Mesoscale phenomena are ubiquitous and highly energetic features of ocean circulation. Their influence on biological and biogeochemical processes varies widely, stemming not only from advective transport but also from the generation of variations in the environment that affect biological and chemical rates. The ephemeral nature of mesoscale features in the ocean makes it difficult to elucidate the attendant mechanisms of physical-biological-biogeochemical interaction, necessitating the use of multidisciplinary approaches involving in situ observations, remote sensing, and modeling. All three aspects are woven through this review in an attempt to synthesize current understanding of the topic, with particular emphasis on novel developments in recent years.

With the continuous development of space and sensor technologies during the last 40 years, ocean remote sensing has entered into the big-data era with typical five-V (volume, variety, value, velocity and veracity) characteristics. Ocean remote-sensing data archives reach several tens of petabytes and massive satellite data are acquired worldwide daily. To precisely, efficiently and intelligently mine the useful information submerged in such ocean remote-sensing data sets is a big challenge. Deep learning-a powerful technology recently emerging in the machine-learning field-has demonstrated its more significant superiority over traditional physical- or statistical-based algorithms for image-information extraction in many industrial-field applications and starts to draw interest in ocean remote-sensing applications. In this review paper, we first systematically reviewed two deep-learning frameworks that carry out ocean remote-sensing-image classifications and then presented eight typical applications in ocean internal-wave/eddy/oil-spill/coastal-inundation/sea-ice/green-algae/ship/coral-reef mapping from different types of ocean remote-sensing imagery to show how effective these deep-learning frameworks are. Researchers can also readily modify these existing frameworks for information mining of other kinds of remote-sensing imagery.© The Author(s) 2020.

In recent years, deep artificial neural networks (including recurrent ones) have won numerous contests in pattern recognition and machine learning. This historical survey compactly summarizes relevant work, much of it from the previous millennium. Shallow and Deep Learners are distinguished by the depth of their credit assignment paths, which are chains of possibly learnable, causal links between actions and effects. I review deep supervised learning (also recapitulating the history of backpropagation), unsupervised learning, reinforcement learning & evolutionary computation, and indirect search for short programs encoding deep and large networks.

Ocean models routinely used in simulations of the Earth's climate do not resolve mesoscale eddies because of the immense computational cost. A new parameterization of the effects of these eddies has been implemented in a widely used model. A comparison of its solution with that of the conventional parameterization shows significant improvements in the global temperature distribution, the poleward and surface heat fluxes, and the locations of deep-water formation.

物理过程参数化方案的不确定性是目前气候系统模式不确定性的重要来源之一.随着模式内在复杂度攀升,模拟场景多样化,参数化方案中基于先验的和人工的物理参数选取方法已经逐步成为限制模式模拟能力的瓶颈之一.为此,本文设计并提出了初选与寻优相结合的两步法参数优化方案.初选阶段用全因子采样方法对不确定参数空间进行初始敏感性分析,估计最优解所在区域;寻优步采用单纯型下山法,基于初选阶段确定的参数组合快速寻优.将两步法应用于中国科学院大气物理研究所(英文缩写:IAP)大气科学和地球流体力学数值模拟国家重点实验室(英文缩写:LASG)格点大气模式第2版:GAMIL2,选取其深对流方案和云量方案中的3个重要参数开展寻优,优化以综合减小模式降水、风场、温度、湿度、位势高度以及辐射通量的误差为目标.这些变量用GAMIL2标准版本标准化后形成单一的目标. 结果显示,优化后的目标函数值比GAMIL2 标准版本改进了7.5%.机理分析表明,调优后的参数优化了大气中的水汽凝结作用,进而减少模式的湿度偏差,改进云量的模拟效果;同时水汽凝结作用的变化通过大气内部动力和热力相互作用及响应影响温度、位势高度和风场的模拟.

In this investigation, a data-driven turbulence closure framework is introduced and deployed for the subgrid modelling of Kraichnan turbulence. The novelty of the proposed method lies in the fact that snapshots from high-fidelity numerical data are used to inform artificial neural networks for predicting the turbulence source term through localized grid-resolved information. In particular, our proposed methodology successfully establishes a map between inputs given by stencils of the vorticity and the streamfunction along with information from two well-known eddy-viscosity kernels. Through this we predict the subgrid vorticity forcing in a temporally and spatially dynamic fashion. Our study is both a priori and a posteriori in nature. In the former, we present an extensive hyper-parameter optimization analysis in addition to learning quantification through probability-density-function-based validation of subgrid predictions. In the latter, we analyse the performance of our framework for flow evolution in a classical decaying two-dimensional turbulence test case in the presence of errors related to temporal and spatial discretization. Statistical assessments in the form of angle-averaged kinetic energy spectra demonstrate the promise of the proposed methodology for subgrid quantity inference. In addition, it is also observed that some measure of a posteriori error must be considered during optimal model selection for greater accuracy. The results in this article thus represent a promising development in the formalization of a framework for generation of heuristic-free turbulence closures from data.

数字孪生模型能够有效地促进实际产品与产品模型间的虚实交互。针对调心滚子轴承套圈磨削过程中的磨削力,通过对磨削工作区各构件进行动力学与接触算法建模以及刚柔耦合处理,构建了轴承套圈沟道磨削加工数字孪生模型,完成了轴承套圈磨削工作区域在数字空间中的虚拟映射。并使用该模型对砂轮线速度、工件转速等工艺参数进行了分析与试验,证明了所构建数字孪生模型具有一定的有效性。该模型具有高保真性,可用于理解、预测和优化真实系统。
The digital twin model can effectively promote the virtual-real interaction between the actual product and the product model. Aiming at the grinding force generated in the grinding process of spherical roller bearings, this paper constructs the bearing ring raceway grinding process by performing dynamics, contact algorithm modeling and rigid-flexible coupling treatment on the components of the grinding work area. The digital twin model completes the virtual mapping of the grinding work area of the bearing ring in the digital space. The model is used to analyze and test the process parameters such as the grinding wheel linear speed and the workpiece speed, which proves the validity of the digital twin model constructed. The model has high fidelity and can be used to understand, predict and optimize real systems. |

从实景三维建模到数字孪生建模是国家数字经济和智慧社会建设与发展的基本需求。本文探讨了实景三维建模和数字孪生建模的关键技术内涵,介绍了数字乡村、未来社区和智能铁路等典型应用场景。广域范围实景三维建模在低成本高效数据采集和智能化自动化三维精细建模与动态更新方面面临挑战,城市级或重大工程级的数字孪生建模在全要素整体性的表征数据与机理模型集成表达方面还存在关键技术瓶颈。测绘技术亟须多学科交叉融合创新,突破天空地有机协同实时动态获取多细节层级实景三维数据、智能化处理多专业多尺度多模态时空数据、不完备数据条件下复杂场景的三维实体化精细建模、表征数据与机理模型结合的全生命周期数字孪生模型动态构建等核心关键技术,形成通用地理空间智能,实现测绘技术的高质量发展和对经济社会发展不可替代的更有力的基础支撑。
From real 3D modeling to digital twin modeling is the basic requirement for the construction and development of the country's digital economy and smart society. This paper discusses the connotations and key technologies of real 3D modeling and digital twin modeling, and introduces three typical application scenarios: digital villages, future communities and intelligent railways. Wide-area real 3D modeling is facing challenges in low-cost and efficient data collection and intelligent automated modeling and dynamic updating. There are still key technical bottlenecks in the integrated expression of all-element holistic representation data and mechanism models for digital twin modeling at the city level or major engineering level. Surveying and mapping technology is in urgent need of multi-disciplinary cross-integration innovation, breakthroughs in organic collaboration between the sky and the ground, real-time and dynamic acquisition of multi-detailed real 3D data, automated intelligent processing of multi-specialty, multi-scale and multi-modal spatio-temporal data, and detailed 3D construction of complex scenes under incomplete data conditions. Core key technologies such as dynamic construction of full-life-cycle digital twin models that combine characterization data and mechanism models to form general geospatial intelligence to achieve high-quality development of surveying and mapping technology and an irreplaceable and more powerful basic support for economic and social development.
