项目摘要
DYNAMO is a US research program motivated by the overall objective to expedite our understanding of processes key to the initiation of the Madden-Julian Oscillation (MJO) over the Indian Ocean. DYNAMO consists of four integrated components: a field campaign, data analysis, modeling, and forecasting. The field program is designed to observe the structure and evolution of cloud populations, their interaction with the large-scale environment, and air-sea interaction processes during MJO initiation. This project represents the ocean-side (subsurface) flux measurement program to complement surface flux measurements which are part of the air-sea interaction component of DYNAMO. The DYNAMO subsurface flux program focuses on air-sea interaction in the upper equatorial Indian Ocean, a key aspect for MJO initiation. This project will provide comprehensive measurements of the Indian Ocean barrier layer, upper-ocean mixing and entrainment as well as general surface layer behavior. Comprehensive and systematic upper ocean profiling of temperature, salinity, currents and turbulence will be executed during 35 days using proven instrumentation and techniques. This experiment's special focus will be assessment of changes in upper ocean heat content due to the combination of surface fluxes, depth-dependent solar heating (measured using in situ optical instrumentation) and subsurface divergence of turbulence heat transport (measured using the Chameleon CTD/ turbulence profiler). Advective contributions will be estimated from mooring arrays. These measurements will provide the basis for a determination of the physical processes underlying ocean/atmosphere feedbacks during the MJO initiation phase and for the parameterization of these processes in large scale ocean circulation models. These observations will be integrated into the DYNAMO/CINDY2011 program and made available to the general community to aid in understanding and predicting tropical climate systems. Inadequate representations of these processes in numerical models presently inhibit accurate simulation and prediction of MJO initiation. A better understanding of these processes is essential for improving their representations in numerical models.The DYNAMO subsurface flux program will introduce young scientists to complex, multi-scale air-sea interaction problems in the tropical climate system. DYNAMO observations will be used to calibrate and validate satellite retrievals, benefiting their application to much broader areas beyond MJO-related problems. Improved MJO simulation and prediction born from DYNAMO activities will enhance the capacity to deliver prediction and assessment products on intra-seasonal timescales for societal risk management and decision making, and to strengthen confidence in climate projections.
CNOO是美国的一项研究计划,其总体目标是加快我们对印度洋上空Madden-Julian振荡(MJO)启动的关键过程的理解。 CNOO由四个集成组件组成:现场活动,数据分析,建模和预测。 现场计划的目的是观察云群的结构和演变,它们与大尺度环境的相互作用,以及MJO启动期间的海气相互作用过程。 该项目是海洋一侧(次表层)通量测量方案,以补充作为海洋观测卫星海气相互作用组成部分的表层通量测量。 COMO次表层通量计划的重点是赤道印度洋上部的海气相互作用,这是MJO启动的一个关键方面。该项目将提供对印度洋障碍层、海洋上层混合和卷吸以及一般表层行为的全面测量。 将在35天内使用经过验证的仪器和技术,对上层海洋的温度、盐度、海流和湍流进行全面和系统的剖面测量。该实验的特别重点将是评估由于表面通量、与深度有关的太阳加热(使用现场光学仪器测量)和湍流热传输的次表层发散(使用Chameleon CTD/湍流廓线仪测量)的组合而引起的上层海洋热含量的变化。 对流的贡献将估计从系泊阵列。 这些测量结果将为确定MJO初始阶段海洋/大气反馈的物理过程以及大尺度海洋环流模型中这些过程的参数化提供基础。 这些观测结果将被纳入到CINDO/CINDY 2011计划中,并提供给公众,以帮助理解和预测热带气候系统。这些过程在数值模型中的代表性不足,目前抑制准确的模拟和预测MJO的启动。更好地了解这些过程对于改进它们在数值模式中的表现是必不可少的。热带海洋观测组织的次表层通量计划将向年轻科学家介绍热带气候系统中复杂的多尺度海气相互作用问题。 将利用COMO观测数据校准和验证卫星检索结果,使其应用于MJO相关问题以外的更广泛领域。改进的MJO模拟和预测产生于气候变化组织的活动,将提高能力,为社会风险管理和决策提供季节内时间尺度的预测和评估产品,并加强对气候预测的信心。
