Model of Estuaries and Coastal Oceans (MECO)

Model of Estuaries and Coastal Oceans (MECO) is a a three dimensional, non-linear, variable density, hydrodynamic model. It is intended to be a general purpose hydrodynamic model for estuaries and coastal oceans providing distributions of velocity, temperature and salinity as well as concentrations of passive tracers given input fluxes of water, passive tracers and forcing by winds, atmospheric pressure gradients, tides and surface heat fluxes. The equations forming the basis of the model are similar to those described in Blumberg and Herring (1987), except that the model uses z-coordinates, rather than sigma coordinates in the vertical. MECO is written in the C language, and uses the netCDF data format for input and output files. The MECO model has evolved into the Sparse Hydrodynamic Ocean Code (SHOC). SHOC has been in use since 2003 and is the hydrodynamic model used by the Coastal Environmental Modelling Team (CEM). Information regarding SHOC can be found at the CEM website.

河口与近岸海洋模型（Model of Estuaries and Coastal Oceans，缩写MECO）是一款三维、非线性、变密度水动力模型。该模型旨在成为面向河口与近岸海洋的通用型水动力模型，可在输入水通量、被动示踪剂通量，以及风场、大气压强梯度、潮汐和海面热通量等强迫驱动数据后，输出流速、温度、盐度的分布场及被动示踪剂浓度分布。支撑该模型的控制方程与Blumberg和Herring（1987）文献中描述的方程基本一致，仅在垂直方向采用z坐标系，而非σ坐标系。MECO采用C语言编写，其输入与输出文件均采用网络通用数据格式（netCDF）。MECO模型后续迭代发展为稀疏水动力海洋代码（Sparse Hydrodynamic Ocean Code，缩写SHOC）。SHOC自2003年起投入使用，是海岸环境建模团队（Coastal Environmental Modelling Team，缩写CEM）所采用的水动力模型。有关SHOC的详细信息可访问CEM官网（详见下方链接）。
