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.  3, record 1, English, - medium%2Drange%20weather%20forecasting

Hypersonic propulsion. Color Enhanced Supersonic Hydrogen Flame Through funding from the Hyper-X Program Office at NASA Langley, an experimental study of a dual-mode scramjet combustor is being conducted at the Aerospace Research Laboratory of the University of Virginia. Using conventional instrumentation and multiple laser-based diagnostic techniques, the study aims to further the understanding of the fuel-air mixing and combustion processes within the combustor and to resolve the uncertainty in CFD predictions of such flows. The majority of the experiments are being conducted using a high-enthalpy, continuous-flow facility. This facility simulates Mach 5 flight of a scramjet operating with ramp fuel injection of hydrogen. NASA Langley is performing numerical modeling of the combustor and these results are being compared with the experimental measurements.  2, record 3, English, - hypersonic%20propulsion

Depuis une dizaine d'années, la recherche aéronautique s'intéresse à la propulsion hypersonique, permettant d'atteindre des vitesses supérieures à Mach 6. [...] La technologie de motorisation privilégiée pour la propulsion hypersonique est le statoréacteur, dont la particularité est qu'il n'embarque pas de comburant à bord mais capte celui-ci dans l'air environnant : l'air est capté en amont du moteur et comprimé par un système de tuyère convergente. Le mélange carburant embarqué-air comprimé brûle dans la chambre de combustion avant d'être décomprimé, provoquant ainsi l'accélération des gaz et la poussée nécessaire au vol.  2, record 3, French, - propulsion%20hypersonique

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 7, 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 7, 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). D'autre part ces avions étaient équipés de capteurs in-situ (microphysique et dynamique) et d'un radar ventral en bande C (pour le NOAA-P3).  2, record 7, French, - catasondage
