Record 1 2015-03-11

English

Subject field(s)
  • Meteorological Forecasting, Data Measurement and Analysis
DEF

Numerical model based on an hypothetical barotropic atmosphere. This model takes no account of vertical wind shears and horizontal temperature gradients; therefore, the growth of disturbances through conversion of potential to kinetic energy cannot be predicted. It yields a prediction at only one level (generally 500 hPa).

French

Domaine(s)
  • Prévisions météorologiques et mesure et analyse des données
DEF

Modèle numérique basé sur une atmosphère barotrope hypothétique. Ce modèle ne tient pas compte des cisaillements verticaux du vent ni des gradients horizontaux de température; on ne peut donc prévoir le développement de perturbations par conversion d'énergie potentielle en énergie cinétique. Il fournit une prévision à un seul niveau (généralement 500 hPa).

Spanish

Campo(s) temático(s)
  • Previsiones meteorológicas, medición y análisis de datos
DEF

Modelo numérico basado en una atmósfera barotrópica hipotética. Este modelo no toma en cuenta la cizalladura vertical del viento ni los gradientes horizontales de temperatura; así pues, no puede prever el desarrollo de una perturbación por conversión de energía potencial en energía cinética. Produce predicciones de un solo nivel(generalmente 500 hPa).

Record 2 2005-06-01

English

Subject field(s)
  • Aircraft Piloting and Navigation
  • Atmospheric Physics
DEF

Change of horizontal wind direction and/or speed with height, as would be determined by means of two or more anemometers mounted at different heights on a single mast. [Definition officially approved by ICAO.]

OBS

Key term(s)

French

Domaine(s)
  • Pilotage et navigation aérienne
  • Physique de l'atmosphère
DEF

Variation de la direction horizontale et/ou de la vitesse du vent en fonction de la hauteur, telle qu'elle serait déterminée par deux ou plusieurs anémomètres montés à des hauteurs différentes sur un même pylône. [Définition uniformisée par l'OACI.]

OBS

cisaillement vertical du vent : terme normalisé par l'ISO; terme uniformisé par le Comité d'uniformisation de la terminologie aéronautique (CUTA) - Opérations aériennes et par l'Organisation de l'aviation civile internationale (OACI).

Spanish

Campo(s) temático(s)
  • Pilotaje y navegación aérea
  • Física de la atmósfera
DEF

Cambio de la dirección horizontal y/o de la velocidad del viento en función de la altura, que se determinaría mediante dos o más anemómetros montados a diferentes alturas en un mismo mástil.

Record 3 2005-05-30

English

Subject field(s)
  • Meteorological Forecasting, Data Measurement and Analysis
DEF

The derivative of any vector in any spatial direction.

CONT

The shear vector is the difference in the wind vector between two different heights. Both the wind and the shear vector may change with height, either veering or backing.

CONT

For example, a 10 knot SE wind with a 30 knot NW wind above it should produce a SHEAR VECTOR of 20 knots from the NW.

OBS

shear vector. ... The particular direction should be clear from the context.

OBS

vector - A quantity that has both a magnitude and direction. May also be used as a heading and speed in aviation, or as a location on a chart, map, or computer based graphic. Windspeed and its direction is an example of a VECTOR measurement.

French

Domaine(s)
  • Prévisions météorologiques et mesure et analyse des données
CONT

Cisaillement cyclonique [...] Cisaillement vertical tel que la rotation du vecteur vent vers le vecteur de cisaillement en un point particulier est cyclonique.

Spanish

Campo(s) temático(s)
  • Previsiones meteorológicas, medición y análisis de datos
CONT

cizalladura ciclónica :Cizalladura vertical en un punto en que el giro del vector viento al vector de la cizalladura tiene sentido ciclónico.

English

Subject field(s)
  • Atmospheric Physics
DEF

Term sometimes applied to the trade winds when they are shallow and show pronounced vertical wind shear.

CONT

Easterly winds over the tropics and subtropics incorporate wave-like disturbances which usually travel westward. Important features of the tropical easterlies include the southeast trade winds, monsoon lows and sometimes tropical cyclones (known as hurricanes in the Americas and typhoons in Asia).

OBS

tropical easterlies: term rarely used in the singular (tropical easterly).

Key term(s)
  • tropical easterly

French

Domaine(s)
  • Physique de l'atmosphère
DEF

Terme parfois appliqué aux alizés de faible épaisseur et présentant un fort cisaillement vertical du vent.

OBS

Término aplicado, a veces, a los alisios cuando son poco profundos y poseen una fuerte cizalladura vertical del viento.

Key term(s)

Record 6 2004-10-01

English

Subject field(s)
  • Atmospheric Physics
DEF

Term sometimes applied to the trade winds when they are shallow and show pronounced vertical wind shear.

CONT

A high pressure area over Antarctica -- associated with extremely cold and dense air is ringed by easterly winds which form the boundary with the subpolar low pressure belt. These typical features vary in intensity and location according to the season. For instance, in summer the high pressure belt is usually found just south of Australia, while the subtropical easterlies cover most of the continent.

OBS

subtropical easterlies: term rarely used in the singular (subtropical easterly).

Key term(s)
  • subtropical easterly
  • sub-tropical easterlies
  • sub-tropical easterly

French
