Record 1 2023-01-31

English

Subject field(s)
  • Meteorology
  • Mathematics
DEF

A model composed of adjoint equations that maps a sensitivity gradient vector... from a forecast time... to an earlier time... which can be the initial time of a forecast trajectory.

CONT

The adjoint model, which is used in four-dimensional variational assimilation of meteorological data, can also help to investigate the sensitivity of forecast error to initial conditions in a diagnostic manner.

French

Domaine(s)
  • Météorologie
  • Mathématiques
CONT

Le modèle adjoint, qui est utilisé pour mettre en œuvre l'assimilation variationnelle quadridimensionnelle de données météorologiques, peut également servir à évaluer la sensibilité de l'erreur de prévision aux conditions initiales.

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

[The] BAM(Beta and Advection) model follows a trajectory from the Aviation Run of the MRF [medium range forecast] model to provide a track forecast.... The BAM model is run with shallow(850-700 hPa [hectopascals]), medium(850-400 hPa) and deep(850-200 hPa) vertically averaged winds models.

PHR

Record 3 2003-11-12

English

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

Determination of the position of a hurricane at successive times, by radar or satellite or some other means, in order to draw its trajectory on a chart and forecast its probable positions.

CONT

Hurricane tracking and estimation in the United States is centered in the federal government’s [National Oceanic and Atmospheric Administration (NOAA]) National Hurricane Center in Coral Gables, Florida.

OBS

NOAA National Hurricane Center - maintains a continuous watch on tropical cyclones over the Atlantic, Caribbean, Gulf of Mexico and the Eastern Pacific from May 15 through November 30.

French

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

Détection et analyse, au moyen d'un radar, des phénomènes météorologiques fournissant un écho radioélectrique (régions de précipitations de type averse).

CONT

[...] National Hurricane Center (Etats-Unis), une agence de surveillance des ouragans, couvrant en particulier la zone caraïbe.

OBS

Le [Centre canadien de télédétection] (CCT) a mis sur pied un programme nommé «Surveillance des ouragans» impliquant l'acquisition d'images RADARSAT en mode ScanSAR faisceau large (SCW) durant la saison des ouragans du Bassin de l'Atlantique pour 1999 (soit d'août à octobre inclusivement). L'Agence spatiale canadienne (ASC) et les Atlantic Oceanographic Meteorological Laboratories (AOML) de la NOAA collaborent avec le CCT dans le cadre de ce projet.

Spanish

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

Determinación de la posición de un huracán a horas sucesivas, por medio de radar u otro método, con objeto de poder trazar en un mapa su trayectoria presente y deducir las probables posiciones futuras.
