INITIAL MODEL TIME [4 records]

Record 1 2026-01-08

English

Subject field(s)
  • Computer Mathematics
  • Computer Programs and Programming
  • Artificial Intelligence
CONT

First, [researchers] propose a bi-objective optimization model integrated with irregular headways under daily operations. Second, a sequential search algorithm is developed that independently optimizes the first objective to obtain an initial solution and iteratively searches the improved timetables to minimize the total transfer waiting time.

Record 2 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.

English

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

Determination of a consistent set of initial values of the variables in a numerical forecasting model using atmospheric observations.

CONT

Proper initialization is vital to insuring optimal model forecasts. Initialization is difficult because of the lack of data available on proper time and space scales and the effect and compounding importance of small initial errors.

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

Détermination d'un ensemble cohérent de valeurs initiales des variables d'un modèle de prévision numérique, à partir d'observations atmosphériques.

CONT

L'analyse de l'humidité du sol pour l'initialisation d'un modèle de prévision du temps est étudiée.

Spanish

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

Determinación de un conjunto coherente de valores de entrada de variables meteorológicas para el uso en el pronóstico numérico, a base del estado observado de la atmósfera.
