There has been significant scientific progress over the past few decades in understanding the role of the ocean in climate and climate change. However, fundamental questions still exist, such as where in the global oceans and on what timescales do ocean circulations drive variations in upper-ocean heat content and sea surface temperature, and what role do those variations play in influencing events over land, such as episodes of drought and deluge, heat and cold, and storminess? The overarching goal of the project is to comprehensively quantify the role of variations in ocean circulation on global climate variability. This goal will be achieved through two main tasks. The first will be to diagnose the extent to which ocean circulations drive changes in sea surface temperatures using different observational data sets and ocean state estimates, and the second will be to conduct numerical modeling experiments to provide insight into the influence of those ocean-driven sea surface temperature changes on global climate variability. Together these tasks will lead to new perspectives on the role of ocean dynamic variability in the climate system, potentially leading to enhanced predictive skill of weather and climate events of direct relevance to human well-being and safety.The broader impacts of this proposal will result from its support and training of graduate students, which is required to sustain the pool of human resources needed for excellence in global atmospheric dynamics and climate research. Graduate students from communities underrepresented in climate science will be prioritized for support, and undergraduate students from historically underrepresented groups will be entrained by leveraging existing programs that provide research opportunities to those students. Moreover, all observational and model data generated by the project will be easily and freely accessible to the broader research community, and all results will be disseminated through publications in leading, peer-review scientific journals and through presentations of research results at prominent national and international climate workshops and conferences.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在过去的几十年中，在了解海洋在气候和气候变化中的作用方面取得了重大的科学进步。但是，基本问题仍然存在，例如在全球海洋中的位置以及海洋循环的哪些时间尺度驱动着上海洋热含量和海面温度的变化，这些变化在影响陆地上的事件（例如干旱和洪水，洪水，热和寒冷和寒冷和寒冷以及风暴和风暴之类的影响）中起着什么作用？该项目的总体目标是全面量化海洋循环中变化在全球气候变异性上的作用。这个目标将通过两个主要任务实现。第一个是诊断海洋循环使用不同的观察数据集和海洋状态估计的程度，第二个是进行数值建模实验，以洞悉这些海洋驱动的海面温度变化对全球气候变化的影响。这些任务将共同导致对海洋动态变异性在气候系统中的作用的新观点，有可能导致天气和直接相关的与人类福祉和安全性直接相关的气候事件的预测技能提高。该提案的更广泛影响将源于其对研究生的支持和培训，这是为了维持人类资源在全球大气中的卓越资源所需的支持和培训。来自气候科学领域不足的社区的研究生将优先供支持，而来自历史上代表性不足的团体的本科生将通过利用为这些学生提供研究机会的现有计划来纳入。 Moreover, all observational and model data generated by the project will be easily and freely accessible to the broader research community, and all results will be disseminated through publications in leading, peer-review scientific journals and through presentations of research results at prominent national and international climate workshops and conferences.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review 标准。
