摘要：颗粒有机碳（POC）的垂直通量是海洋碳循环的核心，但对流 POC 传输的作用和年际变化仍然受到很少的限制。在拉布拉多海和伊尔明格海漂流的自主剖面仪在 2014 年至 2017 年的强对流期间检测到冬春叶绿素 a 荧光峰值在 1000 米处反复出现。颗粒的生物光学特性表明，表面 POC 富含不稳定的浮游植物物质，与背景悬浮颗粒和下沉聚集体不同，深度混合。模型模拟表明，混合驱动的向深海（500 至 2000 米）提供的 POC 与对流量 (R 2 ≈ 0. 88) 成正比，并且通常以浮游生物量为主。 根据该模型，在强对流年份，垂直混合区域性贡献了混合和下沉到 500 至 2000 米层的 POC 总供应量的 33 至 44%。这些对流注入事件可能通过增强新陈代谢和驱动横向输出来重塑深海碳预算，将上层海洋动态与深海水团和生态系统联系起来。
Abstract: Vertical fluxes of particulate organic carbon (POC) are central to the oceanic carbon cycle, yet the role and interannual variability of convective POC transport remain poorly constrained. Autonomous profilers drifting in the Labrador and Irminger Seas detected recurrent winter-spring chlorophyll a fluorescence peaks at 1000 meters during intense convection in 2014–2017. The bio-optical properties of the particles indicate deep mixing of surface POC rich in labile phytoplanktonic material, distinct from both background suspended particles and sinking aggregates. Model simulations show that the mixing-driven POC supply to the deep ocean (500 to 2000 meters) scales with convection volume ( R 2 ≈ 0.88) and is typically dominated by planktonic biomass. According to the model, vertical mixing regionally contributes ∼33 to 44% of the combined POC supply from mixing and sinking to the 500 to 2000–meter layer during strong convection years. These convective injection episodes likely reshape deep-ocean carbon budgets by enhancing metabolism and driving lateral exports, linking upper-ocean dynamics to deep-ocean water masses and ecosystems.

摘要：全球海洋预报旨在预测温度、盐度和洋流等关键海洋变量，这对于理解和描述海洋现象至关重要。近年来，数据驱动的基于深度学习的海洋预报模型，如羲河、文海、琅琊和AI-GOMS等，在捕捉复杂海洋动态和提高预报效率方面表现出了巨大的潜力。尽管取得了这些进步，但缺乏开源、标准化的基准导致数据使用和评估方法不一致。这种差距阻碍了高效的模型开发，阻碍了公平的性能比较，并限制了跨学科合作。 为了应对这一挑战，我们提出了 OceanForecastBench，这是一个提供三个核心贡献的基准：（a）用于模型训练的 28 年高质量全球海洋再分析数据，包括跨 23 个深度级别的 4 个海洋变量和 4 个海面变量。 (b) 用于模型评估的高可靠性卫星和现场观测，覆盖全球海洋中约 1 亿个地点。 (c) 评估流程和综合基准，包含 5 个典型基线模型，利用观察结果从多个角度评估模型性能。 OceanForecastBench 代表了目前可用于数据驱动的海洋预测的最全面的基准测试框架，为模型开发、评估和比较提供了一个开源平台。数据集和代码可公开获取：https://github。 com/Ocean-Intelligent-Forecasting/OceanForecastBench 。
Abstract: Global ocean forecasting aims to predict key ocean variables such as temperature, salinity, and currents, which is essential for understanding and describing oceanic phenomena. In recent years, data‐driven deep learning‐based ocean forecast models, such as XiHe, WenHai, LangYa and AI‐GOMS, have demonstrated significant potential in capturing complex ocean dynamics and improving forecasting efficiency. Despite these advancements, the absence of open‐source, standardized benchmarks has led to inconsistent data usage and evaluation methods. This gap hinders efficient model development, impedes fair performance comparison, and constrains interdisciplinary collaboration. To address this challenge, we propose OceanForecastBench, a benchmark offering three core contributions: (a) High‐quality global ocean reanalysis data over 28 years for model training, including 4 ocean variables across 23 depth levels and 4 sea surface variables. (b) High‐reliability satellite and in situ observations for model evaluation, covering approximately 100 million locations in the global ocean. (c) An evaluation pipeline and a comprehensive benchmark with 5 typical baseline models, leveraging observations to evaluate model performance from multiple perspectives. OceanForecastBench represents the most comprehensive benchmarking framework currently available for data‐driven ocean forecasting, offering an open‐source platform for model development, evaluation, and comparison. The data set and code are publicly available at: https://github.com/Ocean‐Intelligent‐Forecasting/OceanForecastBench .

摘要：通过在双层准地转（QG）模型中采用条件非线性最优摄动方法，我们研究了与海面高度异常（SSHA）预测相关的中尺度涡流目标观测的敏感区域，并揭示了其明显的纬度依赖性。我们的结果表明，不同纬度带的涡流敏感区域的空间特征可能存在显着差异，尽管这些区域通常位于具有明显的高低速度梯度的区域，且速度沿涡旋旋转方向在空间上减小。对于高纬度地区的涡流，敏感区域主要位于涡旋内表现出最明显的高低速梯度的区域。 然而，在低纬度地区，灵敏度不仅仅取决于速度梯度的大小；相反，梯度区域内的纬向速度方向也起着至关重要的作用。具体来说，敏感区域优先出现在高到低速度梯度与向东速度分量一致的地方，即使梯度相对较弱。观测系统模拟实验进一步证实，在特定纬度范围内确定的敏感区域优先进行数据同化可显着提高 SSHA 预报技能。从动力学角度来看，依赖于纬度的敏感度模式可以用行星效应调节的正压不稳定性来物理解释。 这些发现为优化现实海洋环境中的有针对性的观测策略提供了实用指导，强调了纬度在中尺度涡流观测地点选择中的关键作用，并最终增强了SSHA的预报能力。
Abstract: By employing the conditional nonlinear optimal perturbation approach within a two‐layer quasigeostrophic (QG) model, we investigate the sensitive areas for targeted observations of mesoscale eddies relevant to sea surface height anomaly (SSHA) forecasting and reveal their pronounced latitude dependence. Our results show that the spatial characteristics of sensitive areas may differ markedly among eddies located in different latitudinal bands, although these areas are generally situated in regions characterized by clear high‐to low‐velocity gradients, with velocity decreasing spatially along the direction of eddy rotation. For eddies at high latitudes, sensitive areas are primarily located in regions exhibiting the most pronounced high‐to low‐velocity gradients within the vortex. However, at low latitudes, the sensitivity is not determined solely by the magnitude of the velocity gradient; instead, the zonal velocity direction within the gradient region also plays a crucial role. Specifically, sensitive areas preferentially emerge where high‐to low‐velocity gradients coincide with an eastward velocity component, even when the gradients are relatively weaker. Observing system simulation experiments further confirm that prioritizing data assimilation in the identified sensitive areas within specific latitudinal regimes significantly improves SSHA forecast skill. From a dynamical perspective, the latitude‐dependent sensitivity patterns can be physically interpreted in terms of barotropic instability modulated by the planetary ‐effect. These findings provide practical guidance for optimizing targeted observation strategies in realistic oceanic settings, highlighting the critical role of latitude in the selection of observation sites for mesoscale eddies and ultimately enhancing SSHA forecasting capability.

摘要：本文比较了通过分析不同年份的海面温度（SST）和生物光学参数（叶绿素-a、悬浮物）的卫星图像确定的中里海东部表层水急流（从里海南部和北部到中里海的暖急流以及沿海上升流区的洋流），以及使用涡旋解析水动力模型进行的现场测量和数值模拟的已知结果。卫星监测过程中发现的两种源于南里海的急流（10月至6月沿着杰尔宾特凹陷上空气旋环流外围传播，以及7月至9月沿着东海岸大约50米等深线传播）的时空特征与数值模拟结果之间存在良好的一致性。 利用 GHRSST（高分辨率海表温度小组）项目的每日海表温度地图，南里海急流的运动于 2014 年 8 月追踪到佩斯卡尼角附近的纬度，然后以海表温度较低的较细的急流形式到达图布-卡拉干半岛的南部海岸。根据海表温度图估计的南里海急流传播速度（在其向北前进的不同阶段约为12-22厘米/秒）也与模型估计的月平均速度（约8-12厘米/秒）非常吻合。 2003 年 9 月连续卫星图像中观察到的横向上升流急流不寻常的向北传播，可以通过考虑在不利于上升流的风期间对当前结构的已知仪器测量来解释。 讨论了北里海急流在中里海东海岸附近从秋布-卡拉干半岛向南传播的卫星监测结果和数值模拟结果之间的主要异同。
Abstract: This paper compares jet currents of surface waters in the eastern Middle Caspian (warm jet streams from the Southern and Northern Caspian to the Middle Caspian and currents in the coastal upwelling zone), identified through the analysis of satellite images of sea surface temperature (SST) and biooptical parameters (chlorophyll-a, suspended matter) from different years, with known results of in-situ measurements and numerical modeling using eddy-resolving hydrodynamic models. Good agreement is noted between the spatiotemporal characteristics of two types of jets of the Southern Caspian origin (propagating along the periphery of the cyclonic gyre over the Derbent Depression in October–June and along the eastern coast within approximately the 50-meter isobath in July–September), identified during satellite monitoring, and the results of numerical modeling. Using daily SST maps from the GHRSST (The Group for High Resolution Sea Surface Temperature) project, the movement of the South Caspian water jet was traced in August 2014 to approximately the latitude of Cape Peschany and then, in the form of a thinner jet with lower SST, to the southern coast of the Tyub-Karagan Peninsula. The estimated propagation velocity of the South Caspian jet based on SST maps (approximately 12–22 cm/s at different stages of its northward progress) also agrees well with the model-estimated average monthly velocity (approximately 8–12 cm/s). The unusual northward propagation of the transverse upwelling jet, observed in successive satellite images in September 2003, can be explained by taking into account known instrumental measurements of the current structure during winds unfavorable for upwelling. The main similarities and differences between the results of satellite monitoring and numerical modeling of jet streams from the Northern Caspian, propagating near the eastern coast of the Middle Caspian from the Tyub-Karagan Peninsula to the south, are discussed.
