本研究的第一部分即模式设计部分．为研究大尺度海气相互作用，气候及气候变化，我们参考国外有关区域模式，设计和建立了一个有海底地形的六层斜压全球海洋环流模式．分辨率为５°经度×４°纬度，积分区域为７０°Ｓ和７０°Ｎ之间的全球海区，最大深度３７５０ｍ．模式方程为静力近似和Ｂｏｕｓｓｉｎｅｓｑ近似下的原始方程，模拟海流，温度和盐度．以年平均风应力，年平均海表热通量和盐通量作为强迫条件，从静止状态开始积分，时间足够长以后获得稳定的海流．温、盐分布．另一文将叙述模拟及试验结果．
The first part of this study is the part of pattern design. To study large-scale air-ocean interaction, climate and climate change, we design and establish a six-baroclinic global ocean circulation model with submarine topography, referring to relevant regional models abroad. The resolution is 5 ° longitude × 4 ° latitude, the integral area is between 70 ° S and 70 ° N in the global sea area, the maximum depth of 3750m. The model equation is the original equation under static approximation and Boussinesq approximation, simulating ocean currents, temperatures and salinities. Taking average annual wind stress, mean annual surface sea heat flux and salt flux as the forcing conditions, we start integrating from standstill, and obtain stable current after long enough time. Temperature, salt distribution. Another article will describe the simulation and test results.
