从流体动力学的角度来看，狮子湾可以被认为是一个非常复杂的区域，因为几个激烈和高度可变的现象同时竞争。 这些过程包括沿大陆坡沿着的强大环流、大陆架和近海稠密水的形成、分层的季节性变化以及与气象条件有关的极端能量。 地中海西北部普遍无云的大气条件使我们能够在10多年的时间里大量利用各种卫星图像。 水动力特征在空间和时间上的变化很大，地形复杂，捕鱼活动明显，这给现场观测数据的收集带来了一定的困难。 因此，我们只获得了几个斜坡上的海流时间序列;在大陆架上获得的海流时间序列只包括夏季。 模型已经被详细阐述，以帮助我们理解大气环流的原因。 今后几年将开展的观测方案可能会为我们提供关于狮子湾流体动力学的更确定的结果。
From an hydrodynamical point of view, the Gulf of Lions can be considered as a very complex region, because several intense and highly variable phenomena compete simultaneously. These processes include the powerful general circulation along the continental slope, the formation of dense water both on the shelf and offshore, a seasonal variation of stratification and the extreme energies associated with meteorological conditions. The cloudless atmospheric conditions encountered generally in the northwestern Mediterranean Sea have enabled us to make use of, over more than 10 years, large use of various satellite imageries. The large space and time variability of the hydrodynamical features, a complex topography and a noticeable fishing activity, represent certain difficulties to the collection of observations in situ. We have obtained, therefore, only a few current time series on the slope; those obtained on the shelf only cover the summer period. Models have been elaborated to help us understand the reasons for the general circulation. Observational programmes to be carried out in the forthcoming years will probably provide us with more definitive results on the Gulf of Lions' hydrodynamics.
