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 1, 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 1, French, - syst%C3%A8me%20de%20pr%C3%A9vision%20m%C3%A9t%C3%A9orologique%20d%27ensemble

Model output statistics... have often taken the form of multilinear regression equations derived by screening potential model-forecast variables as predictors.

The difference between model output statistics (MOS) and perfect prognostic is that in MOS the predictand is related to the actual model output, while in perfect prog, the predictand is related to observations or representations of them at (nearly) concurrent times. 3, record 3, English, - model%20output%20statistics

In advance of the scientific research on the numerical modeling study, it is absolutely necessary to check the model output first. For the mesoscale modeling, the observational data with high temporal and spatial resolution are needed to check the model output besides the conventional data, which can be got from such as satellite, radar, aircraft, drop-sounding, wind profilers and automated meso-net weather stations etc. 2, record 4, English, - dropsounding

Un procédé comparable est celui du catasondage qui consiste à larguer d'un aéronef un système analogue à la radiosonde mais qui tombe en chute libre et dont la vitesse est stabilisée et régularisée par diverses méthodes. Les mesures de la catasonde, également diffusées par un émetteur radioélectrique, sont recueillies par l'aéronef qui l'a larguée. C'est en utilisant de tels dispositifs que sont prospectées certaines perturbations particulièrement actives tels que les cyclones tropicaux. 1, record 4, French, - catasondage

La zone la plus à l'Est [de l'Atlantique] a été appelée la «Multiscale Sampling Area» (MSA). C'est dans cette région que les cyclones, alors en phase mature, et les systèmes nuageux associés ont été échantillonnés à différentes échelles. Ces échantillonnages ont été rendus possible par un renforcement des moyens instrumentaux avec notamment deux radars Doppler double faisceau aéroportés en bande X (sur le NOAA-P3 et le NCAR Electra [...] et des dropsondages effectués avec une haute résolution (largués du UK-C130).

The Working Group on Numerical Experimentation(WGNE), jointly established by the Joint Scientific Committee on the WCRP and the WMO Commission for Atmospheric Sciences(CAS) has the responsibility of fostering the development of atmospheric circulation models for use in weather prediction and climate studies on all time scales and diagnosing shortcomings. WGNE promotes co-ordinated numerical experimentation for validating model results, observed atmospheric properties, exploring the natural and forced variability and predictability of the atmosphere,(e. g the Atmospheric Model Intercomparison Project, AMIP), as well as studies aimed at refined numerical techniques, and the formulation of atmospheric physics processes. WGNE also monitors the advances in data assimilation and analysis methods and is the focal point in WCRP for encouraging and reviewing the reanalysis projects carried out at various centres with fixed state-of-the-art assimilation systems providing a multi-year homogenous data set for a range of atmospheric and climate diagnostic studies. 2, record 5, English, - Working%20Group%20on%20Numerical%20Experimentation
