Les ouragans en mer Méditerranée sont des événements météorologiques extrêmes qui influencent les propriétés physico-chimiques de la colonne d’eau. Ce travail s’est concentré sur trois variables : la température, la salinité et la concentration en oxygène dissous pour le Medicane “Apollo” qui a eu lieu fin octobre 2021. Leur évolution est mesurée à l’aide d’appareils in situ (flotteurs Argo et bouées dérivantes) et par satellites. Les données satellites ont subi une reconstruction à l’aide du logiciel DINEOF, qui permet de combler des données manquantes dues à la présence de nuages par exemple. De manière générale, la température et la salinité diminuent dans la couche de mélange lors du passage du Medicane. La concentration en oxygène dissous augmente dans la couche de mélange tout comme la profondeur du maximum de concentration en oxygène dissous. Les principales raisons de ces évolutions sont les échanges enthalpiques et l’évaporation à la surface, les importantes précipitations et les vents engendrées par le Medicane, ainsi que les courants marins et le rayonnement solaire à cette période de l’année. La diminution de la température liée au passage du cyclone augmente également la dissolution de l’oxygène. Une comparaison entre les données in situ et satellitaire montre la complémentarité des deux types de mesures.

Noise generated by aircraft continues to be a pressing issue for society, as an increasing number of people residing in close proximity to airports make noise complaints on a regular basis. The reduction in aircraft noise is therefore a very important engineering task that would require the careful identification of different acoustic sources around the airplane, the understanding of noise source behavior and ranking along flight trajectories, sophisticated measurement techniques, and robust and accurate numerical tools aimed at predicting the generation of noise, the propagation through the atmosphere, and the resulting noise impact along approach and departure flights. For an overall assessment of the situation, it has to be assessed along entire flight trajectories rather than assessing limited operating conditions only. Furthermore, it is highly recommended to apply multiple acoustic metrics and account for different and widespread observer locations along the flight. Only then can the overall situation be adequately captured. Obviously, this is a highly multidisciplinary effort and no single discipline can address this problem. This reprint includes selected research studies with that multidisciplinary context that deal with numerical or experimental investigations that range from the investigation of specific noise sources to the assessment of noise generated by the overall aircraft in operation. Both basic and applied research studies involving the modelling and simulation of aircraft noise are included.
