摘　　要：陆-海界面是地球系统科学模型边界条件设定的难点。入海物质通量测量的不确定性、逆梯度汇聚的局域化功能以及可降维自适应结构的存在,使得陆-海界面成为共振条件下连接线性与非线性系统的枢纽,难以在经典线性化理论框架下组织“各态遍历”的测量,实现界面系统的实参数化,满足地球系统科学模型的环境模拟与预测需求。受前人借助卫星高度计和潮位站等大规模水位数据阵列的伴随同化,运用陆架潮波数值模型反演海底边界层拖曳系数时空变化规律的案例启发,文章提出了陆-海界面系统的复参数化思维以及遥感观测和数值模型相结合的复参数化建议。Land-ocean interface has been a challenge in determining the boundary conditions for earth system modelling.Due to the uncertainty of material fluxes,the localization effect on counter gradient convergence,and the existence of self-adapted structures,land-ocean interface is unable to be monitored ergodically under the framework of classic linear theory.There is a great difficulty in quantifying real parameters for this interface,which is the key connection between linear and nonlinear systems under harmonic conditions,to better improve the simulation and prediction capability of earth system modelling.In a previous work,based on a two-dimensional multi-constituent tidal model and its adjoint model,together with assimilation using satellite altimeter data and tidal gauge array data,the spatial and temporal variation in bottom friction coefficient was estimated in an improved way.Inspired by the abovementioned study,this contribution proposed a suggestion of complex parameterization for land-ocean interface,in combination with remote sensing observation and numerical modelling.
