0137347/JulienThe main aims of this proposal are to develop a better understanding of mixing during the active phase of deep open-ocean convection and to obtain parameterizations of temperature and salinity changes occurring during convection. Its physical novelty is that it includes the study of physical processes not previously examined in detail, including: (a) vortical interactions between plumes and (b) slant-wise convection. The study will use ambitious numerical simulations to examine the dynamics of turbulent ensembles of convective plumes and will include the effect of the horizontal component of the Earth's rotation vector. Simulations will use both the full Boussinesq equations as well as less stiff, asymptotically reduced sets of dynamical equations developed by the PIs. The information on the lateral stirring and penetration of strong convective events in the upper ocean that will be developed in this project will be used to improve parameterizations of open-ocean convection in large-scale ocean models of the sort used to study global ocean circulation and climate.

0137347/julienthe本提案的主要目的是在深度开放式对流的活动阶段更好地理解混合，并获得对流过程中温度和盐度变化的参数化。 它的物理新颖性是它包括对以前未详细研究的物理过程的研究，包括：（a）羽毛之间的涡流相互作用和（b）倾斜的对流。 该研究将使用雄心勃勃的数值模拟来检查对流羽流的湍流集合的动力学，并包括地球旋转载体的水平成分的效果。 模拟将同时使用完整的BoussinesQ方程，以及PIS开发的动态方程的僵硬，渐近减少的集合。 该项目将在该项目中将开发的强烈对流事件的横向搅拌和渗透的信息将用于改善用于研究全球海洋循环和气候的大规模海洋模型中开放海洋对流的参数化。
