NUMERICAL WEATHER FORECASTING [8 records]

Record 1 2023-03-24

English

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

With the apparent successes of deep learning in modeling high-dimensional data in other domains such as computer vision and natural language processing, a natural question to ask is whether numerical weather models can also be learned purely from data. This question sparked some debate after initial studies showed the general feasibility of such an approach for medium-range weather forecasting.

Key term(s)
  • medium range weather forecasting
  • medium term weather forecasting

French

Domaine(s)
  • Prévisions météorologiques et mesure et analyse des données
Key term(s)
  • prévision météo à moyen terme
  • prévision météo à moyenne échéance

Record 2 2003-09-11

English

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

The forecast centre located in Reading (England) and formed by a group of European countries as a joint venture to carry out research into improving weather forecasting for up to 10 days in advance and to produce such forecasts on an operational basis.

OBS

The principal objectives of the Centre are : the development of numerical methods for medium-range weather forecasting; the preparation, on a regular basis, of medium-range weather forecasts for distribution to the meteorological services of the Member States; scientific and technical research directed to the improvement of these forecasts; collection and storage of appropriate meteorological data.

Record 3 2002-03-18

English

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

The use of an SST [sea surface temperature] analysis in numerical weather prediction(NWP) imposes requirements which differ in some ways from other applications such as climate studies or dynamic extended range forecasting.

OBS

extended forecast: Forecast for a period generally extending beyond the normal range of the operational forecast.

Key term(s)
  • dynamic extended range forecast
  • dynamical extended-range forecast
  • dynamical extended range forecast
  • dynamical extended-range forecasting

French

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

Les analyses d'une fonction orthogonale empirique (FOE) et de la décomposition en valeur singulière (DVS) sont appliquées à l'ensemble de données de la prévision dynamique à moyenne échéance 90 (PDME90) dans le but de trouver les configurations et les régions les plus prévisibles, pour des champs de hauteur géopotentielle à 500mb sur l'hémisphère Nord non hivernal.

OBS

prévision à échéance prolongée; prévision étendue : Prévision pour une période qui s'étend généralement au-delà de l'échéance opérationnelle normale.

Record 4 1995-11-21

English

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

Forecasting method based on statistical relationships, derived over a long period of time, between locally observed weather elements and output parameters of a numerical prediction model.

OBS

The method thus takes account of local climate and any bias in the model.

French

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

Méthode de prévision basée sur des relations statistiques, obtenues sur une longue période de temps, entre les éléments météorologiques observés localement et les paramètres de sortie d'un modèle de prévision numérique.

OBS

La méthode tient ainsi compte du climat local et des biais possibles du modèle.

DEF

Método de predicción basado en relaciones estadísticas, obtenidas en un largo período de tiempo, entre los elementos meteorológicos observados localmente y los parámetros de salida de un modelo de predicción numérica.

OBS

De esta manera, el método tiene en cuenta tanto el clima local como las desviaciones posibles del modelo.
