A typical forecast cycle over 24 hours. Every six hours, an analysis from the previous forecast run is assimilated with the six-hourly observations to initiate the next forecast. Each 12 hours, a full forecast run is performed; at 06 : 00 and 18 : 00, short forecast runs are performed to provide an analysis for the next forecast run.  1, record 1, English, - forecast%20cycle

Ensemble Prediction Systems(EPS) are numerical weather prediction(NWP) systems that allow us to estimate the uncertainty in a weather forecast as well as the most likely outcome. Instead of running the NWP model once(a deterministic forecast), the model is run many times from very slightly different initial conditions.  7, record 2, English, - ensemble%20weather%20forecast%20system

Les systèmes de prévision d'ensemble sont des systèmes de prévision numérique du temps qui nous permettent d'évaluer l'incertitude des prévisions météorologiques ainsi que leurs incidences les plus probables. Au lieu de faire tourner le modèle de prévision numérique une seule fois (prévision déterministe), on le fait tourner plusieurs fois avec des conditions initiales très légèrement différentes.  3, record 2, French, - syst%C3%A8me%20de%20pr%C3%A9vision%20m%C3%A9t%C3%A9orologique%20d%27ensemble

Forecast Models : Forecasters use numerical weather models to make their forecasts. These numerical models are classified into four main classes. The first is global models, which focus on the entire northern hemisphere. The second is national models, which focus on the USA. The third is regional models. These regional models have a finer grid than national models and are run out for smaller periods of time. The final class of models is relocatable models, which do not focus on any permanent geographical location. Relocatable models are very limited on the size of the geographical area for which they can forecast, but these models have very high resolutions, or very small forecast grid boxes.  2, record 3, English, - weather%20forecast%20model

Le modèle de prévisions SEF (Ritchie 1991) est à la base des prévisions mensuelles. Il s'agit du même modèle qui est utilisé tous les jours pour les prévisions à moyen terme (jusqu'à 10 jours), mais pour lequel quelques modifications à la dynamique et à la physique ont été apportées pour qu'il puisse fonctionner en mode climat.  3, record 3, French, - mod%C3%A8le%20de%20pr%C3%A9vision%20m%C3%A9t%C3%A9orologique
