Abstract
In this investigation, the General Ocean Turbulent Model (GOTM) was used for the investigation of turbulent processes of a water column over a study site in the Oman Sea. The used method appropriately reproduces the main features of the study area, allows for a realistic view of the turbulence, and thus makes it possible to compare the Mixed Layer Depth (MLD) in all seasons. The MLD varies from 150 m in spring to 200 m in autumn. This simulation presented that the production of Turbulent Kinetic Energy (TKE) in the seawater column in the Oman Sea has seasonal changes. In the surface layer, TKE is small which is produced by low quantities of shear production, then it is conserved by the wind stress on the mixed layer and buoyancy production. In the deep layer, TKE is produced only by buoyancy. Calculated Prandtl number in all seasons presented that the turbulent diffusivity of temperature is dominant in most parts of water column, except in a thin layer which forms approximately between the depths of 150–200 m.
AbstractIn this investigation, the General Ocean Turbulent Model (GOTM) was used for the investigation of turbulent processes of a water column over a study site in the Oman Sea.所使用的方法恰当地再现了研究区域的主要特征,可以真实地观察湍流,从而可以比较各个季节的混合层深度(MLD)。混合层深度从春季的 150 米到秋季的 200 米不等。模拟结果表明,阿曼海海水柱中产生的湍流动能(TKE)具有季节性变化。在表层,TKE 较小,由少量剪切力产生,然后由混合层上的风应力和浮力产生来保持。在深层,TKE 仅由浮力产生。所有季节的普朗特尔数计算结果都表明,在水柱的大部分区域,温度的湍流扩散性占主导地位,只有大约在 150-200 米水深之间形成的薄层除外。
期刊介绍:
Water Resources is a journal that publishes articles on the assessment of water resources, integrated water resource use, water quality, and environmental protection. The journal covers many areas of research, including prediction of variations in continental water resources and regime; hydrophysical, hydrodynamic, hydrochemical and hydrobiological processes, environmental aspects of water quality and protection; economic, social, and legal aspects of water-resource development; and experimental methods of studies.
