OCE 96-18102 Tandon The project will evaluate the contribution of diurnal and seasonal cycling of the mixed layer to the transformation of water masses in the upper ocean. This represents an extension of the steady thermodynamic balance where the air- sea buoyancy flux is compensated by vertical mixing in the surface mixed layer and the advective buoyancy flux. In this study the diapycnal flux due to time-dependent (diurnal and seasonal) mixed layer deepening and entrainment will be quantified. Both data analysis and diagnostic studies of model output will be used in the investigation.

该项目将评估混合层的日循环和季节循环对上层海洋水团转变的贡献。这代表了稳定热力学平衡的延伸，在这种平衡中，海气浮力通量由表层混合层的垂直混合和平流浮力通量补偿。在这项研究中，由于时间依赖（日和季节）的混合层加深和夹带的河床通量将被量化。数据分析和模型输出的诊断研究都将用于调查。
