Abstract

One of the key problems of physical oceanology is the search for effective global mechanisms that can result in formation and sustainability of the oceanic thermohalocline, which accumulates huge amounts of heat in the middle latitudes. The study revealed a genetic relationship between this element of macroscale stratification and the intensity of vertical mixing of waters caused by double diffusion in the form of salt fingers. It has been established that the more orderly work in the ocean water column of such a small-scale process as convection of salt fingers transforms the structure of the thermohaline, due to which the transition from warm and saline surface waters to underlying waters occurs not abruptly, but rather gradually, through a stationary transition layer: the oceanic thermohalocline. The results support our viewpoint on the salt finger convection as a climate-generating factor.

盐指对流对海洋热卤代碱结构的影响

摘要

物理海洋学的关键问题之一是寻找有效的全球机制,以导致海洋热卤代碱的形成和可持续性,该热卤代碱在中纬度地区积聚大量热量。研究揭示了宏观分层的这一元素与盐指形式的双扩散引起的水垂直混合强度之间的遗传关系。已经确定的是,盐指对流这样的小规模过程在海洋水柱中的工作更加有序,从而改变了温盐的结构,因此,从温暖的盐水和盐水到地下水的过渡不会突然发生,但逐步地通过一个固定的过渡层:海洋热卤代碱。
