 degrees so its tail is pointing in the direction of motion and its nose toward the minus V-bar. Assuming a good linkup, the shuttle will begin controlling the station's orientation for the duration of Endeavour's mission, moving the lab back into an "X-POP" attitude with the station's X axis perpendicular to the plane of its orbit. In this orientation, the long axis of the station is broadside to the velocity vector.

A radio spectrometer has been built on Bruny Island, south of Hobart, for the study of solar bursts in the rarely observed frequency range from 3 to 20 MHz. This spectrometer is an adaptive device that employs digital techniques to avoid most of the strong terrestrial interference prevalent in this frequency range. The residual interference that cannot be avoided is excised during off-line processing. As a result, successful observations are made down to the minimum frequency that can propagate through the ionosphere to the antenna. This minimum frequency depends upon the zenith distance of the Sun and it is usually between 4 and 8 MHz.

  • Climate Change
DEF

A ratio that measures the comprehensibility of data, usually expressed as the signal power divided by the noise power, usually expressed in decibels (dB).

CONT

The detection problem can be viewed in terms of the concept of the signal-to-noise ratio, i.e. one can claim to have detected a change in climate once the signal (e.g. the increasing temperature) has risen appreciably above the background noise level (e.g. natural variability of temperature).

CONT

Signal-to-noise ratio. ... For first detection of a CO2-induced climate change, the model signal is the mean change or anomaly in some climatic variable, usually surface air temperature, attributed by a numerical model to increased concentrations of carbon dioxide. Observed noise is the standard deviation or natural variability computed from observations of that variable and adjusted for sample size, autocorrelation, and time averaging.

WIND (Wind INfrared Doppler lidar) a pour but de déterminer la vitesse d'aérosol a basse altitude (1 à 10 km) à partir d'un lidar embarqué.

Compte tenu du rapport signal à bruit (RSB) «important», supérieur à -5 dB, une modélisation approximative (notch filter) du signal lidar suffit pour obtenir des résultats satisfaisants. [...] La réalisation de l'instrument est à la charge du Laboratoire de Météorologie Dynamique (LMD).

OBS

Théorie de la détection du signal : dans cette théorie, on décrit le «signal» (stimulus à identifier ou souvenir à reconnaître) comme une distribution statistique sur un ensemble de valeurs d'abscisse, et le «bruit» (autres stimulations ou autres souvenirs) de la même façon; ce sont les relations entre ces distributions, et les critères de décision adoptés par le sujet, qui gouvernent la détection.

OBS

Cette théorie qui connaît différentes applications, en radiotélécommunication notamment mais aussi en sismologie, est également utilisée en climatologie; chacune de ces sciences a établi des critères précis afin de l'utiliser à ses propres fins. Le climat subit des variations qui répondent à des cycles connus et que la statistique permet de distinguer; les climatologues croient que ces bruits, les variations naturelles, s'ils sont d'abord identifiés permettront ensuite de laisser voir le véritable signal confirmant que l'effet de serre anthropique est bien en cours.
